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

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.
