Kurzfassung
Modifications of the Attitude Control System of the ROSAT spacecraft are described. The satellite has successfully performed the first all-sky survey with an imaging high precision X-ray telescope. During the following pointing observations of selected sources, severe degradation of the gyros forced a revised, restricted programme for five months. During this time the onboard software was modified to use the available magnetometer and coarse sun sensor measurements. The attitude control accuracy could thereby be improved again to allow an autonomous star acquisition by the star trackers for high precision pointing. This allowed the resumption of the nominal mission under conditions specified prior to launch.
