摘要
Abstract
The clock error of the reference station is one error source of the satellite positioning system. In order to correct the error and improve the accuracy of positioning,this paper proposes a new clock error estimation method based on three-parameter clock model,the Singer model of moving-target and Kalman fiher algorithm. The simulation uses GPS data from NOVATEL receiver for reliability, and based on Matlab calculates the clock error parameter, position coordinates and positioning errors. The results demonstrate that the method effectively improves the accuracy of satellite positioning system.关键词
