Abstract We process BDS/GPS data from 5 IGS tracking stations and vehicle experiment by adopting precise satellite orbits and clocks. The paper comparatively analyzes the effectiveness of three velocity determination methods: Doppler measurements, the carrier phase derived Doppler measurements, and the kinematic PPP velocimetry. The results show that in the simulated kinematic experiment, the precision of three methods in horizontal direction could be up to 10 mm/s, 4 mm/s, 5 mm/s, respectively. In the dynamic environment, the precision of the Doppler measurements from carrier phase and the kinematic PPP velocimetry in horizontal direction could be up to 5 cm/s and 8 cm/s, respectively. The accuracy of the two methods is limited by the velocity of the carrier. Velocity determination accuracy of BDS is comparable to GPS.
