abstract = {The Internet of Things (IoT) is a technology that can connect billions of devices or “things” to other devices (machine to machine) or even to people via an existing infrastructure. IoT applications in real-world scenarios include smart cities, smart houses, connected appliances, shipping, monitoring, smart supply chain management, and smart grids. As the number of devices all over the world is increasing (in all aspects of daily life), huge amounts of data are being produced as a result. New issues are therefore arising from the use and development of current technologies, regarding new applications, regulation, cloud computing, security, and privacy. The blockchain has shown promise in terms of securing and preserving the privacy of users and data, in a decentralized manner. In particular, Hyperledger Fabric v2.x is a new generation of blockchain that is open source and offers versatility, modularity, and performance. In this paper, a blockchain as a service (BaaS) application based on Hyperledger Fabric is presented to address the security and privacy challenges associated with the IoT. A new architecture is introduced to enable this integration, and is developed and deployed, and its performance is analyzed in real-world scenarios. We also propose a new data structure with encryption based on public and private keys for enhanced security and privacy.},

abstract = {This paper proposes a novel Blockchain-based indoor navigation system that combines a 

foot-mounted dual-inertial measurement unit (IMU) setup and a zero-velocity update (ZUPT) algorithm 

for secure and accurate indoor navigation in GNSS-denied environments. The system estimates 

the user's position and orientation by fusing the data from two IMUs using an extended Kalman filter 

(EKF). The ZUPT algorithm is employed to detect and correct the error introduced by sensor drift 

during zero-velocity intervals, thus enhancing the accuracy of the position estimate. The proposed 

Low SWaP-C blockchain-based decentralized architecture ensures the security and trustworthiness 

of the system by providing an immutable and distributed ledger to store and verify the sensor data 

and navigation solutions. The proposed system is suitable for various indoor navigation applications, 

including autonomous vehicles, robots, and human tracking. The experimental results provide clear 

and compelling evidence of the effectiveness of the proposed system in ensuring the integrity, privacy, 

and security of navigation data through the utilization of blockchain technology. The system exhibits 

an impressive ability to process more than 680 transactions per second within the Hyperledger-Fabric 

framework. Furthermore, it demonstrates exceptional accuracy and robustness, with a mean RMSE 

error of 1.2 m and a peak RMSE of 3.2 during a 20 min test. By eliminating the reliance on external 

signals or infrastructure, the system offers an innovative, practical, and secure solution for indoor 

navigation in environments where GNSS signals are unavailable.},

abstract = {This paper provides research on the enhanced NextGen ADS-B reception method and its performance in laboratory and flight tests. It sheds the light on end-to-end reception techniques to comply with key requirements. ADS-B has emerged as among the most intriguing avionics for both researchers and companies since the launch of NextGen in 2009. ADS-B provides authorities with a mechanism for use in continuously monitoring the position and track of an airplane using periodic and independent broadcast messages that transmit Global Navigation Satellite System (GNSS) position information. The enhanced pulse detection technique is used to detect and validated preamble pulses. Besides the utilization of multiple amplitude samples technique not only improve bit and confidence declaration accuracy but also make it capable of deploying error detection/correction algorithms which are two aspects of enhanced Extended Squitter reception. In addition, applying a slow attack automatic gain control (AGC) algorithm improves system sensitivity and performance. The implementation is done in MATLAB Simulink and C++. Software Defined Radio (SDR) module, BladeRF, is used programable platform for the communication system. Subsequently, the lab experimental and flight test results show that when applying these strategies in a real environment, significant performance is achievable.},

abstract = {In the Internet of Things (IoT) era, the surge in Machine-Type Devices (MTDs) has introduced 

Massive IoT (MIoT), opening new horizons in the world of connected devices. However, such 

proliferation presents challenges, especially in storing and analyzing massive, heterogeneous data 

streams in real time. In order to manage Massive IoT data streams, we utilize analytical database 

software such as Apache Druid version 28.0.0 that excels in real-time data processing. Our approach 

relies on a publish/subscribe mechanism, where device-generated data are relayed to a dedicated 

broker, effectively functioning as a separate server. This broker enables any application to subscribe to 

the dataset, promoting a dynamic and responsive data ecosystem. At the core of our data transmission 

infrastructure lies Apache Kafka version 3.6.1, renowned for its exceptional data flow management 

performance. Kafka efficiently bridges the gap between MIoT sensors and brokers, enabling parallel 

clusters of brokers that lead to more scalability. In our pursuit of uninterrupted connectivity, we 

incorporate a fail-safe mechanism with two Software-Defined Radios (SDR) called Nutaq PicoLTE 

