In GNSS multi-system fusion positioning, inter-system bias must first be considered. The analysis of the inter-system bias characteristics is helpful for the prediction and modeling of the inter-system basic, improving the precision and convergence speed of precise point positioning. This paper constructes GPS/BDS ionospheric-free combined PPP observation equation by considering ISB parameters. On this basis, the difference between BDS-2/GPS ISB and BDS-3/GPS ISB, the characteristics of BDS-2/BDS-3 ISB and its impact on PPP are analyzed. The results show that GPS/BDS ISB estimation by fusion of BDS-2 and BDS-3 observation data possesses the average characteristics, the estimation process is more stable, the positioning result accuracy is higher, and the convergence speed is faster. In the static state, the positioning accuracy is about 0.6 cm in N direction, about 0.9 cm in E direction, and about 1.4 cm in U direction. The convergence time is about 15 min. The BDS-2/BDS-3 ISB is within ± 10 ns, and the long- and short-term changes are stable, depending on the receiver type. Considering the ISB between BDS-2/BDS-3 systems can help improve positioning accuracy and convergence speed.
