POSITIONING
China University of Geosciences, Beijing 100083
Abstract A new strategy derived from robust estimation to improve the convergence time of precise point positioning is presented, and the 24 1hour data are processed to test the strategy. The results show that robust estimation is effective to improve the convergence time of precise point positioning, it also shows the success rate of robust estimation is better than that of least squares. The positioning results show that robust estimation is significant to improve the positioning accuracy of small spans, and could reduce the affection of the observations which their ambiguities aren’t convergent effectively.
Key words ：
Precise Point Positioning（PPP）
