| Abstract: | In this paper,BDS/GPS joint positioning mathematical model was introduced.BDS/GPS dual system joint single-point positioning was implemented based on the VS2018 platform program,and the accuracy and the stability of GPS system and BDS/GPS joint positioning were verified under the shade of trees and buildings by analyzing the measured data.Experimental results showed that the multi-system joint positioning could significantly improve the positioning accuracy and the stability under the complex environments. |