Release 1.5 within our model. This strategic redundancy enhances data transmission availability, 

safeguarding against connectivity disruptions. Furthermore, to enhance the data repository security, 

we utilize blockchain technology, specifically Hyperledger Fabric, known for its high-performance 

attributes, ensuring data integrity, immutability, and security. Our latency results demonstrate that 

our platform effectively reduces latency for 100,000 devices, qualifying as an MIoT, to less than 

25 milliseconds. Furthermore, our findings on blockchain performance underscore our model as a secure 

platform, achieving over 800 Transactions Per Second in a dataset comprising 14,000 transactions, 

thereby demonstrating its high efficiency.},

abstract = {In the next generation modernization plan, the automatic dependent surveillance-broadcast (ADS-B) system plays a pivotal role. However, the ADS-B's low level of security and its vulnerabilities have raised valid concerns. The main objectives of this paper are to highlight the limitations of legacy ADS-B systems and to assess the feasibility of using Format-preserving (F), Feistel-based encryption (F), with multiple implementation variances (X) (FFX) algorithms, for enhancing ADS-B's security. The offered solution is implemented in a standard software-defined radio (SDR) ADS-B to be utilized in real-time applications. Furthermore, a new proposed blockchain scheme is used as a secured database to manage the cipher key. The metric of message entropy is used to assess an algorithm's ability to confuse and diffuse predictable ADS-B messages; correlation and serial correlation of plain data and cipher data are deployed to evaluate the proposed method's security level. The authors provide both MATLAB simulations and flight test outcomes to demonstrate the feasibility of this approach. Based on our security analysis, ADS-B information can be kept confidential through our scheme. The performance evaluation results reveal that the proposed scheme is achievable, compatible, and efficient for the avionics industry},

abstract = {The Unmanned Aerial Vehicle (UAV) is one of the most remarkable inventions of the last 100 years. Much research has been invested in the development of this flying robot. The landing system is one of the more challenging aspects of this system's development. Artificial Intelligence (AI) has become the preferred technique for landing system development, including reinforcement learning. However, current research is more focused is on system development based on image processing and advanced geometry. A novel calibration based on our previous research had been used to ameliorate the accuracy of the AprilTag pose estimation. With the help of advanced geometry from camera and range sensor data, a process known as Inverse Homography Range Camera Fusion (IHRCF), a pose estimation that outperforms our previous work, is now possible. The range sensor used here is a Time of Flight (ToF) sensor, but the algorithm can be used with any range sensor. First, images are captured by the image acquisition device, a monocular camera. Next, the corners of the landing landmark are detected through AprilTag detection algorithms (ATDA). The pixel correspondence between the image and the range sensor is then calculated via the calibration data. In the succeeding phase, the planar homography between the real-world locations of sensor data and their obtained pixel coordinates is calculated. In the next phase, the pixel coordinates of the AprilTag-detected four corners are transformed by inverse planar homography from pixel coordinates to world coordinates in the camera frame. Finally, knowing the world frame corner points of the AprilTag, rigid body transformation can be used to create the pose data. A CoppeliaSim simulation environment was used to evaluate the IHRCF algorithm, and the test was implemented in real-time Software-in-the-Loop (SIL). The IHRCF algorithm outperformed the AprilTag-only detection approach significantly in both translational and rotational terms. To conclude, the conventional landmark detection algorithm can be ameliorated by incorporating sensor fusion for cameras with lower radial distortion.},

abstract = {Accurate geolocation and tracking of Radio-Frequency Interference (RFI) sources, which 

affect wireless and satellite systems such as Global Navigation Satellite Systems (GNSS) and Satellite 

Communication (SatCom) systems, are considered to be a significant issue. Several studies connected 

to civil and military operations on this issue have been investigated recently. The literature review has 

surveyed many algorithm simulations for optimizing geolocation and target-tracking estimation. Al- 

though most of these algorithms have their own advantages, they have weaknesses, such as accuracy, 

mathematical complexity, difficulties in implementation, and validation in the real environment, etc. 

