Due to the lack of visible satellites in some areas, GPS may become more inaccurate, and sometimes even lead to malfunction. Generally, the base stations can participate to increase the positioning accuracy. In some areas, the number of visible satellites is less than four but multiple base stations existed in the area, this thesis propose a method called Hybrid Positioning Improved Method (HPIM) to take this situation into consider to improve the positioning performance. The proposed HPIM adopted the TOA (Time of Arrival) method for distance calculation. The simulation results show that our proposed HPIM method outperformed the GPSone method on the comparison of error range and positioning success rate.
