Beschreibung
Zusammenfassung:	The invention discloses a pseudo distance and Doppler combination differential positioning system and a pseudo distance and Doppler combination differential positioning method. The system comprises a user station receiver and a reference station receiver, and further comprises a GBAS server and a mobile network, wherein the GBAS server is connected with the user station receiver and the reference station receiver through the mobile network. The system of the invention can effectively improve the positioning accuracy of users in a complex urban environment and improve the differential positioning ability of a cheap single-frequency navigation chip. The method of the invention is applicable to high-precision satellite positioning, and improves the precision of the location, speed, clock error and clock drift of a user station.
