摘要
提高惯性平台使用精度的途径之一是用计算机实时补偿平台误差的系统分量。首先介绍仪表和平台的误差模型，重点讨论如何从３个含有测量误差、安装误差和基准漂移误差的加速度计输出信号中，分离出载体飞行加速度沿制导坐标系三轴的分量。对由于惯性基准的漂移而引起的载体姿态角的测量误差也进行了分析。
One of the approaches in the enhancement of accuracy of inertial platform is to perform the realtime compensation of the systematic component of platform's error by use of computer . Beginning with the error models of both the inertial instruments and the platform, this paper has its emphasis laid on how to separate the vehicle's acceleration components, along three axes in a guidance frame, from the three accelerometer's output signals in which the measurement error, installation error, and drift error of platform reference are involved. The measurement error of vehicle's attitude caused by the drift of platform reference is also analyzed.
