基于横向地理坐标系的极区惯性导航方法研究
Inertial navigation algorithm in polar regions based on transverse geographic coordinate system
摘要
Abstract
T he problem of inertial navigation in polar regions is that rapid convergence of the Earth′s meridians makes it difficult to establish true heading at high latitudes .To solve this problem ,an iner‐tial navigation algorithm based on transverse geographic coordinate system was presented .A point in traditional equator was selected as the new pole .According to this new pole transverse earth coordi‐nate ,transverse geographic coordinate ,transverse latitude and transverse longitude were defined . Then the mechanical equations were given in order to solve the problem of traditional inertial naviga‐tion in polar regions .关键词
