Abstract :
This paper makes improvements aiming at the existing problems of hybrid location algorithm combining BS and satellites data and propose the TDOA/DGPS hybrid location algorithm based on the initial estimation. According to simulations with MATLAB, this new algorithm is proved to improve positioning accuracy further and reduce the amount of computation. But this algorithm can not eliminate effect of NLOS error completely.
