René Jr. Landry and Embedded Systems
Embedded systems, or independent software and electronic systems that use limited mobility resources, are widely utilized in the transportation industry. To respond to growing needs, ÉTS hosts a research group in embedded systems for aerospace. It is headed by René Jr. Landry, professor in the Department of Electrical Engineering.
When Research Develops Civilian and Military Embedded Systems
Professor Landry’s work is oriented towards solving real problems that are found in the industry. His LASSENA laboratory is composed of nearly 50 researchers and university students of all levels who work on space, sky and ground applications in both the civilian and military sectors. All their projects involve embedded systems.
The Challenge of Embedded Systems: Limited Resources
With embedded systems, the challenge is always to “do more with less” at the lowest possible cost. As these systems do not offer much programming freedom, developers must employ resource-efficient strategies in order to maximize functionality with what’s available, using limited algorithms and sensors.
Embedded Systems: Example of Aerospace Application
The LASSENA, the Canadian Space Agency and MDA are working on a revolutionary miniature embedded system for collecting environmental data, thanks to Radarsat signals and satellites.
Embedded Systems: A Sample Aerospace Application
In an aircraft, several kilometres of cables are used in the avionics and communications systems. One research project that is underway consists of combining all of these functionalities into a single system, called software-defined radio (SDR) that can be programmed according to the phases of flight.
Embedded Systems: Sample Land Applications
Professor Landry is especially interested in navigation within GPS-denied environments such as building interiors, dense downtown areas, tunnels and forests. The objective is to develop technologies that will circumvent these limitations.
His teams were involved in the development of the Ajusto software used by Desjardins Insurance, which is a vehicle monitoring and driving diagnostic system that, when installed in a vehicle, allows the behaviour of the driver to be studied. Since introducing this software, his teams have been working to develop a black box that is capable of measuring driving behaviour with precision and analyzing accidents.
