Abstract
In 2004, the total zero Doppler steering was proposed to minimize the Doppler centroid for SAR applications. It was firstly implemented in the German TerraSAR-X satellite. This satellite was launched May 2007. With the already analysed data, it is now possible to compare the predictions with the already taken data from the commissioning phase. It is shown that after an additional offset in the attitude control system of the satellite, the remaining Doppler centroid is well below 100 Hz as predicted.
