Manufacturing, launching, and operation of satellites are costly. An alternative to satellites could be pilotless aircraft. This would be cheaper. However, aircraft cannot fly for a long time without refueling.A proposed solution is to provide an aircraft with an engine whose energy source is located on the earth. The source transmits energy to the aircraft in the form of microwaves. Such an aircraft may fly 6 to 12months without refueling.Canada. Ministry of Communications. Nauka I Technika.
