Application of SOQPSK modulation technology in telemetry system for flight test

Since traditional FM mode can′t satisfy the requests in the aspect of high-speed data transmission and high re liability of flight test,the SOQPSK modulation mode that has higher efficiency than FM has been used in flight test overseas.In the testing mission of a model,SOQPSK modulation mode was applied to telemetry system for flight test in China for the first time.The flight test proves that comparing with FM mode this new modulation mode can provide higher data rates and efficien cy,so it can ensure the flight test.Along with the design and research of large aircraft,this new modulation mode will be wide ly used in telemetry monitoring.
