Semi-physical simulation of attitude control system is the more synthetically test and verify for designing of small satellite control system. It is an important means of small satellite development. However  the results of current semi-physical simulation system have a lot of non-intuitive. Compare with the actual environment  the simulation environment still has striking disparity. So the shortcomings affect precision of simulation. Based on the virtual display technology  the group semi-physical simulation system has been constructed for attitude control of small satellite due to the combination with xPC real-time environment  the simulation computer  high-precision single-axis air-bearing turntable  reaction wheel  air thrust device  fiber gyroscopes  sensors synchronizer  power subsystem and wireless devices virtual display computer etc. Semi-physical simulation achieved the visual simulation in orbit and tracked new information of virtual environment of space into real-time simulation computer. Simulation results show that the simulation system for real-time attitude and orbit position of small satellite semi-physical simulation has an excellent display effect. At the same time  Real-time transfuse of orbit information provides a more accurate space environment simulation. The simulation system of small satellite attitude control to design and evaluate the more direct and convenient. (2012) Trans Tech Publications  Switzerland.

The solar irradiance monitor (SIM)  with the design accuracy of 5  used to monitor the secular changes of the total solar irradiance on FY-3 satellite  takes the sun-scanning measurement method on-orbit. Compared to the sun-tracking measurement method  this method simplifies the structure and cuts the cost  but the measuring accuracy is affected by the sun-synchronous orbit  sunlight incidence angle and the installing angle of the SIM in the satellite. Through the ground calibration experiment  studies on the affection of different sunlight incidence angles to the measurement accuracy. First  by the satellite tool kit (STK) simulation software  simulates the orbital parameters of the sun-synchronous satellite  and calculates the Sun ascension and declination at any time. By the orbit coordinate transformation matrix gets the components of the Sun vectors to the axes of the satellite  and base on the components designs the field of view and the installing angles of the SIM. Then  designs and completes the calibration experiment to calibrate the affection of the incidence angles. Selecting 11 different angles between the sunlight and the satellite X-axis  measures the total solar irradiance by the SIM at each angle  and compares to the irradiances of the SIAR reference radiometers  and gets the coefficient curves of the three channels of the SIM. Finally  by the quadratic fitting  gets the correction equations on the incidence angles: R 1=5.7110-52 -2.45310 -3+1.0302  R2=2.8410-5-1. 96510-3+1.0314 and R3 =1.7210 -52-4.18410-4+0.9946. The equations will aimprove the on-orbit measurement accuracy of the solar irradiance  and are very important to the on-orbit data processing after the satellite launched. 2011 SPIE.
