Abstract：Due to the restrict of various types error,it can not satisfy the positioning accuracy requirement of the users only by means of GNSS. Satellite based differential positioning system as an important component of GNSS,not noly can effectively increase positioning accuracy of GNSS,but also can cover a wide area,simultaneously it can cover the shortage of availability,continuity and integrity.The development situation of representative foreign satellite based differential positioning systems and beidou satellite based differential positioning system is summarized,the necessity of developing beidou satellite based differential positioning system is analyzed in this paper.
