    Abstract
  • IGSO is a special geosynchronous circular orbit with good track stability, long control period, and can cover the high latitudes. On the basis of this, the influence of IGSO satellites on the accuracy of BDS triplefrequency singleepoch baseline resolution is studied. This article uses two short baselines in Inner Mongolia and Anhui, on the basis of the GEO and MEO satellites, an IGSO satellite was added to participate in the solution increase by visibility. The experimental results show that when adding 2-3 IGSO satellites with good visibility, the success rate of ambiguity resolution is the highest, and the positioning accuracy is the best; compared with the addition of 1-3 IGSO satellites, the ambiguity resolution success rate and the positioning accuracy were decreased when 4-5 IGSO satellites were added.
