Precision Orbit Determination of CHAMP Satellite with cm-level Accuracy

    Abstract
  • The precision orbit determination of CHAMP satellite was done through PANDA(position and navigation data analyze) software,using the onboard GPS data from day 126 to 131 of year 2002.The orbit accuracy is assessed by analyzing the difference from GFZ precision orbits,the data residuals and the satellite laser ranging(SLR) residuals.The comparison results show that the accuracy of the orbits obtained is 4-5 cm in radial and 6-8 cm along and across the track.
