    Abstract
  • GEO satellites are the main components of the BDS constellation.In order to analyze its impact on the positioning performance of BDS-3,this paper analyzed the impact of GEO satellites on the positioning accuracy of BDS-3 pseudorange single point based on the measured data of MGEX tracking station.The research found that the GEO satellite can effectively improve the BDS-3 satellite visible number and satellite space geometry,and can effectively improve the BDS-3 pseudorange single-point positioning accuracy.The BDS-2／BDS-3 GEO satellites make the BDS-3 pseudorange single-point positioning accuracy better than that of any single-system GEO satellite.The horizontal positioning accuracy of BDS-3 GEO satellites pseudorange single-point positioning is improved within 30％,and the positioning accuracy for elevation direction is improved within 20％.
