    Abstract
  • The PPP-RTK technology, which combines the advantages of network RTK (NRTK) and precision point positioning (PPP) technology, has become a hotspot of current precision positioning research. This paper proposes a solution to quickly fix the ambiguity, Which can improves the reliability of ambiguity estimation. In the experiment, the measured data of the IGS station are used to perform PPP-RTK positioning solution, Statistics show that:When using this algorithm to locate the static data, it takes about 20 minutes for the data convergence time to reach the centimeter level. The accuracy of the positioning results has reached the centimeter level, The positioning accuracy in the plane position direction is better than 3 cm, and the positioning accuracy in the elevation direction is better than 5 cm.
