Broadcast Ephemeris Accuracy Analysis for GPS Based on Precise Ephemeris
Applied Mechanics and Materials, 2014The accuracy of broadcast ephemeris is an important index of a satellite navigation system. The theory and method of precise ephemeris assessing broadcast ephemeris are introduced. The accuracy of GPS satellite broadcast ephemeris is assessed with the precise ones provided by IGS.
