Open full text 9 citations

Abstract

The precision orbit determination of challenging minisatellite payload (CHAMP) satellite was done based on position and navigation data analyst (PANDA) software which is developed in Wuhan University, using the onboard GPS data of year 2002 from day 126 to 131. The orbit accuracy was assessed by analyzing the difference from GFZ post-processed science orbits (PSO), the GPS carrier and pseudo-range data residuals and the satellite laser ranging (SLR) residuals.
