Abstract
A processing system was designed and implemented to support beacon acquisition, precision beam pointing, and command/control functions for the Optical Communications Demonstrator. The central processor operates as a command controlled embedded system, but by blending real-time and linear design techniques, a single digital signal processor handles all spaceborne functions. Real-time functions include operation of a CCD array detector, calculation of centroids, computation of point-ahead error, and execution of a steering mirror servo loop at 2 kHz update rate. Linear functions include command interpretation, diagnostic control of all functions, storage and interpolation of data for acquisition and point-ahead calculation, downlinking of status information, hardware control, transmit laser control, and image capture.
