Scientific paper
The principle of operation of the Giotto Camera is presented. The onboard computer of the camera system is introduced and the principle of the tracking procedure is explained. The test environment for the S/W-development of the onboard computer is outlined. The data generated by the tracking system during the Halley flyby are analyzed. It became evident that the tracking system operated flawlessly. The observed anomalies could be traced to the pointing mechanisms. The operational capability of the camera tracking system is not questionable and hence does not object the planned reactivation.
