The "new generation of avionics software radio" project for communication, navigation and surveillance (CNS) called "NextGen SDAR" consists of developing and integrating avionics software defined radio modules (SDAM) in a single hardware unit via a robust and optimized architecture. This project will make use of all the experiences and knowledge acquired during the previous NSERC projects AVIO-505 and AVIO-404, as well as their most significant achievements by proposing an architecture optimized for interoperability between the different SDAMs.

The ibNav project consists of implementing a real-time navigation system providing precise locations of soldiers during military operations. This system, which does not use a GNSS signal, presents a reliable alternative when the use of GPS is ineffective or impossible. This system will also provide 3D motion capture as well as mapping of the environment traversed by soldiers.

The project consists of continuing to develop the ibNav mobile GUI application for Milestone 4. This application is used to collect information from the sensors in order to display their data, but also to follow the movement of an agent on a map. The application works under Unity and is therefore multiplatform (iOS and Android).

The objective of this project is to offer a robust multi-platform application allowing to control and visualize the information provided by avionics software radio modules (SDAM), and this, in real time. This project aims to simplify laboratory tests as well as those in flight.

Creation of a Central control station allowing aggregation of ground units. Allows access to an interface to visualize the evolution of followed individuals. The interface display a simulated 2D/3D environment.

This research proposes to combine the measurements from a GPS receiver with high sensitivity with data from self-inertial navigation system and other complementary autonomous sensors such as odometers and magnetometers. Furthermore, in order to provide an affordable solution, the target system will be based exclusively on the use of sensors at very low cost. It is expected that this project will help reduce the environmental impact of motor vehicles, in addition, to have a significant positive impact on the overall safety of the vehicle.

This project consists of developing and integrating avionics software radio modules (SDAM) in a single hardware unit via a robust, certifiable and optimized architecture. This architecture will cover modernized avionics functions such as: VHF Ominidirectional Range (VOR), Instrument Landing System (ILS), Tactical Air Navigation (TACAN), Distance Measuring Equipment (DME), Automatic Dependent Surveillance Broadcast (ADS-B) In / Out, Trabsponder Mode-S (TMS), Wide-Band Radio (WBR) and radio altimeter, for civil and military use.

The ibNav6.0 RTOS firmware was especially developed to sense different environment changes and to track human body motion for indoor and outdoor application such as vertical and horizontal velocity indication, 3D positioning, change of floor detection, elevator detection, room change detection.

Ce projet de recherche consiste en la conception d’un canal d’acquisition et de poursuite compatible avec l’ensemble des particularités des signaux de navigation satellitaire des systèmes globaux, régionaux et d’augmentation (GNSS, RNSS et SBAS). Ces particularités incluent les codes d’étalement spectral de différentes longueurs et débits, différents schèmes de modulation et de combinaison en phase. Avec une telle diversité de signaux, le récepteur peut surmonter les limitations actuelles du GPS en termes d’intégrité des signaux, de la disponibilité continue d’une solution de positionnement, de sa précision ainsi que de résistance aux interférences (intentionnelles ou non) et ce, tout en préservant une basse consommation électrique, le rendant idéal pour les applications mobiles telles que les téléphones intelligents. Grâce à un faible nombre de canaux universels, le récepteur peut ainsi atteindre des performances similaires à celles de récepteurs ayant 200+ canaux dédiés.

The principal objective of the proposed research is to develop unaided multi-constellation techniques for weak signal applications, specially, indoor navigation. More specifically, the research project targets the design of a frequency-domain acquisition technique for weak signals with lower resource requirements than the existing ones. The proposed acquisition algorithm is adapted and modified for other GNSS constellations to be used for signal combination and to achieve higher sensitivities. To take advantage of the FFT blocks in the acquisition algorithm, the use of frequency-domain techniques and Wavelets for mitigating multipath signals is studied and a multipath mitigation method is proposed to improve the performance in weak signal conditions. A prototype of the proposed algorithms is implemented in Simulink as the baseband processing module of a software receiver. Sensitivity and robustness of the prototype receiver are evaluated using recorded signals captured from the output of a multi-frequency RF front-end. ----------------------------------------------------------------------------------------- Pour plus de détails, consulter : lassena.etsmtl.ca

Cette méthodologie va porter essentiellement sur la modélisation de l’architecture matérielle de la plateforme du système IMA tout en essayant de mener une exploration architecturale qui permet de mieux raffiner le modèle et apporter les optimisations nécessaires pour des contraintes bien précise

Les innovations technologiques introduites par l'apparition de système avionique modulaire posent de nouveaux défis aux acteurs de l'industrie aéronautiques. Les outils de conception et de vérification utilisés afin de développer des architectures fédérés ne peuvent être appliqués aux nouvelles architectures modulaires. L'objectif de ce projet est de définir une méthode permettant de minimiser l'effort de développement nécessaire à la migration d'un système avioniques fédérées vers un système avionique modulaire. La méthode suggérée devra établir un flot de conception afin de satisfaire les contraintes de communication. De plus, elle devra assurer le partitionnement spatial et temporel des diverses applications exécutées sur la plateforme modulaire

