摘要
在惯性制导中,制导工具误差和基准误差是造成飞行器误差的主要原因,而卫星制导又易受外界环境的干扰,利用星敏感器的测量值,既可以修正工具误差和制导基准误差,又不受外界干扰的影响,因此星光制导在制导技术中得到广泛应用。通过研究初始对准修正方法,分析不同条件对修正效率的影响,提出初始对准方案使用的应用背景。
Guidance instrument error and reference error may cause error aircrafts in SINS. GPS guidance tends to be disturbed. Celestial navigation is widely used for its correction in guidance instru- ment error and reference error through measured value from star sensor and its anti-disturbance feature. The influence of correction efficiency in deferent situations has been analyzed and the application environment of initial alignment correction is proposed.
