Simulation of Trajectory Parameters of Motion of an Object near the Pole Using Quasi-Geodetic Coordinates

Abstract

The paper discusses the challenges of inertial navigation in polar regions, where it is impossible to determine the longitude and true heading at the poles. To overcome this difficulty, it is proposed to use quasi-coordinates and quasi-attitude angles, as well as relevant quasi-ECEF and quasi-geodetic coordinate systems. It is proved that the quasi-geodetic (quasi-geocentric) coordinates, quasi-attitude angles, velocity of an object and inertial sensors readings can be simulated by using quasi-coordinates instead of traditional ones.
