英文摘要	Using the broadcast ephemeris and precise ephemeris provided by the international GPS service for geodynamics (IGS), the precision of the orbit computed by GPS broadcast ephemeris are analyzed. The orbit precision of broadcast ephemeris is about 5 meters. This paper describes the approach of point positioning using pseudo-range in detail, and then discusses some problems in data processing. Based on this, the differences of positioning accuracy between broadcast ephemeris and IGS precise ephemeris are analyzed and compared. The experiment data is set from IGS tracking stations. With the result calculated, some conclusions are given in the end. In addition, some beneficial conclusions on improving positioning precision are gained. ? 2012 Springer-Verlag Berlin Heidelberg.; EI; 0
