Abstract : Progress is reported in the planning and construction of the Space Radio Systems Facility, a facility for studying the utility of systems objectives in the millimeter wavelength region. The Space Radio Systems Facility consists of a precise 15-ft antenna with its associated digital control and data processing equipment. A description of the instrumentation is given, and the initial observational plans are outlined. A technical description is given of the planning and fabrication of the precision large aperture antenna. The aperture is circular, and the configuration is Cassegrainian. Surface tolerance measurements indicate a prospective capability of efficient operation at wavelengths down to 1 mm (300 Gc) over the total 15-ft diameter. A description is given of the peripheral components and the associated digital equipment required to accomplish precise automatic control of the antenna attitude and realtime data reduction.
