For evaluation, using world-wide 40 IGS (International GPS Service) station observation data, 29 GPS satellite orbits and clocks were determined. A priori satellite position and clock bias were obtained from broadcast ephemerides. Station positions were fixed to the previous week PPP (Precise Point Positioning) results.
