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）将通过稳健和优化的架构，设计、开发和集成软件定义航空电子模块（SDAM）到单个硬件单元中。为此，该项目将基于先前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（泰雷兹、ACSS、加拿大SII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，同时与IMA（集成模块化航空电子）等现代航空电子架构兼容。这项新设计将涵盖现代化的航空电子设备功能，如VHF全向测距（VOR）、仪表着陆系统（ILS）、战术空中导航（TACAN）、距离测量设备（DME）、广播自动相关监视（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和新颖多频段天线设计的全集成多模SDAR将在独特的集成航空电子网络架构中完成。为了验证，将在整个项目中计划和安排各种各样的测试，包括飞行测试。我们面临的挑战是设计未来的SDAR架构，不仅要有效地处理多个关键功能，还要具备一些高级功能，如信号完整性监控、认证算法、降级缓解和容错能力，同时保持最小的尺寸、重量、功耗和成本（SWaP-C）要求。该项目的主要成果是为机载CNS航空电子系统提供创新的高度集成解决方案，最终将大大减少现代飞机的电缆长度和组件数量。另外，它可以很容易地适应应付潜在的航空标准变化或装配到无人驾驶飞行器（uav）。

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).
