三种传递对准方法的对比研究

Comparsion on Three Methods of Transfer Alignment

摘要:

传递对准是动基座对准的一种方法,其有多种匹配方案。文章对比了“速度”匹配和“姿态”匹配、“速度+姿态角”匹配3种传递对准方案。运用卡尔曼滤波算法,对失准角进行估计,并对估计结果进行比较,分析了3种匹配方案的对准精度及适用性。

Abstract:

Transfer alignment is one kind method of moving base alignment, and it has many kinds of match schemes. In this paper, the “velocity” match scheme, the “attitude” match Scheme and “velocity+attitude” match scheme were contrasted. Kalman filtering algorithm was used to estimate misalignment angle. The simulation results were compared to analyze their alignment accuracy and adaptability.
