Flight results of the high accurate attitude determination concept for the X-ray satellite Rosat
Abstract
The Rosat mission requires highly accurate attitude data. Therefore an attitude determination procedure has been established using star camera measurements and gyro data. A quaternion representation of the attitude is used. A Fiducial Light Star system monitors the relative motion between telescope axis and star cameras. The reference is a star catalog for the epoch 2000.0. Results of first flight data demonstrate the capability of the Post-Facto Attitude Determination System to obtain attitude accuracies of a few arcsec.
