Abstract Based on the measured data of MGEX stations, we use the cross validation method between systems to check the quality of Beidou/GNSS precise point positioning (PPP). We analyze the accuracy and convergence speed performance of multi-GNSS PPP with different combinations. The results show that compared with single BDS, multi-GNSS can accelerate the convergence speed as well as the accuracy of PPP. The greater the system combinations number, the higher the positioning accuracy and the faster the convergence speed of PPP. Then, we use the cross validation method between systems to check the accuracy and reliability of PPP results in static, pseudo-dynamic and marine dynamic positioning modes.
