摘要
推导了采用6个加速度构建无陀螺惯性导航系统的位置参数解算方程,分析了6加速度计的无陀螺惯性导航系统中加速度计对准误差与位置解算误差的关系,并推导出了位置误差的解析式。针对不同情况,通过仿真试验,发现对准误差对位置计算误差影响显著,且在相同对准误差条件下,位置解算误差随加速度计的安装距离增大而减少的特性。
The page analyzes the relationship between the position error and misalignment error of the six accelerometer based GF INS, and derives analytical equation of the position error, The simulation are made according to different error level and different accelerometer setting scheme, the results verify that the position error resulted from the accelerometer misalignment error is very large, and decrease with the longer accelerometers＇ mounting distance.
