The AVIO-505 Project aimed to establish new design methods and digital signal processing techniques for robust and efficient universal Communication, Navigation and Surveillance (CNS) equipment in aviation and aerospace, in general. The Multiple Inputs/Multiple Outputs Software Defined Radio (MIMO-SDR), one of the most important achievements of the project, enables the capability to redeploy functionality based on the current phase of a flight while minimizing connectors, antennas, cables length, EMI (electromagnetic interference) and overall system footprint. This new architecture and concept will open new horizons for new applications, not only for current international civil and military aircrafts, but also future UAVs and new satellites with novel applications. In the Phase II of the project, the LASSENA will continue on this promising research and propel SDR avionics to certification, flight testing and commercialization.
Great thanks to ALL our partners, collaborators, and all the +60 HQP trained students for their active participation in this project!

Congratulations,Neda Navidi! Best Paper Award in ICCSTE 2017.
Congratulations to Mme. Neda Navidi who was presented the Best Paper Award in ICCSTE 2017 (Vancouve,Canada,August 7-8,2017).
Mme. Neda Navidi is a PhD student under the supervision of Prof. Rene Jr Landry, and the paper rewarded is "Location Detection of Vehicular Accident Using Global Navigation Satellite Systems/Inertial Measurement Units Navigator". The main goal of this paper is to detect the location of a car accident by combining different methods. The methods, which are considered in this paper, are Global Navigation Satellite Systems/Inertial Measurement Units (GNSS/IMU)-based navigation and vehicle accident detection algorithms. They are expressed by a set of raw measurements, which are obtained from a designed integrator black box using GNSS and inertial sensors. Another concern of this paper is the definition of accident detection algorithm based on its jerk to identify the position of that accident. In fact, the results convinced us that, even in GNSS blockage areas, the position of the accident could be detected by GNSS/INS integration with 50% improvement compared to GNSS stand alone.
The ICCSTE 2017(19th International Conference on Control Systems and Transportation Engineering ) is the premier interdisciplinary platform for the presentation of new advances and research results in the fields of Control Systems and Transportation Engineering. The conference will bring together leading academic scientists, researchers and scholars in the domain of interest from around the world.

Performance improvements of a navigation algorithm INS / GPS low cost used in urban areas
To provide a solution robust and accurate navigation , GPS receivers must operate in optimal conditions , that is to say have a direct line of sight with at least four satellites, which is hard to find in an urban environment where GPS signals may be contaminated with significant multipath errors . Coupling GPS data with those from an inertial navigation system (INS) can significantly reduce these errors, however, this technique is generally valid for high-end systems. Indeed, for systems with low cost inertial sensors used generally have significant measurement errors causing a rapid divergence of the navigation solution . There is a real need for the development of new technologies that enable self calibration of inertial sensors at low cost.
The objective of this project is to improve the performance of integrated navigation systems INS / GPS low cost based on the use of inertial MEMS sensors to enable an accurate and robust positioning in urban environment .
For this , this paper proposes the following methodology:
1) Development of a robust calibration procedure for real-time error compensation deterministic
2) Error Compensation stochastic nature of low-cost inertial sensors using a Gauss- Markov model (GM ) based on the parameter of the autoregressive (AR) model

Marinvent and ETS successfully develop a wireless prototyping process for Marinvent’s APM through Engage project
Montreal, Quebec, Monday, April 8, 2013 – Marinvent announces today the successful completion of its Airfoil Performance Monitor (APM)-Engage project. The project, recently completed in collaboration with École de technologie supérieure (ETS), has been a huge success and has demonstrated the intrinsic value of strong partnerships between Small & Medium Enterprises (SMEs) like Marinvent and research institutions like ETS. The result of the project is the successful development of a rapid prototyping process for Marinvent’s APM through the use of wireless APM mast technology.
The Marinvent-ETS team has been able to develop, deploy and successfully demonstrate wireless data transmission from a small, battery powered, APM mast assembly deployed on the wing of Marinvent’s Piaggio Avanti aircraft to a cockpit-based receiver located in the aircraft cockpit.
“This is a major accomplishment as it now enables, for the first time, the deployment of our APM system for testing and evaluation purposes on aircraft without the costly and time-consuming need to drill holes,” said Phil Cole, VP Business Development at Marinvent Corporation. “We are very pleased with the way the ETS team worked with us on this project and the results we were jointly able to achieve in a relatively short time period. We have already identified areas of continued collaboration with ETS on this research, and foresee continued close cooperation on APM, training and other projects in the near future.”
“Within a 6 months project, the team was able to develop proper software and to embed in the Marinvent APM a tiny full duplex radio, 2 analog to digital converters with low power supply electronic. The resulting embedded APM could now work autonomously and could contain 2 pressure sensors (back and front sides) with all combined previous electronic, simplifying considerably testing and certification procedures.”, said René Jr. Landry, teacher at ETS and Director of LASSENA (Laboratory of Specialized Embedded System, Navigation and Avionic).

