摘　　要：分析利用载波相位变率实时测速的误差来源及其对测速的影响,并利用静态观测动态处理方法对实时单点测速精度进行验证。结果表明利用载波相位变率和GPS广播轨道实时单点测速,水平分量可达到几个mm/s,垂直方向优于1 cm/s。This paper overall analyzes and summarizes all kinds of errors and their effects on the realtime singlepoint velocity determination using the carrier phase changerate. 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 changerate and realtime singlepoint velocity determination of broadcast GPS orbit.