This study has been concerned with investigating the accuracy of geolocation and tracking under high 

speed and powerful rotation using extracted data from the Orolia Skydel simulator, which simulates 

the space environment involving Low Earth Orbit (LEO) satellites as sensors and Unmanned Aerial 

Vehicles (UAV) as RFI emitters. Various scenarios modeled using the Orolia Simulator for quasi-real 

dynamic trajectories of LEO satellites have been created. The assumed approaches have been verified 

by Cramer-Rao Lower Bound (CRLB) and Posterior CRLB (PCRLB) to determine the increase in 

Root Mean Square Error (RMSE) value. The simulation scenarios have been performed using the 

Monte Carlo iteration. Eventually, the overall achieved results of the considered approaches using 

data acquired from the Orolia Simulator were presented and compared with theoretical simulation},

abstract = {The removal filter coefficients in this technique are dependent on the jammer's power and its Instantaneous Frequency (IF) information, which can both be obtained in the time-frequency domain (adaptive filtering techniques). The dependence of the removing/reducing filter characteristics on the interference power is critical, as it allows an optimal trade-off between removal interference and the amount of self-noise generated by the filter. This trade-off is bounded by the two extreme cases of no notch filter (no self-noise) and full suppression (k1 = 1) for both low- and high-power jammer values. In this paper, a cascade second-order adaptive direct Infinite Impulse Response (IIR) Notch Filter (NF) with a gradient-based algorithm to suppress the Continuous-Wave (CW and MCW) interference is proposed for maximizing the receiver Signal-to-Noise Ratio (SNR) in a Quadrature Phase-Shift Keying (QPSK)-modulated signal. The suppression approach consists of two Adaptive IIR NFs (ANFs) based on a direct-form structure: the Hd1(z) and Hd1(z). The proposal in this work presents a low-complexity Time-Domain (TD) algorithm for controlling the update filter coefficient and notch depth. Simulation results demonstrate that the proposed approach represents an effective method for removing/reducing the impacts of CWI/MCWI, resulting in improved system performance for low- and high-power jammer values when compared with the case of full suppression (k1 = 1); furthermore, it also improves the notch filter's output SNR for a given Jamming-to-Signal Ratio (JSR) value and Bit Error Ratio (BER) performance. For example, the SNR output of the proposed IIR NF was enhanced by 7 dB versus the case without a filter when Eb/No = 15 dB and JSR = ?5 dB. The proposed method can detect and mitigate weak and strong jamming with JSR values ranging from ?30 to 40 dB, and can track the hopping frequency interference. Moreover, an improved BER performance is seen as compared to the case without an IIR NF.},

abstract = {Much research has been accomplished in the area of drone landing and specifically pose 

estimation. While some of these works focus on sensor fusion using GPS, or GNSS, we propose 

a method that uses sensors, including four Time of Flight (ToF) range sensors and a monocular 

camera. However, when the descending platform is unstable, for example, on ships in the ocean, 

the uncertainty will grow, and the tracking will fail easily. We designed an algorithm that includes 

four ToF sensors for calibration and one for pose estimation. The landing process was divided into 

two main parts, the rendezvous and the final landing. Two important assumptions were made for 

these two phases. During the rendezvous, the landing platform movement can be ignored, while 

during the landing phase, the drone is assumed to be stable and waiting for the best time to land. 

The current research modifies the landing part as a stable drone and an unstable landing platform, 

which is a Stewart platform, with a mounted AprilTag. A novel algorithm for calibration was used 

based on color thresholding, a convex hull, and centroid extraction. Next, using the homogeneous 

coordinate equations of the sensors' touching points, the focal length in the X and Y directions can be 

calculated. In addition, knowing the plane equation allows the Z coordinates of the landmark points 

to be projected. The homogeneous coordinate equation was then used to obtain the landmark's X 

and Y Cartesian coordinates. Finally, 3D rigid body transformation is engaged to project the landing 

platform transformation in the camera frame. The test bench used Software-in-the-Loop (SIL) to 

confirm the practicality of the method. The results of this work are promising for unstable landing 

platform pose estimation and offer a significant improvement over the single-camera pose estimation 

