A detailed study was carried out on a high accuracy star sensor concept incorporating a CCD area imager as the image analyzing detector. This did not result in a final sensor definition, since several presently unquantified characteristics of CCD have important implications for many aspects of the sensor design. Nevertheless, it was possible to produce outline designs for the telescope and the mechanical and data processing systems, to varying degrees of completeness. It is concluded that the random noise and bias error performance of such a sensor should be within the specification, and that the requirements on manufacture, calibration, and physical and environmental constraints can largely be met. A program to investigate the CCD characteristics in question is proposed.
