Abstract: This paper proposes a new method based on relationship of multiple receiver ambiguity to solve the re-convergence problem in kinematic PPP due to the satellite signals interruption. The method makes full use of multiple receivers located in different locations of the survey vessel. Because of the different locations, the signal interruption may be not simultaneous for different receivers. The method establishes the relationships of ambiguity between different receivers and then obtains the priori ambiguity of the receiver that need re-convergence, and then completes the re-convergence of kinematic PPP. Experiments show that the success rate when fixing double-differenced ambiguity with baseline length constraint is more than 99%; when fixing double-differenced ambiguity, no matter how long the satellite signal is interrupted, the proposed method can complete re-convergence of kinematic PPP in one epoch. Moreover, the positioning accuracy after re-convergence is as same as the before.
