基于极球面投影的惯导高纬导航方法
High latitude navigation method for inertial navigation system based on polar stereographic projection
摘要
Abstract
A inertial navigation method based on polar stereographic projection was researched to sovle problems that existing inertial navigation methods can not meet the demand for great circle sailing and navigation errors increase in high latitude regions .Ellipsoid grid heading reference model was con-structed ,drawing from the thought of the polar stereographic projection grid navigation .Then ,by u-sing original calculating information of inertial navigation systems (INS) ,grid heading and grid veloci-ty calculation were achieved .Finally ,high latitude navigation parameters performanced evaluation on the basis of the analysis of high-latitude navigation methods inhibition mechanism .Theoretical analy-sis and simulation results show that this method can effectively improve the navigation performance of INS and meet the demand of carrier sailing in high latitude regions .关键词
