In order to find a new method of evaluating the true heading accuracy in flight test,by using the global positioning system(GPS) as a reference,two different types of inertial navigation system as experiment objects,the correlation between the track error and the true heading error of inertial navigation system(INS) has been researched through the flight test.Test data and analysis results show that the use of track error to assess the true heading accuracy indirectly is credible.
