Research On The Ground Attitude Simulation Light Source Control System

Simulation is an essential step in the development of the satellite control system.At present, the main means of satellite simulation is still semi physical simulation. Satellite in outer space rely on the earth, the sun and stars as the target to determine their own attitude, measurement by using the earth sensor, solar sensor and star sensor. Therefore, in the semi physical simulation experiment, must have the corresponding light source simulation equipment for these sensors.Infrared earth sensor and solar sensor are important parts in the attitude measurement system of the synchronous spin meteorological satellite.Satellite control system in this paper have one solar sensor and two earth sensors, in the whole satellite AIT test and the field test, the light is required for the test.The spin excitation light source for the synchronous spin meteorological satellite is simulated by the combination of a small solar simulator and two miniature earth simulators, to do the ground calibration and testing. The research on a kind of advanced ground attitude simulation light source control system for satellite ground calibration experiment. Have important significance on satellite key parts quality assessment, performance testing, calibration and production. The control system research in this paper with strict timing requirements, can do the satellite spin simulation test in the case of different rotation speed.
