Abstract This paper overall analyzes and summarizes all kinds of errors and their effects on the realtime singlepoint velocity determination using the carrier phase changerate. Then we verified verifies the accuracy of velocity by a static station’s observations processed in kinematic mode, and the result shows that the horizontal component of the velocity can reach several millimeters per second and the vertical one is better than 1 cm/s by using the carrier phase changerate and realtime singlepoint velocity determination of broadcast GPS orbit.
Key words ：
high-rate GPS
carrier phase change-rate
