摘要
由于各类误差的制约,单纯依靠卫星导航系统无法满足用户的定位精度需求。星站差分定位系统作为卫星导航系统的重要组成部分,不仅可以有效提升卫星导航系统的定位精度,且覆盖范围广,同时可以弥补可用性、连续性和完好性的不足。论文梳理了典型的国外星站差分定位系统及北斗星站差分定位系统的发展情况,分析了北斗星站差分定位系统发展的必要性。
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.
