Abstract

The difference between the attitude angle and the rotation angle will cause the modeling error of DTG. The accurate calculation model of azimuth is established according to the relationship between the attitude angle and rotation angle. The error between the accurate calculation model and the traditional model is analyzed by simulating. The simulation show that the modeling error is proportional to the tilt angle and the pitch angle, when the change of the tilt angle and the pitch angle is 1°, the max change of the modeling error will be 3.6701.
