| Abstract: | The effect of broadcast ephemeris errors on precision of GPS point positioning is analyzed,and the effective level of broadcast ephemeris errors on GPS point positioning is verified by means of differential technical processing on airborne GPS data by using precise ephemeris.The effective level and law of broadcast ephemeris errors on single-reference station DGPS surveying data is introduced.At the same time,the effective level and law of broadcast ephemeris errors by means of differential technical proces... |
