Abstract

Rate azimuth inertial platform/Log/Gravity matching is a simple passive navigation system, the high resolution digital gravity anomaly map is essential for this system. The five kinds of gravity anomaly interpolation are introduced, which include bilinear interpolation, Shepard method, gravitational abnormal approximation based on the distance and direction, the improving Shepard method with the characteristics of band, and the improving Shepard method based on adjacent type value point. The corresponding gravity maps of these methods are given, the simulations of different gravity interpolation for RAPINS/Log/gravity matching integrated navigation system are carried out, and the results shows that the different gravity anomaly fitting methods have some influence on the navigation precision, but can limit position error to several grids.
