Abstract

The Earth-centered, Earth-fixed (ECEF) frame does not have any specific points in the near-Earth space; therefore, it can be used as the basic one for navigation in the polar regions. The paper considers a new algorithm for calculation of ECEF coordinates. The proposed algorithm is complementary to the basic strapdown INS algorithm, which functions in its normal mode from aircraft takeoff to landing. In the polar regions, the aircraft control law that supports flights on the point-to-point principle is based on calculation of ECEF coordinates.

扩展基本捷联惯导系统算法以解决极地导航问题

摘要

以地球为中心的固定地球（ECEF）框架在近地空间中没有任何特定点；因此，它可以用作极地地区导航的基础之一。本文考虑了一种新的ECEF坐标计算算法。所提出的算法是对基本捷联惯导系统算法的补充，后者在从飞机起飞到着陆的正常模式下均起作用。在极地地区，支持点对点原理飞行的飞机控制法则基于ECEF坐标的计算。
