一种校准机(舰)载惯导航向偏差的方法

A New Method for Collimating the Navigation Deviation in Airborne(Seaborne) Inertia Navigation System

机 (舰 )载设备在测量过程中 ,需要提供准确的飞机 (舰船 )俯仰、横滚、偏航等姿态信息 ,但由于机 (舰 )载惯导系统提供的偏航数据精度较低 ,不能满足测量的需要 ,需要对惯导进行校准。针对这种情况 ,探讨了一种利用机 (舰 )载光测设备测量方位标修正惯导航向偏差的方法。由于光测设备测量精度比较高 ,本校准惯导方法满足靶场试验的需求 ,达到了修正系统误差的目的。试验证明 ,这种方法是有效。

When measuring,the airborne (seaborne) instruments must be able to offer accurate information on elevation,lateral rolling and navigation deviation.Because of the relatively low accuracy of navigation deviation information from airborne (seaborne) inertia navigation system,this information need to be collimated.This paper discusses a new method that utilizes optical measuring instruments to measure the azimuth points and collimates the navigation deviation.Because of relatively high accuracy of optical measuring instruments,the method discussed in the paper can meet the requirement of experiments in sheet field and reach the aim of collimating systematic deviation.Experiments show that the method is effective and viable in applications.
