A Simple Double-Star Positioning System Positioning Algorithm

Abstract:

Double-star navigation and positioning system use Double-star positioning system which basic principles are the intersection of three balls. Two measurements relate to the distance of the two satellites and the user, and the third measurements which relate to the user elevation are the critical factor to determine the positioning precision. For this reason, based on the Earth ellipsoid geometry and geodetic latitude knowledge, this paper derives the accurate model of the third measurement, and establishes a user location algorithm. The algorithm is simple and easy to understand, and simulation tests show that the algorithm has fast convergence and accurate positioning.
