With the development and breakthrough of the ADC/DAC, digital signal processing/processor, and other related technologies, Software Defined Radio (SDR) has become one of the most important trends for the aviation industry, and is one of the main components for the Next Generation Air Transportation System. At LASSENA, under the project codename AVIO-505, different aspects, advantages/drawbacks of the SDR in avionics have been investigated, and many promising results have been obtained. The Software Defined Avionic Radio (SDAR) approach, on the one way, can achieve the standard requirements for the equivalent currently in use avionic. On the other hand, SDAR offers a highly integrated solution for the future avionic architecture, and at the same time improve the Size, Weight, Power, and Cost of the systems and optimizing the footprint. For the next phase of this project, besides the developed/integrated and developing avionics (such as VOR, ILS, ADS-B, DME, UAT, ELT, etc.), RxGNSS (including GPS, Galileo, GLONASS will be one of the main targets. A highly integrated system of RxGNSS and SDAR not only can have the benefits of components reduction/optimization but can also be the key for other applications in the future. The student participates in this project, on the one hand, will have the opportunity to work with state-of-the-art materials in the field, including the currently SDAR and the RxGNSS receiver of LASSENA. At the same time, he/she will learn about the principles, the standards, as well as the requirements of the target systems, and will work with not only C/C++ and Python for the embedded systems but also Verilog/VHDL for the FPGA.
