The Research On The Technology Of The Star MAP Simulation For Dynamic Star Simulator Based On LCOS

For the need of dynamic star pattern simulation, the paper launches a software design on star pattern simulation. On the basis of the star simulator's components and main technique data, the paper accomplishes the design on software and hardware of star pattern simulation.This paper chooses the Liquid Crystal on Silicon (LCOS) as the display device of the star simulator and designs the interface circuit in order to make the singal passed from computer to LCOS. By using Visual C++, the paper studies the searching of the star catalog, converting the coordination, simulating the star magnitude. According to the real-time attitude of satellite to calculate the axis point to the current attitude and search information of the star in the field of 10°x 10°to show the star map on star pattern simulation computer. According to the display format on LCOS, the system can transform the star pattern simulation into the corresponding format and show it on LCOS.