L'objectif de ce projet est de concevoir un DME (Distance Measuring Equipment) sur Matlab/Simulink et d'intégrer le module interrogateur dans une radio logicielle de type GNU. Pour son fonctionnement en temps réel, on se basera sur le document DO-189 de la RTCA (http://www.rtca.org/). Un DME est un système radio-transpondeur qui permet de connaître la distance qui sépare un aéronef d'une station au sol en mesurant le temps que met une impulsion radioélectrique UHF pour faire un aller-retour. Dans un premier temps, une trajectoire de vol du simulateur X-plane sera utilisée pour tester le modèle DME Simulink (cette trajectoire est mise comme entrée du modèle Simulink du canal de transmission). Dans un deuxième temps, le module interrogateur sera implémenté dans une radio logicielle de type GNU (USRP's) en utilisant Matlab et GRC (http://gnuradio.org). Un générateur de signaux DME (IFR 6000) sera utilisé en agissant comme équipement DME au sol pour les tests du module interrogateur.

La radio logicielle constitue un avantage pour les fabricants et équipementiers, d'une part, grâce à la disparition de certains composants analogiques coûteux et encombrants. D'autre part, les systèmes de positionnement par satellites sont couramment utilisés dans les transports maritimes, aériens et terrestres. L’objectif principal de ce projet consiste à mettre en œuvre une chaîne de réception complète des systèmes de géolocalisation GPS et Galileo en bande L1 dans une radio logicielle de type USRP N210 et faire varier différent paramètres afin d’améliorer les performances de navigation GNSS en termes de précision, de continuité et de fiabilité. Ces travaux permettront de tirer parti de tous les avantages de la radio de type logiciel dans le cadre du GNSS

Le projet consiste au développement d'un IMSI-CATCHER a base de la technologie radio logicielle (SDR) avec l’utilisation de logiciels opensource (Asterisk, OpenBTS …) et la carte USRP (Universal Software Radio Peripheral). L’objectif de la recherche est de développer un équipement avec les mêmes options que le produit commercial mais un à un prix beaucoup plus avantageux, ainsi que la réutilisation de la partie matérielle du même équipement pour autres objectifs avec un logiciel différent (Brouilleur sélectif).

test 800 car Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

Les systèmes embarqués en avionique deviennent plus modulaires et performants. Cette nouvelle capacité nous permet d’explorer la reconfiguration dynamique de système modulaire en avionique. Cette technique consiste à détecter un module fautif et d’en redistribuer les tâches sur les autres modules. La recherche a pour but de voir la viabilité et les performances rattachées à de tels mécanismes. Le prototype exploré comporte deux éléments principaux : • Un serveur central de communications capable de savoir l’état, la santé et la disponibilité de chaque module d’une plateforme IMA. • Une application à l’intérieur de chaque module capable de communiquer avec le serveur central et de recevoir un programme à charger en cas de panne d’un autre module.

The ibNav Project consists to use low-cost inertial sensors combined with inertial algorithms to obtain high efficiency in body navigation (also known as human motion) and indoor navigation. The system is capable of displaying (in real time) a 3D representation of moving subjects on Apple’s device: The iPad. Designed to research and development for industrials, potential uses are numerous and covers essentially two distinct sectors: Entertainment and military uses. In this research, the authors developed a prototype of body and indoor navigation. This system is composed of a network of 14 platforms IMU (Inertial Measurement Unit) using MEMS (Microelectromechanical Systems) sensors. These platforms are placed between each main joint of the body and equipped with Geomagnetic and Gyroscopes sensors working in three axes of its reference frame. Measurements are obtained from each platform and the local orientation is computed by implementation of navigation algorithms, such as AHRS (Attitude and Heading Reference System) and EKF (Extended Kalman Filter) integrated in the embedded system. Finally, the master platform computes for each sensor, an orientation in a specific reference frame and sends data by Wi-Fi protocol on the iPad device.

Ce projet de recherche consiste en l’élaboration, la mise en œuvre et la validation d’une stratégie permettant de déterminer la robustesse inhérente des autres éléments du système global, afin de définir les spécifications de fiabilité au niveau du sous-système embarqué. La piste de recherche qui sera suivie est l’application de signatures génériques de haut-niveau dans un modèle de simulation complet du système global, signatures émulant les comportements fautifs appréhendés de certaines parties du sous- système électronique embarqué. Les étapes liées à cette tâche feront suite à celles effectuées dans le cadre du projet CRIAQ AVIO403 (voir rapport d’étape), à savoir le choix de l'environnement de simulation système (i.e. Matlab) et le choix du premier système cible à modéliser.

