Abstract
Using the proposed procedure, the calibration parameters for all three accelerometer data components were obtained. To remove the serial correlation in the POD positions, we used the GLS method together with a fitted autoregressive process. In this way, a realistic estimate of accuracy of the calibrated accelerometer data was obtained for the along-track component. The time evolution of the calibration parameters over a 1.5-year period (08/2002-03/2004) display approximately constant scale factors and slowly changing biases for both GRACE A and B satellites, which is in accordance with the results in the references.
