Influence of satellite-to-ground link on the autonomous navigation of navigation constellation

Abstract

Autonomous navigation is a significant element of satellite navigation systems. Current generation autonomous navigation of navigation satellite constellation typically employs the inter-satellites information only, which shows vulnerabilities due to the restriction of deficiencies and the on board processing units of inter-satellites links. In this paper, we describe an autonomous navigation of constellation method in virtue of satellite-ground links, along with aspects of the operating mode of autonomous navigation and the autonomous navigation of constellation with the aid of satellite-ground links. The proposed method is tested by simulations, proving its effectiveness for the precision improvement of autonomous navigation of constellation. © 2012 Springer-Verlag.
