适用于多星并行测试的应答机设计方法与验证

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

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。

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.
