AbstractPrecise CHAMP orbits have been computed in the framework of the IGS/LEO CHAMP Orbit Comparison Campaign for a period of 11 days in May 2001. A reduced-dynamic orbit determination strategy has been applied based on ionospheric-free triple-differenced GPS phase measurements along with precise GPS orbits computed by the International GPS Service (IGS). The resulting CHAMP orbit accuracy is assessed using GPS observation residuals, orbit overlap statistics, independent satellite laser ranging (SLR) residuals and comparisons with orbits computed by other institutes. These evaluations indicate a 3D orbit accuracy of the DEOS orbit solution at the sub-decimeter level.
