For enhanced accuracy requirements and for autonomous spacecraft operations a family of attitude sensors was developed, consisting of a Sun sensor assembly and a star tracker system. Both types of sensors are based on a common electronic design, and provide for internal data evaluation and real time or offline self test features. The interface to the AOCS (Attitude and Orbit Control System) is established via serial bus electronics and the sensors are easily adaptable to different mission types.
