姿态误差算法的比较及研究

Comparison and Research of Attitude Error Algorithm

姿态解算一直以来都是导航系统研究的重点,保证被测量载体的姿态信息的精确解算则是一项重要的任务,由于刚体的不可交换性,导致误差的出现,在圆锥运动下产生的圆锥误差是惯导系统的重要误差源,对此提出一种改进的圆锥误差补偿算法并与捷联惯性导算法比较,并以典型圆锥运动做为输入,对其进行数字仿真分析,通过改变经典圆锥运动部分参数,检验圆锥误差补偿的解算过程精度,得出改进的圆锥误差补偿算法是解决圆锥误差的有效方法。

Attitude algorithm has been a focus in the study of navigation system,to ensure the precision of measuring carrier atti- tude information decoding is an important task.Due to exchange of a rigid body,lead to the emergence of the error.in conic motion of the cone error is one of the important error sources for inertial navigation system.To put forward an improved conic error compensation algorithm and compared with guide strapdown inertia algorithm,in typical cone movement as an input to the digital simulation analysis,by changing the parameters of classic conic motion parts,inspection taper error com- pensation process of calculating accuracy.
