惯性导航平台的三轴伺服测试

Three-Axis Servo Drift Test of Inertial Navigation Platform

本文分析了三轴惯性导航平台的三轴伺服测漂问题,首先分析平台轴和转台轴之间的座标变换,然后分析转台轴相对地球的不同安装方式下的运动方程。在无漂移时转台的表现运动得到解析解,这对有漂移时的数据处理方法提供了理论基础。此时漂移运动分量和表现运动分量应从总运动过程中分离出来。

In this paper the three-axis servo drift test of inertial navigation platform is analyzed.At first the coordinate model is given.After that the table mo- tion without drift by various orientations are discussed,The analytical solutions are obtained.This is the theoretical foundation for separating the drift from the total motions.
