Workshop on Satellite Power Systems (SPS) effects on optical and radio astronomy

Description: The impacts of the SPS on astronomy were concluded to be: increased sky brightness, reducing the effective aperture of terrestrial telescopes; microwave leakage radiation causing erroneous radioastronomical signals; direct overload of radioastronomical receivers at centimeter wavelengths; and unintentional radio emissions associated with massive amounts of microwave power or with the presence of large, warm structures in orbit causing the satellites to appear as individual stationary radio sources; finally, the fixed location of the geostationary satellite orbits would result in fixed regions of the sky being unusable for observations.

Remote wind measurements with a new microprocessor-based accumulator device

Description: The employment of a unique microprocessor-based accumulator device for remote meteorological measurements is described. The unit was designed for remote application with wind instruments to respond to the need for a very inexpensive survey unit to provide statistical summaries of basic wind data for the wind turbine siting decision process. While it is versatile enough to be used in many other remote measurement scenarios, the device will be described primarily in its application to wind measurements for siting wind energy conversion systems (WECS), otherwise known as wind turbines.

Wind prospector's instrument

Description: In the initial evaluation of a prospective wind turbine site, wind measurements must be made at that site. The report describes an inexpensive data collection device consisting of a microprocessor unit that can be used to record such measurements, producing statistical summaries of wind behavior at the site. Prospectors have often used analogous devices to locate deposits of mineral resources; thus, this device is called a wind prospector's instrument.
