| 摘 要： | 在捷联惯性导航系统中,姿态矩阵可用四元数来表示,从而常常需要计算四元数矩阵微分方程的问题.4阶龙格-库塔法和3阶泰勒展开递推式法对捷联惯导系统的四元数姿态矩阵作仿真,结果表明：在短步长条件,3阶泰勒展开递推式法比4阶龙格-库塔法更有效.本文为改进捷联惯导系统算法提供了参考依据.

| Abstract: | Attitude matrix is represented by quaternion and the problem solving the quaternion matrix differential equation is frequently used in SINS. In this paper the three-order recursive Taylor expanded form and the four-order Range-Kuttle method as the updating algorithm of quaternion is simulated. The result proved that under the short step length condition three-order recursive Taylor expanded form is more effective than four-order Range-Kuttle method. The paper offers reference for developing SINS algorithm. |
