Description

technical field [0001] The invention relates to a simulator, in particular to a code disc type solar sensor probe simulator. Background technique [0002] The satellite electrical performance testing process includes component testing, subsystem testing and whole-star testing. During each stage of testing, some auxiliary equipment or devices are needed to simulate real on-board equipment to achieve component, subsystem or whole-star testing. For the purpose of electrical performance testing, these auxiliary equipment or devices that simulate real equipment are called simulators. The simulator mainly simulates the input and output signal characteristics, communication protocols, and component characteristics of the electrical interface of the real on-board equipment. [0003] The sun sensor is a common equipment on the star. It can determine the angle between the measuring device and the sun ray by sensitive sunlight, so as to measure and determine the attitude of the satell...