Software radios for highly integrated system architecture
The project aims at establishing new methods and techniques of processing of the digital signals for universal effective and strong plans of navigation and communication in the aeronautical and aerospace domains. New standards in avionics are in study and several arguments are in favour of the adoption of the software radio. This project aims at the integration of multiple systems of navigation and communication in a unique equipment minimizing the busy space, at the weight of the avionics, the number of rooms(parts,plays) and incorporating new more effective management systems of the air space ( ADS-B), the everything guarantor directly in the international programs of reduction of greenhouse gases ( GES). The aeronautical / aerospace industry asks for a new approach by using a single generic system, reprogrammable and universal replacing the multiple radios and the present antennas on a plane. The new system will allow a simultaneity of functioning of several systems on a platform of flexible development and intended for the future applications. The project will handle with the integration of the systems DME, transponder Mode S and of a radio wide band, inside software architecture getting closer to the antenna. This architecture will allow the redeployment at request of features according to the phase of the flight, and the minimization of the electromagnetic interferences, the length of cables, and number of connectors and antennas. The idea being to convert the signals RF to the antenna and to transmit them in basic band towards the generic radio for the digital processing. The prototype will be estimated in laboratory by simulations and during flight using a specialized bench test supplying conditions of operation real and allowing to validate the performance of protocols with the real infrastructures systems and aeronautics. The project will contribute to the international community by defining new avionic standards, will pursue the efforts of Canada in the reduction of the GES and will create new high-technology uses. The developed technologies can apply to infrastructures grounds or airborne.

Mister Guillaume Lamontagne takes successfully his master’s degree in electric engineering
Mister Guillaume Lamontagne passed successfully his oral defense within the framework of his master’s degree in electric engineering. Under the supervision of professors Landry and Kouki, the report of mister Lamontagne’s master’s degree is entitled: "conception and implementation of a head of reception with direct sampling RF for the signals of radio navigation by satellites. ". Congratulations to mister Lamontage for this beautiful realization and the recommendation of the members of the jury at the prize of the administrative council of the ÉTS.
A group of professors of the Laboratory of communications and integration of the microelectronics ( LACIME) of the ÉTS collaborated in the conception of a new sub-system of insulation against the vibrations in microgravity ( MVIS) with the Canadian Space agency. The MVIS produces a magnetic field capable of maintaining in suspension a packaging of average size inside which diverse scientific experiments can be made. This device was aboard the shuttle Atlantis which took off last February and was settled in the international Space station The noise and the vibrations are important inside this station. The systems of ventilation, the mooring of space vehicles and the work of the astronauts sometimes make vibrate the orbital complex of research. These vibrations can damage scientific experiments dedicated to the study of the effects of the microgravity. The MVIS allows to avoid that the experiments undergo these harmful effects. When it will be settled in the station, the experiments led inside the new device, as those who concern the flow of the fluids, the growth of crystals and the development of metallic alloys, will not be any more submitted to the shocks and to the vibrations.To control electromagnets generating the magnetic field of the MVIS, it was necessary to be able to sample the signal of accelerometers very precisely. It is of what made a success the researchers of the LACIME by working out digital analog converters of extreme precision for the MIVS. The previous MVIS had a dynamic range of 100 decibels, while the new covers 140 decibels. Within the framework of this research, professors Jean Belzile, François Gagnon and Naïm K. Batani, of the Department of electric engineering, applied for the patent High-Precision Digital to Analog Converter. Professor Ammar B . Kouki, René Jr Landry and Claude Thibeault also participated in the research works.
