IN-FLIGHT SENSOR PERFORMANCE OF THE ROSAT SPACECRAFT AND CONSEQUENCES FOR THE ATTITUDE RECONSTRUCTION ON GROUND

Kurzfassung

The scientific payload of the ROSAT-Spacecraft consists of a large X-ray telescope carrying two Proportional Counters together with a High Resolution Imager and smaller XUV-telescope called Wide Field Camera. The success of the ROSAT-mission depends significantly on the accuracy of the final attitude solution on ground based on rate integration gyro and star tracker camera measurements. So the performance of these attitude measurement devices influences directly the quality of the attitude solution.