The objective of this research/ project is to analyze, design, test and implement an Instrument Landing System based on Software Defined Radio (SDR). The SDR will actuate in the most risky phase of a flight, the landing. It will provide vertical and horizontal coordinates to the aircraft’s navigation system and airport air traffic control. The project will contribute to a better understanding of weaknesses, strengths and reliability of SDRs. Also, it will offer the basis to design and evaluate its interoperability with other software defined avionics radios in the aircraft. Furthermore, after the design, checking and completely validation of the software by Matlab/Simulink, additional tests will be conducted in flight simulators. And, in field, flight tests will be performed providing real data to be compared with the estimation acquired in the laboratory. To provide more flexibility and increase signal processing possibilities, the software will be developed programming C++. Moreover, the parameters for the operational airborne ILS during Glide Slope (RF Vertical coordinates) and Localizer (RF horizontal coordinates) will follow the standardization of RTCA/DO-192 and DO-195, respectively.

Dans le cadre du développement du récepteur GNSS hybride GPS du laboratoire LASSENA, ce projet consiste à réaliser une interface utilisateur qui permettra de piloter huit canaux RF indépendamment les uns des autres (carte RF). La communication entre l’interface utilisateur et la carte RF est développée autour d’un microcontrôleur ATmega32L. L’interface utilisateur est développée en langage C sous Visual Studio 2010. Une liaison UART permet au microcontrôleur de communiquer avec l’interface utilisateur sur PC. Le cahier des charges impose une communication par liaison SPI entre le microcontrôleur et la carte RF. La communication par liaisons UART et SPI est développée en langage C sous Atmel Studio 6. L’objectif est d’effectuer les tests de caractérisation de la carte RF durant les phases de conception et de fabrication de la carte Rx. Un rapport sur la caractérisation de la carte RF sera rédigé et mis à la disposition du personnel du laboratoire.

Le présent projet consiste à réaliser un système d’information intelligent, autonome et sans fil permettant à un individu de visualiser une information sur un écran LED et de changer l’information affichée à sa guise avec de simples gestuelles. Le système comprendra un écran LED de 60 pouces (en mode portrait), une carte faible puissance avec processeur embarqué possédant la capacité VGA/HDMI, un accès réseau Wifi et un senseur Kinect de Microsoft. L’étudiant développera une application embarquée qui affichera un Powerpoint, disponible dans un nuage informatique, sur l’écran LED. Ce Powerpoint sera contrôlé par des fonctions Kinect de base telles que « Diapositive suivante », « Diapositive précédente », « Pause », « Zoom-in », « Zoom-out », etc.

Le projet consiste à concevoir un système de communication Transponder Mode S, système déjà utilisé dans plusieurs avions. A terme, ce système est voué à être déployé sur l’ensemble du trafic aérien mondial, ayant un domaine d’exploitation beaucoup plus large que les modes A/C, ses prédécesseurs. L’avantage principal de ce système réside dans sa sélectivité. Ainsi, les stations radars au sol peuvent interroger de manière individuelle les avions équipés de ce protocole de communication, et échanger des données diverses grâce à une liaison de données. Un générateur de signaux Transponder Mode S sera utilisé afin de tester le Transponder développé, ce générateur faisant office de radar secondaire au sol. Le projet sera développé à l’aide de la radio-logicielle universelle GNU Radio, et de ses appareils associés d’Ettus Research USRP.

Le but de cette mobilisation est de mettre au point et d'améliorer le site Lassena d'une part. Ensuite, il va falloir réaliser un rapport scientifique dynamique à partir de la base de données du système ReLAN

This project aims to establish new design methods and digital signal processing techniques for robust and efficient universal navigation and communication equipment in the fields of aeronautics and aerospace. New avionic standards are under study and strong arguments exist for the adoption of software defined radios (SDR) at this point in time. The project anticipates the integration of multiple navigation and communication systems in a single hardware element. Such integration minimizes system footprint and avionic weight, reduces part count, and will incorporate more efficient new airspace management system (ADS-B), thereby reducing greenhouse gas emissions in the framework of international environmental initiatives. The aeronautic and aerospace industries have interest in a single generic reprogrammable and universal communication system used to replace multiple and burdensome radios/antennas presently used in aircrafts. The proposed system will allow for multiple radios that are simultaneously accommodated and have numerous functionalities, and will be implemented on a flexible integration platform suitable to future applications. The project will consist of integrating DME, Mode S transponder and wideband digital radio, built with novel software defined architecture proximal to the antenna. The architecture enables the capability to redeploy functionality based on phase of flight and minimizes connectors, antennas, cable length, electromagnetic interference (EMI) and system footprint. The goal is to digitize the radiofrequency (RF) signal in proximity to the antenna and to transmit the baseband signal to a generic radio for further digital signal processing. The proof-of-concept demonstrator will be evaluated in-laboratory and in-flight using simulation equipment and a flight test platform under real operating conditions in order to characterize protocols and system performance. The project will contribute to international initiatives for the definition of new standards and contribute to Canadian efforts to reduce greenhouse gas emissions, and create new employment opportunities for the team of highly qualified personnel.

