摘要
推导了捷联式制导系统中四元数微分方程的数值求解方法,分析了误差的传递。为了使计算得到的四元数为单位四元数,构造了保持范数算法和误差自适应校正算法。
The numerical method solving quaternions differential equations in the strapdown guidance sys- tem is derived,and error transfer is analyzed.The holding norm and the adaptive error correction algorithms have been constructed for geting unit quaternions.
