Description

technical field

[0001] The invention relates to an electrical simulator of on-board equipment. Background technique

[0002] The satellite electrical performance testing process includes component testing, subsystem testing and full-star testing. In the process of subsystem testing and full-star testing or in certain stages of the testing process, some auxiliary equipment or devices are needed to simulate real satellites. Equipment to achieve the purpose of sub-system or entire star electrical performance testing, these auxiliary equipment or devices that simulate real equipment are called electrical simulators. The electrical simulator mainly simulates the structure of the electrical interface of real on-board equipment, the processing of communication protocols, data flow and timing characteristics, etc.

[0003] The electrical interface of the electrical simulator of the on-board equipment is completely consistent with the electrical interface of the simulated on-board e...
