The transponder design method and validation applicable to multi-satellites parallel testing

摘要:

为了提高星座的测试效率、降低测试成本，提出一种适合多星并行测试的应答机设计方法，通过地面测试设备和星上测控应答机复用星上的遥控 RS422 接口、遥测 RS422 接口的方式，突破了多星并行测试的瓶颈。新方法已经成功应用于某卫星星座的并行测试，降低了测试成本、提高了测试效率、缩短了星座的测试周期。

Abstract:

In this paper, a new transponder design method suitable for multi-satellites parallel testing is proposed to improve the test efficiency and to reduce the test cost. The bottleneck problem of multi-satellites parallel test is solved by the ground testing equipment and transponder using the same interface of tele-command RS422 and the interface of telemetry RS422. It has been successfully applied to the parallel testing of a constellation, which reduces the testing cost, improves the testing efficiency and shortens the testing cycle of the constellation.