This project aims to establish new design methods for robust and efficient automotive navigation and optimal management of a fleet of vehicles in harsh environments. In addition, the project also aims to develop innovative metrics for real-time analysis of dangerous driving behaviour as well as real-time analysis of car accidents in order to significantly improve global safety of Canadian drivers. In general, this research proposes to combine measurements from a high sensitivity GPS receiver with data coming from a self-contained inertial navigation system and other complementary autonomous sensors such as odometers and magnetometers. Moreover, in order to provide an affordable solution, the targeted system will be based exclusively on the use of very low cost sensors. It is expected that this project will help reduce the environmental footprint of motor vehicles in addition to having a significant positive impact on overall vehicle safety. For example, improving vehicle localisation accuracy and robustness in harsh environments can significantly reduce the time to find a stolen or misplaced vehicle, which can have an important impact on Canadian companies’ finances. Furthermore, having a robust and precise solution for monitoring vehicle behaviour can lead to the implementation of a new taxation system based on car usage or on driving behaviour, which according to recent studies, can help reduce vehicle greenhouse gas emissions by up to 10%. In addition, accurate reconstruction of car accidents in real-time allow prediction of specific parameters of an accident scene thus improving reaction time and vehicle safety. The proof-of-concept demonstrator will be evaluated in-laboratory and on-road using simulation equipment and a car test platform under real operating conditions in order to characterize protocols and system performance. The project will contribute to international initiatives for the definition of new standards and contribute to Canadian efforts to reduce greenhouse gas emissions, and create new employment opportunities for the team of highly qualified personnel.

Les interfaces avec le pilote ou les senseurs utilisés à bord des aéronefs modernes sont toujours plus sophistiquées pour fournir un environnement plus sécuritaire au pilote. On peut nommer des systèmes comme les Glass Cockpits, les environnements synthétiques et la vision augmentée comme exemples de ces outils que les pilotes utiliseront pour des vols plus sécuritaires. Ces systèmes sont extrêmement complexes mais doivent être conçus de façon tout aussi rigoureuse. Cette recherche a pour but d’apporter un savoir-faire méthodologique permettant d’incorporer des techniques modernes de conception architecturale ayant le potentiel de mieux gérer la complexité de systèmes avioniques complexes.

Mise en place depuis maintenant 4 ans, le projet UGC (Universal Glass Cockpit) a pour but de développer sur iPad un tableau de bord logiciel pour la navigation aérienne. En se connectant en wifi sur un simulateur logiciel de vol, le simulateur de vol Marinvent présent au laboratoire LASSENA ou même à un avion PIAGGIO AVANTI, l’UGC permet d’avoir accès l’ensemble des équipements d’un tableau de bord réel (altimètre, indicateur de situation horizontale, etc…) mais aussi à d’autres instruments plus sophistiqués comme un FMS ou la possibilité d’enregistrer la totalité des paramètres du vol afin de les rejouer par la suite. Il permettra par la suite la navigation à quatre dimensions ainsi que la possibilité de se connecter à une radio universelle afin de recevoir et d’émettre des données encore une fois par le wifi.

The objective of this research project is to develop a low-cost integrated automotive navigation system based on a novel multi-sensor architecture and on advanced data fusion techniques. Technological progress in this domain will enable the implementation of new commercial services related but not restricted to vehicle theft protection, fleet management, automated car navigation and emergency assistance in challenging environments. More specifically, the availability of such accurate and robust navigation solution with a high level of integrity could lead to the implementation of new taxation services based on the "pay as you drive" or "pay how you drive" paradigms which are currently in great demand by the automotive insurance industry. This research project is realized in collaboration with iMetrik Global inc. and Future Electronics inc. and is supported by a Collaborative Research and Development Grant from the Natural Sciences and Engineering Research Council of Canada.

Satellites act as relay stations and form a critical part of the world-wide communications infrastructure. They are used for communications, positioning, remote sensing, in civil and/or military applications such as Digital Video Broadcasting (DVB), high-definition video, amateur radio communications, broadband Internet, weather forecasting, environment surveillance, Global Navigation Satellite Systems (GNSS), etc. Satellite Communications (SatCom) systems are sensitive to Radio Frequency Interference (RFI). The rapid rate of technological developments will continue to lower the entry barrier for space, increasing the number of players in the space arena. This fact, in combination with the ever-increasing thirst for satellite communications bandwidth, will inevitably lead to a dramatic increase in RFI. Unfortunately, because of RFI’s variety of sources and causes, RFI is a challenging problem for researchers, operators and manufacturers. The AVIO-601 project aims to develop a technical framework for the detection, measurement and mitigation of RFI to resolve satellite link interference issues and increase the global robustness of SatCom systems.

