Summary report on SHARP (Stationary High Altitude Relay Platform). Part A, Technical feasibility of microwave-powered airplanes / by G.W. Jull.: Co24-3/7-1393-1985E-PDF
"The SHARP (Stationary High Altitude Relay Platform) system concept envisages use of high altitude microwave-powered airplanes as platforms to relay telecommunications signals. The concept takes advantage of microwave power transmission developments associated with the Solar Power Satellite and High Altitude Powered Platform concepts and adapts these to Canadian needs. Microwave power would be transmitted from a large ground antenna system to an unmanned airplane circling at about 21 km. This power would be converted to dc power using rectennas on lower surfaces of the airplane. The dc power would drive lightweight electric motors. Over the period 1981 to 1984, the Radar and Communications Technology Branch of DOC carried out a series of background research activities on technologies associated with SHARP. … This report summarizes principal results and conclusions of the research and assessment studies as related to microwave powering of high altitude unmanned airplanes. Other studies defined telecommunications missions and assessed their commercial viability"--Abstract, page 1.
