Abstract The influence of GEO satellites in BDS high precision relative positioning is studied and analyzed. First, the BDS un-differential observation model is realized, the high precision relative positioning solution model of BDS is derived on this basis. Then, the whole constellation satellites and IGSO+MEO satellites combination are used to carry out in high precision relative positioning processing. Finally, the influence of GEO satellites on BDS relative positioning convergence time, positioning accuracy and PDOP values are further analyzed. The results show that the BDS GEO satellites are beneficial to increase the number of observation satellites, and significantly improve the geometry of the observation satellites and the positioning convergence speed and accuracy. Both the static and dynamic results of the whole constellation satellites of high precision relative positioning are at or better than centimeter level.