This project aims to develop new methods to detect, measure, characterize, locate and suppress in real time radio frequencies interference (RFI) in satellites communication systems (SatCom). Acting as relay stations, satellites are meant for scientific applications for surveillance, remote sensing, telecommunication, radio-navigation, allowing to offer numerous civil or military services on a global scale. One of the aim of the project AVIO-601 is to develop new solutions to reduce and mitigate interference more efficiently by using an approach based on signal processing, cognitive software radio and reconfigurable antennas. In this context, the major objective is to develop, conceive and integrate multiple modules for detection, localisation, measurement, characterization and interference mitigation to reduce the negative impact on SatCom.

Satellites act as relay stations and form a critical part of the world-wide communications infrastructure. They are used for communications, positioning, remote sensing, in civil and/or military applications such as Digital Video Broadcasting (DVB), high-definition video, amateur radio communications, broadband Internet, weather forecasting, environment surveillance, Global Navigation Satellite Systems (GNSS), etc. Satellite Communications (SatCom) systems are sensitive to Radio Frequency Interference (RFI). The rapid rate of technological developments will continue to lower the entry barrier for space, increasing the number of players in the space arena. This fact, in combination with the ever-increasing thirst for satellite communications bandwidth, will inevitably lead to a dramatic increase in RFI. Unfortunately, because of RFI’s variety of sources and causes, RFI is a challenging problem for researchers, operators and manufacturers. The AVIO-601 project aims to develop a technical framework for the detection, measurement and mitigation of RFI to resolve satellite link interference issues and increase the global robustness of SatCom systems. The main strategic goal of this project is to develop novel cognitive system architectures and digital signal processing techniques to detect, localize, characterize and suppress RFI in SatCom networks and to demonstrate their feasibility in real world situations through implementation of a proof-of-concept hardware/software prototype. An additional objective is to develop an RFI atlas platform, that is, a complete database of RFI sources, characteristics, and locations that will be updated in real-time by an RFI measurement and monitoring module. The project will also study the potential of using reconfigurable antennas as a means to reduce RFI at the radiofrequency hardware level.

Research project on the development of a new control method.

A TCXO can drift in frequency compared to the time reference signal of GPS satellites. This drift is mainly caused by temperature variations of the components. To correct this drift, the frequency of the TCXO is voltage controlled within a DPLL. This DPLL calculates a correction to be applied according to the phase difference between the 1PPS of the GPS and the 1PPS created from the TCXO. In parallel to the DPLL, the algorithm follows the applied correction signal to model the frequency drift characteristics of the TXCO. The learned model is used when the GPS time reference signal is lost, to provide a time correction to the TXCO until the GPS signal is reacquired. The target performance is to maintain an accuracy of less than 1 microsecond without a GPS system for at least one hour over an operating temperature range of - 40 to 80 °C. Moreover, the objective is that the system needs the GPS signal for 11 hours, i.e. 9 hours for the PLD to stabilize and 2 hours for the model to converge.

The prime objective of this research would be to conduct autonomous precision landing of an Unmanned Autonomous Vehicle (UAV) on mobile platforms including maritime platform and military vessel helipad. The developed system will be used on LX300, a real and considerable dimensions twin-rotor unmanned helicopter, manufactured by Laflamme Aero and with the goal of maritime surveillance. This UAV will navigate in area where there are no navigation beacons and will only be able to use satellite systems. However, maritime decks are small and can’t handle traditional beacon system because of their structure and are subject to the strong swell which cause big attitude changes. Hence, this matter necessitates better alternatives to get a better accuracy than a GNSS system, and the synchronization of the drone and the platform to get a soft, accurate and safe landing for both the drone and the platform. To materialize this goal, two parallel systems will be developed to compute the relative distance and the relative attitude between the drone and the platform: 1. The first consists of a robust system of tracking the position of the drone in relation to the platform, calculating the range and synchronizing attitude by communicating between two little sized modules, one on the platform and the other on the drone. A GPS/Real Time Kinematic (RTK) system will be used for relative position and a relative IMU/AHRS system to synchronise attitudes. 2. The second method is to use a lightweight vision system along with four rangefinders. The First phase would be detection of the landing zone from a certain distance. Then, the trajectory will be built, and the control action will be computed. In succeeding stage, the camera will keep the rotorcraft oriented with ship landing deck and simultaneously the rangefinders will model the attitude of the landing zone. Lastly, the most optimized and safe time will be calculated, and the final alighting task will be conducted. Finally, to approach a more effective system these sensors data will be fused, using filters like extended Kalman filter and unscented Kalman filters.

The objective of our project is mainly related to the hardware part of the avionics systems and more particularly to the design of last RF systems. The challenge is therefore to use recent technologies where reliability and robustness criteria are essential.

