When single satellite navigation system is used for positioning, there exist the following problems: accuracy of positioning is low and reliability of positioning is also low. This paper investigates the combined positioning algorithm of BDS and GPS for static and dynamic observation point. For static observation point positioning, the weight coefficient integrated positioning algorithm of BDS and GPS is proposed. For dynamic observation point positioning, the Kalman filter can achieve smoothing of the movement trajectory which is the once combined observation point. The experimental results show that the combination of BDS and GPS is more accurate and reliable than any single system for static observation point positioning. At the same time, for the consideration of the weight coefficient, the system has good adjustability and practicality, and the Kalman filter can better modify the dynamic combined observation point.
