PROBLEM TO BE SOLVED: To reliably receive a radio signal from a satellite not only by a fixed station but also by a mobile station without providing a large-scale facility even in a blind area unable to directly receive the radio signal from the satellite.;SOLUTION: A gap-filler GFa is disposed at a roof of a building, etc. to receive and amplify a broadcasting signal transmitted from a geo-stationary satellite SAT1, and to relay and transmit the broadcasting signal having the same frequency is as the broadcasting signal received from the geo-stationary satellite SAT1 to the blind area by using a directional antenna.;COPYRIGHT: (C)2004,JPO