IMUs (Inertial Measurement Unit) are used for pedestrian navigation. Nowadays, these sensors are in each smartphone. IMU's main advantages are its energy low-consumption, its ability to work in every environment type (such as indoor and outdoor) ,and its independancy regarding external elements (contrary to GNSS systems). However, its main limit is noise which causes a drift when measurements are integrated. To redue this drift, we will use artificial intelligence with reinforcement learning and neural networks. Our main goal is to provide an accurate positionning on 1-hour IMU data.

MASU: This project is aimed at setting up an automated system for landing a UAV on a mobile maritime platform. ibNav: This project is aimed at providing a lightweight and modular solution for indoor navigation with real-time fluid 3D motion capture capability.

This project concerns the design of an ADS-B In / Out (Automatic Dependent Surveillance-Broadcast, http://en.wikipedia.org/wiki/ADS-B) which is positioning system used for aircraft surveillance. The tendency to integrate all the avionics systems into a reprogrammable radio, we will therefore have to implement this avionic system with MATLAB / Simulink before embedding it in a BladeRF v2.0 software radio from Nuand available at ÉTS. An ADS-B signal generator could be used to test the aspect "In" of our program, as well as our system could also generate messages that will be processed by an ADS-B signal receiver. Then, we will interest to the validation of this module using the Cantata tool which will demonstrate the certifiability of this system. Then finally test it at an airport, if time permits.

The goal of my internship is to study and compare multiple AHRS algorithms to fulfill the needs of the iBNav project. These algorithms use Kalman filters to estimate a pedestrian's heading using accelerometers, gyroscope and magnetometers. The two main algorithms that are compared are the "Unscented Kalman Filter" (UKF) and the "Cubature Kalman Filter" (CKF).

The objective of this project is to provide a modular and lightweight solution for indoor body navigation with the capability of real-time fluid 3D motion capture. The proposed and developed system will have both indoor and outdoor PNT capabilities, as well as accurate limb attitude determination and robust activity recognition. Scalable sensor array and autonomous runtime IMU calibration will be used in the system to improve its performance.

GPS signals are high enough in frequency to reflect from building surfaces. These reflected signals commonly combine with signals directly from satellites causing multipath interference. A few techniques are commonly employed to mitigate multipath interference. Wider band signals, now available from recent satellite constellation additions, have yet to be fully exploited for both multipath mitigation and very precise indoor positioning. Coherent correlations of wide band signals permit a greater understanding of multipath reflection to a greater degree. This research is concentrated on discovering and reducing to practice the application of the correlation of multiple wideband signals in a coherent fashion, by studying the minutia of signal propagation characteristics such as reflection from, and penetration through, building structures. This will improve the robustness of GPS signal processing for hostile environments.

The student will work on the CRSNG / CRIAQ RDC project “new generation of avionics software radio” for Communication, Navigation and Surveillance (CNS) called "NextGen SDAR" which consists of develop and integrate avionics software radio modules (SDAM) into a single hardware unit robust and optimized.

He will learn to perform simulations and laboratory tests and to document everything in a certifiable way for aviation authority. He will also learn how to prepare and document flight tests used to validate results in a real environment using several planes. The goal to achieve is to process RF signals while being compliant to Radio Technical Commission for Aeronautics.

The ibNav project consists in an embedded system allowing the positioning in an environment where GPS localization systems are weak or unavailable.

The objective of my internship in this project (AVIO-601) is to develop an interference attenuation system on the DVB-S2 modem in order to improve its performance in terms of JSR and BER. This project, carried out in collaboration mainly with Mohammad Hossein Same, consists of implementing a CWI-type interference detection and suppression algorithm in a BEE-Cube SDR. This project is carried out partly by simulation on Matlab Simulink and partly with the algorithm implemented on the SDR FPGA. Several methods of attenuation and interference detection are studied to determine the most effective for such a system. One of the major constraints to interference suppression is the quality of the signal after filtering. The goal is to remove the interference entirely, without damaging the quality signal around it. The type of filter used is a first order IIR notch filter.

The project focuses on the design of optimal algorithms at the lowest level in data transfer modules, processed at the physical level, under the control of the SDA module.

The main objective of this project is to give a complete overview of the functionality of the transceiver module, the classical algorithms used, and to propose optimal algorithms, which will allow the minimization of errors.

Comparative study of driving performance and accident analysis on a 6DOF test bench and in real application environment for the introduction of new charges PHYD and PWYD The main objective of this project is to study the driving performance of a vehicle driver in various environments to allow the introduction of new payments methods like PHYD and PWYD. The objectives are to develop and analyze new analysis metrics to evaluate the driving behavior and to study the performance of these metrics in order to validate and quantify them.

