Abstract This paper presents a Beidou only and Beidou/GPS combined pseudorange differential positioning algorithm for the great application demands of Beidou navigation satellite system (BDS) precise navigation at sea. Land fixed-point test and maritime dynamic test for China’s coastal differential stations’ signal are conducted and the test results are analyzed in this paper. Test results show that: 1) when the distance between user and station is less than 300 km, horizontal positioning accuracy of Beidou is better than 1.5 m (95% confidence level), and vertical positioning accuracy is better than 2.5 m (95% confidence level)| 2) positioning accuracy and data efficient rate of GPS+Beidou combined positioning is better than only GPS/Beidou systems| 3) only Beidou positioning accuracy and positioning performance are satisfied with RBN differential system design requirements.