AprilTag detection algorithms (ATDA).},

abstract = {Radio Frequency Interferences (RFI), such as strong Continuous Wave Interferences (CWI), can influence the Quality of Service (QoS) of communications, increasing the Bit Error Rate (BER) and decreasing the Signal-to-Noise Ratio (SNR) in any wireless transmission, including in a Digital Video Broadcasting (DVB-S2) receiver. Therefore, this paper presents an algorithm for detecting and mitigating a Multi-tone Continuous Wave Interference (MCWI) using a Multiple Adaptive Notch Filter (MANF), based on the lattice form structure. The Adaptive Notch Filter (ANF) is constructed using the second-order IIR NF. The approach consists in developing a robust low-complexity algorithm for removing unknown MCWI. The MANF model is a multistage model, with each stage consisting of two ANFs: the adaptive IIR notch filter Hl(z) and the adaptive IIR notch filter HN(z), which can detect and mitigate CWI. In this model, the ANF is used for estimating the Jamming-to-Signal Ratio (JSR) and the frequency of the interference (w(0)) by using an LMS-based algorithm. The depth of the notch is then adjusted based on the estimation of the JSR. In contrast, the ANF HN(z) is used to mitigate the CW interference. Simulation results show that the proposed ANF is an effective method for eliminating/reducing the effects of MCWI, and yields better system performance than full suppression (kN=1) for low JSR values, and mostly the same performance for high JSR values. Moreover, the proposed can detect low and high JSR and track hopping frequency interference and provides better Bit error ratio (BER) performance compared to the case without an IIR notch filter.},

abstract = {With the emergence of numerous low Earth orbit (LEO) satellite constellations such as 

Iridium-Next, Globalstar, Orbcomm, Starlink, and OneWeb, the idea of considering their downlink 

signals as a source of pseudorange and pseudorange rate measurements has become incredibly 

attractive to the community. LEO satellites could be a reliable alternative for environments or 

situations in which the global navigation satellite system (GNSS) is blocked or inaccessible. In this 

article, we present a novel in-flight alignment method for a strapdown inertial navigation system 

(SINS) using Doppler shift measurements obtained from single or multi-constellation LEO satellites 

and a rotation technique applied on the inertial measurement unit (IMU). Firstly, a regular Doppler 

positioning algorithm based on the extended Kalman filter (EKF) calculates states of the receiver. This 

system is considered as a slave block. In parallel, a master INS estimates the position, velocity, and 

attitude of the system. Secondly, the linearized state space model of the INS errors is formulated. The 

alignment model accounts for obtaining the errors of the INS by a Kalman filter. The measurements 

of this system are the difference in the outputs from the master and slave systems. Thirdly, as the 

observability rank of the system is not sufficient for estimating all the parameters, a discrete dual-axis 

IMU rotation sequence was simulated. By increasing the observability rank of the system, all the 

states were estimated. Two experiments were performed with different overhead satellites and 

numbers of constellations: one for a ground vehicle and another for a small flight vehicle. Finally, the 

results showed a significant improvement compared to stand-alone INS and the regular Doppler 

positioning method. The error of the ground test reached around 26 m. This error for the flight test 

was demonstrated in different time intervals from the starting point of the trajectory. The proposed 

method showed a 180% accuracy improvement compared to the Doppler positioning method for up 

to 4.5 min after blocking the GNSS.},

abstract = {Radio Frequency Interference (RFI) detection and characterization play a critical role in ensuring the security of all wireless communication networks. Advances in Machine Learning (ML) have led to the deployment of many robust techniques dealing with various types of RFI. To sidestep an unavoidable complicated feature extraction step in ML, we propose an efficient Deep Learning (DL)-based methodology using transfer learning to determine both the type of received signals and their modulation type. To this end, the scalogram of the received signals is used as the input of the pretrained convolutional neural networks (CNN), followed by a fully-connected classifier. This study considers a digital video stream as the signal of interest (SoI), transmitted in a real-time satellite-to-ground communication using DVB-S2 standards. To create the RFI dataset, the SoI is combined with three well-known jammers namely, continuous-wave interference (CWI), multi- continuous-wave interference (MCWI), and chirp interference (CI). This study investigated four well-known pretrained CNN architectures, namely, AlexNet, VGG-16, GoogleNet, and ResNet-18, for the feature extraction to recognize the visual RFI patterns directly from pixel images with minimal preprocessing. Moreover, the robustness of the proposed classifiers is evaluated by the data generated at different signal to noise ratios (SNR)},

