Design and implementation of flight test data relay management unit

In flight test, the test data captured is transported to ground system by telemetry link for real-time monitor, and the test data needs to be proceeded before telemetry transported. Using software defined radio technology, a flight test data relay management system was designed. The key parts of unit are fully detailed, including the FPGA,hardware circuit and the embedded software. The functions of processing and transmitting flying test data and management of wireless link are designed, meeting the application requirements by means of flight test.
