Next Generation SDR Avionics for Communication, Navigation and Surveillance

The Next Generation Software Defined Avionics Radio (SDAR) for Communication, Navigation and Surveillance (CNS) project (NextGen SDAR) is to design, develop and integrate Software Defined Avionic modules (SDAM) into a single hardware unit through a robust and optimized architecture. To do that, this project will be based on the major achievements of the previous NSERC AVIO-505 and AVIO-404 projects. In this new project, our collaboration with major avionic manufacturers (Thales, ACSS, SII Canada and Bombardier) aims to elevate and improve SDAR design and integration with readiness for a certifiable solution to the aviation market, while being compatible with modern avionic architectures such as IMA (Integrated Modular Avionics). This new design will cover modernized avionics functions such as VHF Omnidirectional Range (VOR), Instrument Landing System (ILS), Tactical Air Navigation (TACAN), Distance Measuring Equipment (DME), Automatic Dependent Surveillance – Broadcast (ADS-B) In/Out, Transponder Mode-S (TMS), Wide-Band Radio (WBR) and Radio Altimeters, as a critical system for both civilian and military. Fully integrated multimode SDAR with multi-standard RF front-end and novel multiband antenna designs will be completed in a unique integrated avionics network architecture. A large variety of tests including flight tests will be planned and scheduled all over the project for the validation. The challenge is to design the future SDAR architecture that can not only efficiently handle multiple critical functions, but also some advanced features such as signal Integrity Monitoring, authentication algorithms, degradation mitigation and fault tolerant capabilities while keeping minimum Size, Weight, Power and Cost (SWaP-C) requirements. The main outcome of the project is an innovative highly integrated solution for on-board CNS avionics systems that will eventually reduce significantly cables length and the number of components in modern aircrafts. Additionally, it could be easily adapted to cope with potential aeronautical standards changes or to be fitted to Unmanned Aerial Vehicles (UAVs).
