| Abstract: | The cycle slip detection and its reparation perfectness can directly influence the aeeuraney of GPS positioning. In order to effectively detect whether the cycle slip is less than 1 cycle, a new algorithm using the dual frequency observations to detect the cycle slip in carrier phase measurements was proposed. The mathematical model of the algorithm is simple and convenient for computation, which can detect the cycle slip less than 1 cycle. At last, static and dynamic experiments were performed and results show that the algorithm is feasible and effective. |