This research project aims to simulate the driving behavior of a vehicle in a driving simulator (eg SCANER Studio). A Micro-iBB is used to collect inertial and GPS data of real driving. It is possible to drive again in the simulator room in an identical artificial environment. The analysis of the data makes it possible to quantify the differences between real and simulated driving as well as to improve the settings of the simulated vehicle. Using a plugin, the input data is emulated to the data extracted from the Micro-iBB. The project is to relive a journey in augmented reality using 6DOF platform and VR headset. This technology allows the analysis of crashes a posteriori or even play high feelings drives, like Formula 1 laps.

The main objective of this project is to improve the flexibility and performance of an Autonomous Vehicle Bench Test (AVBT) for the validation and qualification of car driving behavior and accident diagnostic metrics.

The research project is to build up a simulation system connecting the CKAS motion and VR. Through the connection with a computer, the vision and motion will be projected to the VR and the 6DOF CKAS W3S accordingly when running the software (Assesto Corsa and X-plane 10). The following work is to plug in the data collected to the software called City Car Driving. The mission is to collect the data (such as acceleration, speed, etc.) under different circumstances from a real car by connecting with the Micro-iBB and send these data to the computer through a UDP sender converter to the SCANER Studio, which let the person sitting on the CKAS motor feel the vibration and vision using VR without driving a car or playing the games. The SCANER Studio is specifically used since there will be different aspects like the acceleration or brake which suits the situation while driving the car.

This project aims to transform old unusable planes into low-cost flight simulators. Hence, we are going to develop a system able to stimulate the sensors of a real plane based on a flight simulator environment. The physical commands on the plane will be interpreted and transmitted to the flight simulator in order to update its environment.

The goal of this project is to simulate the on flight behavior of an aircraft on the ground, out of use. The simulation starts with flight maneuvers made from the simulator X-plnane. Then navigation data from X-plane will be sent to a low-cost system to design. This system will allows primary and secondary avionic systems to show the same data as the simulator.

The global objective of the research is to develop advanced navigation and attitude estimation algorithms to realize robust navigation in harsh environment and ultra-precise attitude target determination. The inertial MEMS sensor calibration methods and nonlinear algorithm integration method are the most important techniques for precise attitude determination. The role of Prof. Cheng is focusing on nonlinear adaptive integration navigation algorithm of low cost MEMS and GPS receiver, which can make the uncertain noise characteristics be online estimated to adaptively compensate the time-varying noise characteristics. In the meantime, designing compensation algorithm for the inertial sensor error and attitude error with GPS receiver aiding can make the attitude determination more stable and robust. This new technologies will be applied to two research projects at LASSENA named VTADS and FSAR projects.

The first objective is to make sure that all theoretical developments made by the research team will converge into a new architecture of prototypes that will Detect, Geolocate, Measure, Monitor and Mitigate all types of Radio Frequency Interferences (RFI) for next generation satellite communications.

Study and realization of UAT (universal access transceiver) modem technical concerning air/air and air/ground communications in a software radio. The UAT standard is that choosen by Americans for ADS-B system communication. The Modem will also adapted in VDB Modem(VHF data broadcast) which is the standard used for GNSS Safety-of Life receivers. First, both Modems will be tested in laboratory with emulators of canal then in real time with an airplane and a real limk. A graphic interface will allow to control both Modems.

This project is to develop certain blocks of a DVB-S2 satellite receiver. The modules mainly include a the COF (Carrier frequency Frequency Offset) estimator, a LDPC (Low-Density-Parity-Check) decoder, a BCH (Bose-Chaudhuri-Hocquenghem) decoders and a MPEG-2 decoder. An offset on the carrier frequency results in a variation in time of the phase error. This is due to the Doppler effect and it is necessary to implement a COF estimator in order to synchronize the carrier. In addition, the first decoding step (LDPC+BCH) makes the data insensitive to Additive White Gaussian Noise (AWGN) linked to the channel. This ensures virtually error-free transmissions. The second decoding (MPEG-2) consists of reading the binary data and displaying the corresponding video. All the receiver's faculties will be exploited (FPGA + microprocessor).

This project involves the suppression of spurious signals (jammers for example) during a digital communication, GPS type for example. These signals have frequencies that are a priori unknown. Thus, an adaptive filter needs to be designed for the purpose of detecting this frequency by updating these coefficients and eliminating the jamming signals. A Piranha filter’s cell is in two parts, one for detection of frequency(ARMA) and the other for the elimination(MAAR). We use this one because it is possible to cascade many independent cell. Finally, scrambling could be suppressed during satellite communication.

