  • Based on the positive bias property of the Time-Of-Arrival(TOA)measurement error caused by Non- Line-Of-Sight(NLOS)propagation in the mobile communication environment, a simple geometrical position location method is presented. Some sites are determined according to the coordinates of the base-stations and TOAs, and the location estimation of mobile station is achieved by averaging the coordinates of these sites. The simulation results show that this method can effectively improve the location accuracy in NLOS environment with little degeneration to mobile location in LOS environment.