abstract = {The Quality of Service (QoS) and security of Satellite Communication (Satcom) are crucial as Satcom plays a significant role in a wide range of applications, such as direct broadcast satellite, earth observation, navigation, and government/military systems. Therefore, it is necessary to ensure that transmissions are incorruptible, particularly in the presence of challenges such as Radio Frequency Interference (RFI), which is of primary concern for the efficiency of communications. The security of a wireless communication system can be improved using a robust RFI detection method, which could, in turn, lead to an effective mitigation process. This paper presents a new method to recognize received signal characteristics using a hierarchical classification in a multi-layer perceptron (MLP) neural network. The considered characteristics are signal modulation and the type of RFI. In the experiments, a real-time video stream transmitted in the direct broadcast satellite is utilized with four modulation types, namely, QPSK, 8APSK, 16APSK, and 32APSK. Moreover, it is assumed that the communication signal can be combined with one of the three significant types of interference, namely, Continuous Wave Interference (CWI), Multiple CWI (MCWI), and Chirp Interference (CI). In addition, two robust feature selection techniques have been developed to select more informative features, which leads to improving the classification precision. Furthermore, the robustness of the trained techniques is assessed to predict unknown signals at different Signal to Noise Ratios (SNRs).},

The CD approach has been proposed because of its potential to operate as both a direct positioning method and a high-sensitivity acquisition method. This paper is dedicated to the development of a new CD architecture for processing satellite signals in challenging environments. It proposes the best signal acquisition method used according to the reception conditions of the different receivers that can assist the user in difficulty. Knowing that the CD approach is beneficial in the case where the maximum of satellite signals can be combined, the proposed approach consists in choosing the best receiver(s) from several connected receivers to serve as a reference station, as smart cooperative navigation concept. New metrics of the CD with optimal weighting of visible satellites are exploited. Analysis of optimization method in order to use better satellites according to some defined parameters (elevation, C/N0 , and GDOP) were carried out. Real GPS L1 C/A signals are exploited to analyze the efficiency of the proposed approach. A comparison of the results through the accumulation of some good satellites among all visible satellites have shown the effectiveness of this method.},

abstract = {Using multiple IMUs allows both their distribution along vehicle structures and a reliance on integration methods, which is not possible with a single IMU. This paper addresses the issue of relying on three IMUs instead of only one of a higher quality in the context of a satellite launcher. The impact of the IMU positions was tested by comparing collocated IMUs against IMUs installed in the head of each launcher stage. For multi-IMU configurations, three integration methods were tested: all IMUs fused in a single INS, multiple INSs fused in a stacked filter, and multiple INSs fused in a stacked filter with geometrical constraints. All navigation solutions were aided by a three-axis attitude reference sensor and were tested with and without a GPS receiver. The results show that distributing IMUs along the launcher structure does not improve navigation performances compared to having them collocated. The fusion of multiple IMUs in one INS provides equivalent results as one IMU. However, fusing multiple INSs greatly reduces estimation errors. Performances are further improved with the addition of geometrical constraints. During long GPS outages, relative velocity and position constraints should not be exploited, as they may lead to filter divergence.},

abstract = {Nowadays, civil Global Navigation Satellite System (GNSS) signals are available in both L1 and L5 bands. A receiver does not need to acquire independently the signals in both bands coming from a same satellite, since their carrier Doppler and code delay are closely related. Therefore, the question of which one to acquire first rises naturally. Although the common thought would tell the L1 band signals which are narrowband, an accurate comparison has never been done, and the decision is not as easy as it seems. Indeed, L5 band signals have several advantages such as stronger power, lower carrier Doppler, or a pilot channel, unlike the Global Positioning System (GPS) L1 C/A signal. The goal of this paper is therefore to compare the acquisition of L1 and L5 bands signals (GPS L1 C/A and L5, Galileo E1 and E5a/b) to determine which one is more complex and by which factor, in terms of processing time and memory, considering hardware receivers and the parallel code search. The results show that overall the L5 band signals are more complex to acquire, but it depends strongly on the conditions. The E5 signal is always more complex to acquire than E1, while the L5 signal can have a complexity close to the L1 C/A in some cases. Moreover, precise assistance providing accurate Doppler could significantly reduce the L5 complexity below the L1 complexity.},

