The GDOP value analysis in COMPASS satellite navigation

Zhongwen Gao, Hongyu Zhang

Abstract

Compass satellite navigation and positioning system is a new generation of independently developed satellite navigation system in China. In this paper, it establishes pseudorange error model by Compass navigation and positioning system. Then it deduces and analyses the geometric error factor of the system. And the navigation and positioning accuracy of the system is analysed. The improved algorithms is proposed. Accordingly, coputational efficiency of accuracy factor and the calculation of the stability is improved.
