Fast Generation of Precision Orbit Ephemeris

R. Marson, S. Lagrasta, F. Malvolti

Abstract:	Aiming at the simulation of the mission ground segment of the forthcoming Galileo constellation, Telespazio tackled the problem of generating the Navigation Message and particularly the calculation of Precision Ephemeris (PE). The approach was recently extended to real GPS constellation vehicles, using as input the accurate orbit position samples which are delivered by the International GNSS Service (IGS). The proposed article describes the developed technique and presents PE determination results obtained with real GPS orbit profiles.
