Abstract : The Research Note presents a completely general method for evaluating the performance of a mapping camera which is locked to one or more stellar cameras. Image errors in the mapping camera are expressed as functions of a variety of system errors which include star camera format size and shape, star camera focal length, star image identification and measuring errors, number of measured images, the altitude of the star camera with respect to the mapping camera, and, finally, the attitude of the mapping camera with respect to the local vertical.
