Abstract

In the TDOA location system,the constellation drift can affect the location precision. Aiming at this problem, based on the analysis of the three satellites constellation drifting in a period of time, we proposed the location precision results of constellation drift influence in TDOA location system. Considering the constraint of location accuracy and satellite resources, a feasible recommendation for location maintenance of three satellites system is put forward, which provides the theoretical support for the location maintenance strategy of three satellites TDOA location.
