Abstract

The invention discloses an electric simulator for a star sensor, relates to an electric simulator for on-star equipment, and solves the problem that the conventional equipment or device cannot meet the requirement that the electric simulator of the star sensor and the star sensor are connected to a satellite test system simultaneously. The electric simulator comprises a functional simulation module, a simulator data interface circuit and a power supply input interface circuit, and also comprises a signal processing module, an on-star equipment data interface circuit and a power supply output interface circuit; an analog sensitive data signal output by the functional simulation module and a star sensitive data signal output by the on-star equipment data interface circuit are subjected to isolation synthesis processing in the signal processing module; the processed signal output end of the signal processing module is connected with the processed signal input end of the simulator data interface circuit; and the voltage output end of the power supply input interface circuit is connected with the voltage input end of the power supply output interface circuit. The electric simulator ensures that the electric simulator of the star sensor and the star sensor are connected to the satellite test system simultaneously, and is used for a satellite attitude control system or an entire star test.

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...
