摘要
分析了动态条件下,载体姿态参数的惯性测量问题。以实际工程应用为背景,推导了运动约束条件下,基于两个激光陀螺、两个加速度计的系统姿态测量模型。根据载体姿态动态变化的不同频谱特性,进行了基于频域分析的算法设计,通过实验验证了算法的可行性。
The problem of dynamic inertial angular survey is analyzed in this paper. Based on the practical engineering background, the mathematic model of the system composed of two laser gyros and two accelerometers is derived under the dynamic restriction. The algorithm is designed by means of frequency analysis considering the different frequency spectrum characteristic of the body attitude dynamic changes. The feasibility of the method is proved by experiments.
