This paper proposes the acquisition of PNT data based on Beidou navigation satellite system and the joint BDS/GPS joint pseudorange difference algorithm. This paper relies on the DGNSS infrastructure of the Dajishan lighthouse management station of the Donghai Navigation Safety Administration (DNSA) of the ministry of transport of china. BDS and DGNSS were measured and evaluated using static measurement and evaluation methods. The results show that in the scene with strong interference, the static positioning level error of BDS exceeds 20 meters, DGNSS, static positioning level error is less than 2 meters. Therefore, the DGNSS algorithm is used to acquire the PNT data method, which has the characteristics of availability, accuracy, reliability, continuity and robustness, and can be used in the marine intelligent transportation system.
