提出了一种基于DSP的星载定标器地检设备的设计与实现。以DSP为主控单元,辅以USB通讯模块、RS-422串行通讯模块、三线制串行通讯模块、模拟量 采集模块、OC驱动模块等实现了地检设备的研制,利用该地检设备完成了星上定标器电子学接口的测试,对地检设备的功能及性能进行了验证。

A design of ground test equipment for ratioing calibrator on board based on DSP chip was proposed and implemented. DSP was utilized as the core processor with upper computer communication module, lower computer RS-422 serial communication module, three wires serial communication module, analog signal acquisition module and OC drive modular. The equipment has been succeed in testing mulit-interface on board calibrator, and the function, performance and stability were validated.
