Abstract :
GpsOne, which fuses GPS and wireless base station positioning signals, is a hybrid wireless assisted GPS technology proposed by Qualcomm Inc. It provides positioning service through wireless communication networks. Compared with GPS, gpsOne is more suitable for vehicle navigation due to its wider workable regions (urban, rural and even underground areas), higher positioning accuracy, lower price and no cold start. However, single gpsOne cannot be used for vehicle navigation due to its large positioning error (more than 100m) when GPS signals cannot be received completely. Therefore, gpsOne should be assisted with other positioning modes to promote the reliability, redundancy and fault-tolerance of vehicle navigation system.
