Control Electronics System for the University of Wisconsin OAO Experiment

This control electronics system provides for remote control programming of variable optics of seven telescopic instruments which form a major payload for the first Orbiting Astronomical Observatory (OAO). Controlled variables include measurement channel gain, viewing angle, collimation, and spectral band. Features of the electronic system include: (1)Selective redundancy of command code bits, use of control modes of operation, and sequence of data readout format. (2) Conversion of the complete system design into qualified hardware consuming less than 8 watts average power.
