Abstract： Withconstructing and completingof global satellite positioning systems such as GPS, GLONASS, Galileo and BDS, using two or more than two signals ofdifferent positioning systems toachieve the combined positioning has become a hotspot in research of navigation.Compared with traditional single system positioning, multi-system combination has stronger environmental adaptability and better performance of determining position, velocity and time.By combined static single point positioning of CAPS, BDS and GPS, we achieve the combined positioning of transponding system with straight forward system, verify the feasibility of CAPS participating in GNSS multi-system positioning, and analyze the positioning performance and accuracy.The analysis shows that CAPS are fully feasible in multi-system positioning, single point positioning accuracy is better than 3 meters and there is room for improvement.The addition of CAPS enriches the selection of GNSS system, and has research significance and application value for improving the diversity of GNSS positioning and the positioning performance.
