The Ultra-Wideband Positioning System service of wireless communication industry has become a popular issue in the recent years. This service can provide an accurate location for many useful functions. The main problem that causes the two major errors are: measurement error, and NLOS (Non-line-of-sight) error. Especially the NLOS errors have the most serious effect on mobile position system. This paper will put a high emphasis on how to mitigate the error caused by NLOS. The simulation results show that the proposed algorithm can reach a high accuracy even in a severe environment.
