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.

In this paper  a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process  the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance  the uniformity of the screen color will be deteriorated. Firstly  the color tolerance of vision was calculated by the color-difference formula. Secondly  in the full-color LED display experiments  it was analyzed that the tri -color tolerance values are respectively 2.5  2.8 and 1.3. According to the tri -color tolerance values and the color difference formula  the express of the quantization precision  gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data  it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11  14]  and when the range was [1  11]  the value of the color difference was also reduced significantly. 2009 IEEE.
