【摘要】 针对动态星模拟器中星图模拟与显示的需求,论文开展了动态星图模拟与仿真技术研究。在了解动态星模拟器组成与工作原理的基础上和在满足动态星模拟器的主要技术指标的情况下,对动态星模拟器的星图模拟软件系统与硬件接口电路进行了研究与设计。论文选择LCOS器件作为动态星图模拟器的星图显示器件,并通过对其相应接口电路的设计,实现了星模拟器主计算机与星图显示器件的信号传递。应用Visual C++软件对星表“检索”、坐标转换、星等模拟等关键问题进行研究,软件系统可根据当前航天器姿态信息获得视轴指向,并在动态星模拟器10°×10°视场范围内“检索”星点信息,获得实时的模拟星图,并根据LCOS器件的显示格式,将获得模拟星图转换为相应的格式显示在LCOS器件上。更多还原

【Abstract】 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.更多还原
