Summary
In this article performance estimates for the accelerometers, the star sensors and the K-Band ranging system onboard the GRACE satellites are given. It is shown that the accelerometers perform slightly worse than specified and that the star sensor and K-Band ranging system performances agree with the specifications. It is also demonstrated that mainly for the accelerometers performance assessment further investigations are needed as effects of unknown origin affect the measurements. For each instrument the results from the highrate L1a to the filtered and downsampled L1b data processing are shown and discussed. Concerning the accelerometer processing, good agreement with the data provided by JPL has been reached, concerning the star sensors and the K-Band system differences remain.
