【 摘 要 】

Aiming at the difficulty of ambiguity resolution in GPS dynamic positioning, the radar calibration route is transformed into coordinate function, to compress the search space of Ambiguity Function Method (AFM). The simulation results show that this algorithm not only has the advantage of insensitivity to cycle slip, but also overcomes the shortcomings of large searching space and long searching time of AFM. It is an ambiguity searching algorithm suitable for high dynamics and high precision GPS positioning.
