Title: Architecture for processing wide field-of view sun sensor signals for satellite applications

Abstract: The present invention is embodied in an apparatus for sensing solar position. The apparatus includes a precision wide-field-of-view (WFOV) passive optical sensor head and a set of interface electronics disposed within a spacecraft computer, which is located remotely from the precision WFOV optical sensor head. The interface electronics convert current signals supplied by the precision WFOV optical sensor head into digital signals usable by a spacecraft control processor. The spacecraft control processor uses the digital signals from the interface electronics to precisely determine the attitude of the spacecraft.
