Abstract
Based on GPS precise ephemeris,the precision of broadcast ephemeris is analyzed.The effect of the broadcast ephemeris error on different length baselines is investigated by using some numerical examples.In the relative positioning mode,an appropriate range of applying the broadcast ephemeris is suggested.
