The project of a PLANETENTELESKOP (telescope for planetary observations), a German space project, is introduced briefly. The pointing measurement system of this proposed spacecraft is very ambitious. Requirements derived from the system ask for available CCD and CID detector arrays to be operated in unusual modes. Changes to readout structures are proposed to facilitate such operational modes. The resulting devices could provide problem solutions to a variety of image tracking applications.
