Next Generation e-Transponder (NGeT)

Researchers:

René Jr Landry

Beginning date:

1 September 2014

Project duration :

2 years

Description :

This contact between MDA and ÉTS supports a collaborative effort in technology development for the application of innovative approaches in remote sensing and geo-modelling to monitor surface deformation and change in pipeline rights of way using Synthetic Aperture Radar (SAR). Specifically, on the developing proof-of-concept technologies for next-generation electronic transponders, which allow active ground-based signals to be detected within SAR imagery and used as point targets during data analysis and interpretation.

MassE de DOnnées de Conduite pour modélisation d’un feed-back incitant à la conduite sécuritaire selon les déplacements des automobilistes (MEDOC)

Researchers:

René Jr Landry, Patricia Delhomme (IFSTTAR) and Guillaume Saint-Pierre (IFSTTAR)

Beginning date:

5 January 2015

Project duration :

2 years

Description :

The research project MEDOC is devoted to the study and analysis of the drivers’ mobility. This joint project is led by Ifsttar in collaboration with École de technologie supérieure (ÉTS). The role of ETS is to provide 40 electronic Micro-IBB black-boxes to be installed by 200 motorists living in Île-de-France, in the department of Yvelines (78), or various cities selected through the departments of Essonne (91), Hauts-de-Seine (92) and Val de Marne (94). The recorded data should allow learning vehicle dynamics and then relating these data to the characteristics of road infrastructure. This innovative method is complementary to common experimental and epidemiological studies to assess driving behaviours in natural environment "with minimum interference", also known as naturalistic approach. This equipment combined with the completion of a log book will allow recording data related to vehicle behaviour as well as the incidents encountered by the participants during their travels. This project will provide an overview on the drivers’ mobility through primarily many variables related to the vehicle dynamics or driving tasks and also through "Big Data" post processing analysis. This information will be available for all the trips of 200 volunteer motorists, for a two-month period (excluding pre-tests). With these wealth data, it should be possible to better understand many driving behaviours for which very little information were available until now. A paradigm shift should then be feasible regarding the safest, cleanest, most efficient mobility that this technology will allow to drivers.

iMACGR - Cognitive Multi‐Antenna GNSS/INS Receiver Architectures and Methods for Indoor‐Denied Navigation

Researchers:

René Jr Landry

Description :

The main objective is to solve present technological limitations and scientific challenges related to GPSDenied navigation for indoor environments, autonomously, without any external infrastructures (WiFi, GSM, RFID, etc.). Promising new digital signal processing architectures and methods will be investigated to enable indoor tridimensional precise positioning, navigation and to determine robust 3D spatial attitude of an autonomous GNSS receiver. This receiver will dynamically evolve in extremely weak navigation satellite signal scenarios (so-called “indoor”). The program will exploit notably system redundancy, new properties and possibilities of existing new GNSS signals. To enable such new capabilities, the methodology will investigate first the advantages of using a multi-antenna GNSS receiver. This in-house receiver has all capabilities to receive any kind of available GNSS signals from multiple antennas (typically 2 to 8). GNSS signal and frequency diversity analysis along with multipath signals and high sensitivity processing will be investigated using a patented and fully “open-design” universal GNSS architecture. The second major initiative will be conducted based on the principles derived from the telecommunication cognitive radio (CR) technology. This unique receiver will be referred to as the “intelligent Multi-Antennas Cognitive GNSS Receiver (iMACGR)”. A third investigation will aim to evaluate benefits of using raw measurements from very low cost inertial sensors such as 3D gyroscope, accelerometer and magnetometer, with adaptive learning processes to assist the iMACGR indoors. Several potential billion dollar industries will emerge by these GPS-Denied applications. The results of this program will open a completely new area of applications with GNSS navigation and reliable attitude determination indoors. This research program will strongly contribute towards new indoor guidance capabilities and businesses, new applications and security improvements for first responders, tourism, medical, defense and transportation industries, etc. This research program will directly be profitable to other numerous applications and engineering fields, including telecommunications and geomatic sciences.

