Abstract:In order to solve various types of coordinates amendment problems of monitor stations in satellite navigation system, it is necessary to accurately give the change rate of the position for each ground station caused by the plate movement. The measured velocity fields computed from GPS observation data of China Crustal Movement Observation Network was adopted, and established virtual local plate motion model by using sliding Euler vector modeling, accuracy analysis shows that the result in the eastwest direction has the accuracy of 2.092 mm / a, in the northsouth direction has the accuracy of 2.072 mm / a, in sparsely distributing areas and border of China, the accuracies are not significantly reduced. So the model can be used to amend the coordinates of various types of ground stations in China’s satellite navigation system.
