Extra-Terrestrial Relays
Clarke's 1945 technical paper in Wireless World proposing the geostationary communications satellite — the founding document of the satellite-communications industry.
"Extra-Terrestrial Relays: Can Rocket Stations Give World-wide Radio Coverage?" is Clarke's 1945 paper in Wireless World, written when Clarke was a Royal Air Force radar instructor and the space age was still a decade away. The paper proposes placing three satellites in geostationary orbit to provide global radio coverage. The physics is worked out in detail; the engineering requirements are enumerated; the economic value is estimated. Almost every specific prediction in the paper was realized within twenty years.

The paper is short (four pages), written in a style that is technical but accessible, and published in a magazine with a readership in the tens of thousands. Clarke was twenty-seven years old. He did not patent the idea. His later accounts of the decision were matter-of-fact: the concept seemed to him obviously correct; patenting it seemed impossible for someone without resources to enforce; the world would produce the technology whether or not he got credit; producing it faster mattered more than getting credit.
