Abstract : According to the Patent a natural gigantic loop antenna is created by the earth's magnetosphere in combination with a satellite having long insulated conductors ending in a metallic plate. The satellite may be equipped with a transmitter and relay equipment capable of transmitting in the Extra Low and Ultra Low frequency range. These waves are transmitted efficiently by the huge antenna and may be received above, on, or penetrate below the surface of the earth. Such waves may be used to carry communications or for other purposes such as transmission between a satellite and a submarine.