AVIO 601 - Interference Mitigation in Satellite Communication

Researchers:

R. Jr Landry (ÉTS, Lead), O.A. Yesté (ÉTS), W. Ajib (UQAM), B. Le (INRS), J-J Laurin (École Polytechnique), C. Nerguizian (École Polytechnique), Y.R. Shayan (Université Concordia)

Description :

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. The AVIO-601 project team will consist of 16 students, and 3 professionals. The proposed research program will provide a platform for the training of highly-qualified personnel in innovative architectures and new concepts of adaptive filtering, blanking, signal authentication, encryption, adaptive equalization, adaptive antenna beams and resource management, null steering, etc.

Autonomous Mission for On-Orbit Servicing (AMOOS)

Researchers:

René Jr Landry

Beginning date:

2 September 2013

Description :

The AMOOS Project aims to produce a business plan related to the design and execution of autonomous missions for on-orbit servicing based on orbital Unmanned Aerial Vehicle (UAV).

Project FSAR : Ultra-Precise and Robust Attitude Target Determination

Researchers:

René Jr Landry

Beginning date:

1 May 2013

Project duration :

4 years

Description :

This project is related with the Soldier Systems Technology Roadmap (SSTRM) which is a government-industry-academia collaboration aimed at enhancing the operational effectiveness of the future Canadian soldier. The Capstone Report and Action Plan (2011–2025) have established a technology roadmap for the future Canadian Soldier (www.materiel.forces.gc.ca/en/sstrm.page). One of the Capstone research projects consist in determining the precise location of a target without optical laser. The principal objective of the 4 years ÉTS research project is to develop advanced attitude estimation algorithms and inertial MEMS sensor calibration methods to establish robust and precise attitude estimation using medium to high grade MEMS inertial sensor combined or not with GPS receiver in an outdoor environment. The project will focus on the triad assembly calibration methods, temperature compensation techniques, precise reference determination and precision GPS attitude determination using direct satellite navigation signals. Some researches will be 1) high accuracy/fidelity inertial sensor error models, application of nonlinear geometric control theory for attitude stabilization and precision measurement, etc.

The main differences of this project compare to the discovery program are numerous 1) the attitude determination needs to be done outdoor with open sky view of GPS satellites, 2) the grades of the MEMS sensors are from medium to high, 3) the developed algorithms will not use multipath GPS signals, nor weak GPS signal or low cost MEMS grade sensors, 4) research problematics and techniques are different.

Vehicle Tracking and Accident Diagnostic System (VTADS)

Researchers:

R. Jr Landry (ÉTS, Lead), D. Gingras (University of Sherbrooke)

Beginning date:

1 May 2013

Project duration :

4 years

Description :

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.

Avio 505 : Software radios for highly integrated system architecture

Researchers:

R. Jr. Landry (ÉTS, Lead), M. Sawan (Ecole Polytechnique), A.Wessam (UQAM), F. Nabki (UQAM), F.Gagnon (ÉTS), C.Thibeault (ÉTS)

Beginning date:

3 September 2012

Project duration :

4 years

Description :

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.

MethoRad : Méthodologie de conception, vérification et test des systèmes embarqués tolérants aux radiations cosmiques

Researchers:

Claude Thibeault (ÉTS, Lead), Jean-François Boland (ÉTS), Yvon Savaria (Poly), Maarouf Saad, Yves Audet (Poly), Yves Blaquière (UQAM)

Description :

The constant reduction in the size of the transistors makes electronics generally more sensitive to the effects of cosmic radiation, which has an impact on the reliability of embedded systems subject to these radiations. Some stakeholders in the aviation do not hesitate to identify the radiation as the causes of the increase they noted in the number of cases of malfunctioning equipment malfunction disappears after the offending equipment has been reset. The main objective of this project is the adaptation of conventional methods of integration (from design to test) of embedded systems to take into account the effect of cosmic radiation on electronic modules required level of reliability, in the presence of programmable FPGA circuits.
