遥测测试中的IMU初始对准问题

Algorithms for Initial Alignment of IMU in Telemetering

本文在分析惯性测量单元(IMU)的解算算法的基础上,利用姿态转动分析了遥测测试中惯性测量单元(IMU)数据解算的初始四元数提取方法,并对其进行推导和验证,仿真结果表明了该方法的有效性。

Based on the analysis of algorithm of Inertial Measurement Unit （IMU）, the algorithm of quaternion extraction from initial transformation matrix of IMU is provided with attitude - gyration.The advantage of the suggested methods is tested by the numerical simulating and the result is feasible and reasonable.
