Abstract By Euler’s theory, the plate motion error model was established. According to robust estimation, a new method was proposed,which can both detect the abnormal stations automatically and acquire motion parameters quickly at the same time. For global 9 plates，the position and size of the abnormal stations was detected accurately and global plate motion model based on ITRF2008 was constructed successfully.The results show that the robust estimation before removing abnormal stations are as good as the least squares after removing the abnormal stations. Comparing with the models that other scholars researth, it’s consistant as a whole and higher obviously at accuracy.