abstract = {Substantial changes have occurred in the Information Technology (IT) sectors and with these changes, the demand for remote access to field sensor information has increased. This allows visualization, monitoring, and control through various electronic devices, such as laptops, tablets, i-Pads, PCs, and cellular phones. The smart phone is considered as a more reliable, faster and efficient device to access and monitor industrial systems and their corresponding information interfaces anywhere and anytime. This study describes the deployment of a protocol whereby industrial system information can be securely accessed by cellular phones via a Supervisory Control And Data Acquisition (SCADA) server. To achieve the study goals, proprietary protocol interconnectivity with non-proprietary protocols and the usage of interconnectivity services are considered in detail. They support the visualization of the SCADA system information, and the related operations through smart phones. The intelligent sensors are configured and designated to process real information via cellular phones by employing information exchange services between the proprietary protocol and non-proprietary protocols. SCADA cellular access raises the issue of security flaws. For these challenges, a cryptography-based security method is considered and deployed, and it could be considered as a part of a proprietary protocol. Subsequently, transmission flows from the smart phones through a cellular network.},

abstract = {This paper presents a universal GNSS receiver channel capable of tracking any civil GNSS signal. This fundamentally differs from dedicated channels, each customized for a given signal. A mobile device could integrate fewer universal channels to harvest all available signals. This would allow securing signal availability, while minimizing power consumption and chip size, thus maximizing battery lifetime. In fact, the universal channel allows sequential acquisition and tracking of any chipping rate, carrier frequency, FDMA channel, modulation, or constellation, and is totally configurable (any integration time, any discriminator, etc.). It can switch from one signal to another in 1.07 ms, making it possible for the receiver to rapidly adapt to its sensed environment. All this would consume 3.5 mW/channel in an ASIC implementation, i.e., with a slight overhead compared to the original GPS L1 C/A dedicated channel from which it was derived. After extensive surveys on GNSS signals and tracking channels, this paper details the implementation strategies that led to the proposed universal channel architecture. Validation is achieved using GNSS signals issued from different constellations, frequency bands, modulations and spreading code schemes. A discussion on acquisition approaches and conclusive remarks follow, which open up a new signal selection challenge, rather than satellite selection.},

abstract = {Target positioning systems based on MEMS gyros and laser rangefinders (LRs) have extensive prospects due to their advantages of low cost, small size and easy realization. The target positioning accuracy is mainly determined by the LR's attitude derived by the gyros. However, the attitude error is large due to the inherent noises from isolated MEMS gyros. In this paper, both accelerometer/magnetometer and LR attitude aiding systems are introduced to aid MEMS gyros. A no-reset Federated Kalman Filter (FKF) is employed, which consists of two local Kalman Filters (KF) and a Master Filter (MF). The local KFs are designed by using the Direction Cosine Matrix (DCM)-based dynamic equations and the measurements from the two aiding systems. The KFs can estimate the attitude simultaneously to limit the attitude errors resulting from the gyros. Then, the MF fuses the redundant attitude estimates to yield globally optimal estimates. Simulation and experimental results demonstrate that the FKF-based system can improve the target positioning accuracy effectively and allow for good fault-tolerant capability.},

abstract = {This paper presents modification of Radial Basis Function Artificial Neural Network (RBF ANN)-based temperature compensation models for Interferometric Fiber Optical Gyroscopes (IFOGs). Based on the mathematical expression of IFOG output, three temperature relevant terms are extracted, which include: (1) temperature of fiber loops; (2) temperature variation of fiber loops; (3) temperature product term of fiber loops. Then, the input-modified RBF ANN-based temperature compensation scheme is established, in which temperature relevant terms are transferred to train the RBF ANN. Experimental temperature tests are conducted and sufficient data are collected and post-processed to form the novel RBF ANN. Finally, we apply the modified RBF ANN based on temperature compensation model in two IFOGs with temperature compensation capabilities. The experimental results show the proposed temperature compensation model could efficiently reduce the influence of environment temperature on the output of IFOG, and exhibit a better temperature compensation performance than conventional scheme without proposed improvements.},

By analyzing the accuracy and reliability characteristics of an inertial navigation system (INS), criteria for redundant configuration design are introduced. Then the orthogonal rotation configuration is formed through a two-rotation of a set of orthogonal inertial sensors around a space vector. A feasible installation method is given for the real engineering realization of this proposed configuration. The performances of the novel configuration and another six configurations are comprehensively compared and analyzed. Simulation and experimentation are also conducted, and the results show that the orthogonal rotation configuration has the best reliability, accuracy and fault detection and isolation (FDI) performance when the number of gyros is nine.},
