摘要：

The problems met in high dynamic circumstance during measuring GPS carrier phase and detecting data transition are analyzed. The signal parameters are estimated through extended Kalman Alter (EKF) algorithm. And a simple data transition and parameter correction method is studied emphatically. The tracking performance and tracking error of this simple method are simulated and compared with no data transition detection method. The simulation shows that this data transition method conduces to improve the phase estimation precision, and the dynamic performance of the algorithm is ameliorative too.
