Abstract According to the relationship between the phase biases and precise point positioning(PPP) model in ambiguity resolution, the estimation model for phase biases is derived based on the directional statisticsnd, and the ambiguity fixing scheme for PPP is designed which can solve the problem of ambiguity fixing for PPP. The results show that, based on phase biases correction, the convergence speed of PPP ambiguity fixed solution is improved by 3/4 compared with floating solution, the Ratio value is improved by three times, and positioning accuracy is also obviously improved.
Key words :
Precise Point Positioning(PPP)
phase biases
ambiguity
fixed solution
