Next Generation SDR Avionics for Communication, Navigation and Surveillance

用于通信、导航和监视(CNS)的下一代软件定义航空电子无线电(SDAR)项目(NextGen SDAR)旨在通过健壮和优化的体系结构将软件定义航空电子模块(SDAM)设计、开发和集成到单个硬件单元中。为此，该项目将基于以前NSERC Avio-505和Avio-404项目的主要成果。在这个新项目中，我们与主要航空电子制造商(泰利斯、ACSS、SII Canada和庞巴迪)的合作旨在提升和改进SDAR的设计和集成，为航空市场提供可认证的解决方案，同时兼容现代航空电子体系结构，如IMA(集成模块化航空电子)。这一新设计将涵盖现代航空电子功能，如甚高频全向范围(VOR)、仪表着陆系统(ILS)、战术空中导航(TACAN)、测距设备(DME)、自动独立监视广播(ADS-B)输入/输出、应答器模式S(TMS)、宽带无线电(WBR)和无线电高度计，作为民用和军用的关键系统。具有多标准射频前端的全集成多模SDAR和新颖的多频天线设计将在一个独特的综合航空电子网络架构中完成。包括飞行测试在内的各种测试将被计划和安排在整个项目中进行验证。挑战在于设计未来的SDAR架构，它不仅可以有效地处理多个关键功能，还可以处理一些高级功能，如信号完整性监控、身份验证算法、降级缓解和容错能力，同时保持最小尺寸、重量、功耗和成本(SWAP-C)要求。该项目的主要成果是为机载CNS航空电子系统提供一种创新的高度集成的解决方案，最终将显著减少现代飞机中的电缆长度和组件数量。此外，它可以很容易地进行改装，以应对潜在的航空标准变化或安装到无人机(UAV)上。

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).
