A New Method for Improvement of Convergence in Precise Point Positioning

  • The current mathematical model and parameter estimation method in precise point positioning(PPP) are introduced,then the adaptive filtering by selection of the parameter weights in the parameter estimation is applied.The selecting weight fitting method is employed to determine the initial parameters and the corresponding variance-covariance components.Two numerical experiments demonstrate that the position precision can achieve decimeter to centimeter in a short time,and that the feasibility and validity of the new method can be ensured.
