Abstract

In some restricted area, position precision of GPS is not satisfied because the amount of visible satellites is limited. To this dilemma, a novel GPS algorithm based on constant velocity assumption proposed to improve location precision. The target assumed to move with constant velocity, so corresponding GPS positioning model derived. In order to enhance algorithm performance, a biased estimator introduced in the model computation. Theoretic analysis and simulation results verify that this estimator can greatly improve estimation precision, so it has practical values.

Key words： GPS positioning; biased estimation; Cramer-Rao bound; location precision
