NAVCAST – Galileo Clock and Ephemeris corrections
Clock & Position: GSAT 0202
Satellite orbit correction shows the difference between the satellite position as obtained from precise orbits and the satellite position as derived from the broadcast orbits. The difference between both satellite position estimates shows a sudden jump every two hours due to an update of the broadcast orbits.
Satellite clock correction shows the difference between the satellite clock estimation as obtained from RETICLE and the satellite clock offset derived from the broadcast ephemeris.
