摘要：
Galileo Satellite Navigation System has been put into trial operation at the end of 2016. Whether Galileo Satellite Navigation System can be used independently for navigation and positioning needs to be analyzed and evaluated because it is not yet in full constellation, especially the performance of Galileo Precision Point Positioning is worth studying. This paper evaluates the global positioning performance of Galileo Precision Point Positioning. The Galileo satellite visibility, average DOP value, convergence speed and positioning accuracy of PPP in different regions are evaluated by experiments with MGEX observation data. The experimental results show that in the initial operation stage of Galileo, the convergence speed of Galileo PPP is slower due to fewer visible satellites, but the positioning accuracy of static PPP is comparable to that of GPS PPP. At the same time, the positioning accuracy and convergence speed of GPS/Galileo PPP is better than that of Galileo PPP.
