基于星敏感器的卫星瞬时姿态计算方法
Method calculating of satellitic instantaneous attitude based on star tracker
【摘要】 在分析星敏感器姿态测量原理的基础上,给出了利用方程组进行姿态计算和平差的方法并予以实现,且对仿真结果进行了分析。结果表明,该方法具有较快的计算速度(0.1ms以下),参与计算的星为5~8颗时满足星敏感器的精度要求,基于星敏感器的卫星瞬时姿态计算方法可以在实际中应用。
【Abstract】 The fundamental theory of satellitic instantaneous attitude calculation based on star tracker is introduced, a method using determinantal equations is used to calculate attitude and adjustment, and the simulation result is given and analyzed. The result shows that this method is faster in calculating attitude (under 01 ms) and meets the precision demand for star tracker when there are 5~8 stars. This calculating method can be used in real applications.
