Summary
Analysis of CHAMP GPS data through a reduced dynamic methodology has yielded precise Cartesian positioning for subsequent analyses for gravity field and geodynamic parameters. Results are accordingly presented of (i) a gravity field recovery, (ii) the bias and scale factors for the three axes accelerometer data and (iii) the apparent thrust forces estimated as parameters over a 13-month period. As a consequence we are able to consider the stability of the accelerometer parameters recovered daily or monthly. Analysis of the thruster data will quantify the magnitude of the additional forces involved and the stability, if any, of these forces over an extended period.