Les systèmes avioniques deviennent de plus en plus complexe ce qui rend les outils de simplification du développement plus important à la fois pour la création de nouveaux systèmes ainsi que pour la mise à jour de systèmes déjà existants. La technologie de logiciel DDS (Data Distribution Service) a été conçue pour simplifier les communications entre différentes applications temps réel qui ont un haut niveau de criticité, tel que les applications avioniques. Ce projet a donc comme objectif principal de démontrer la viabilité de l'utilisation d'un logiciel de communication DDS pour les communications entre les noeuds des systèmes IMA (Integrated Modular Avionics). Pour ce faire, il faudra mesurer la latence, le débit et le déterminisme des communications sur un démonstrateur IMA muni d'un logiciel de communication DDS. De plus, ce projet vise également à établir une méthodologie pour implémenter la technologie DDS au sein d'un système IMA.

The development of mult GPS receivers system, through integrating three or more GPS receivers into one system, has recently received attention as an accurate attitude measurement system in navigation. This kind of systems not only use GPS signals to obtain position, velocity, acceleration and jerk with high accuracy, but also can determine the attitude of a moving object, a vessel or an aircraft in real time. Until now, those systems suffer from lack of accuracy, high cost and complexity of use. In contrary, such systems are intrinsically drift free which makes them advantageous to traditionally used of Inertial Navigation Systems (INS). Differential GPS carrier phase measurement technique has some advantages over more conventionally used pseudorange measurement technique such as having lower noise and multipath error. However, this method suffers from major drawbacks such as integer ambiguity, precision and processing load. The objectives of the project are: 1) To develop a real-time low cost prototype which is able to process real raw GPS/GNSS measurements to measure 3D attitude determination with high precision and resolution 2) To compare the performances of different GPS attitude determination algorithms, first using GPS L1 and then, investigating advantages of using multi-GNSS signals 3) To determine the position of a target at 1km within a 2D positioning max error of 1 meter with a maximum of 4 GPS/GNSS receivers 4) To investigate processing DSP load of running real-time developed attitude determination algorithms 5) To investigate the improvement of using other GNSS signal

The integration of different avionics systems is what the aerospace industry has been pursuing for years. To this end, LASSENA proposed an architecture model based on SDR. The solution presently provided combines a GPP and an FPGA with an effective exchange data between the two processing units. In this context, this graduation project has been drawn up; it consists in making the link between the two units more reconfigurable. During the same project, a system has been designed to ensure the sharing of resources with other avionics systems, namely “Wideband Radio”. In this.system, a frequency locked loop has been added to help reduce the frequency offset. Due to the complexity of the FLL and the limited GPP resources, the FLL has been implemented in FPGA. Finally, an experimental validation was performed on the equipment and during the flight tests.

This internship consists of integrating various avionics functions developed in a software radio and testing these functions inside a flight simulator with real RF signals. Tests in different flight scenarios will evaluate the performance of the systems inside the flight simulator. The avionics software radio with several CNS (Communication, Navigation and Surveillance) functions can also be tested in flight with our engineering team.

In this project, I need to developp a Python application and a Qt graphic interface working with ultra-modern radio system platform (http://nutaq.com/en/sdr-comparison-chart) to insure a control on already working avionic system au LASSENA (DME, ADS-B et TMS) by using GNU Radio (http://gnuradio.org/). I will also migrate communication protocol from Ethernet to PCI-express in a Linux environment to improve the global system performance. I will take part in integration tests on the new system and explore new execution options and architecture developpement reconfiguration based on the actual architecture.

Integration of navigation, communication and surveillance systems under a single universal reconfigurable platform

This project aims to establish new design methods and digital signal processing techniques for robust and efficient universal navigation and communication equipment in the fields of aeronautics and aerospace. New avionic standards are under study and strong arguments exist for the adoption of software defined radios (SDR) at this point in time. The project anticipates the integration of multiple navigation and communication systems in a single hardware element. Such integration minimizes system footprint and avionic weight, reduces part count, and will incorporate more efficient new airspace management system (ADS-B), thereby reducing greenhouse gas emissions in the framework of international environmental initiatives. The aeronautic and aerospace industries have interest in a single generic reprogrammable and universal communication system used to replace multiple and burdensome radios/antennas presently used in aircrafts. The proposed system will allow for multiple radios that are simultaneously accommodated and have numerous functionalities, and will be implemented on a flexible integration platform suitable to future applications. The project will consist of integrating DME, Mode S transponder and wideband digital radio, built with novel software defined architecture proximal to the antenna. The architecture enables the capability to redeploy functionality based on phase of flight and minimizes connectors, antennas, cable length, electromagnetic interference (EMI) and system footprint. The goal is to digitize the radiofrequency (RF) signal in proximity to the antenna and to transmit the baseband signal to a generic radio for further digital signal processing. The proof-of-concept demonstrator will be evaluated in-laboratory and in-flight using simulation equipment and a flight test platform under real operating conditions in order to characterize protocols and system performance. The project will contribute to international initiatives for the definition of new standards and contribute to Canadian efforts to reduce greenhouse gas emissions, and create new employment opportunities for the team of highly qualified personnel. The developed technologies will also be applicable to ground or airborne infrastructure.
