| Abstract: | The effect of pseudo-range by satellite coordinates and satellite clock offset of(?) ephemeris is studied in this paper,which is compare with precise ephemeris and precise clock offset. The software of point positioning is compiled.The rules of point position based on the broadcast ephemeris are calculated and analyzed and some useful conclusions obtained. |
