Carrier phase ranging is usually used for high-precision positioning. When the signal of the Global Navigation Satellite System (GNSS) receiver is affected by occlusion, interference and other environments, the carrier phase is prone to the problem of discontinuous tracking, which affects the positioning accuracy. To solve this problem, this paper proposes a carrier phase prediction method using the vector structure. The predicted value assists carrier phase tracking. To achieve better tracking of the carrier phase with the predicted value, the influence proportion of the predicted value on the carrier phase is determined by the quality of the received signal. Finally, the experiment verifies that prediction of the carrier phase through the vector structure can effectively improve the tracking ability of the carrier phase, so as to keep a continuous tracking of the carrier phase and effectively improve the positioning accuracy.
