ABSTRACT:
A combined sun and star sensing system for attitude and position control of a space vehicle, includes a star image sensor having a first objective and a first detector array arranged in the focal plane, the objective being constructed for a well defined aberration so as to convert a point like object into a defined spot or area having a diameter larger than the diameter of an element of the detector array; the sun sensor has a regular objective and a second detector array is arranged in the image plane of that objective sun sensor; the two detector arrays have similar and a similar number of detector elements, and are alternately connected to a single evaluating electronic.
