SATELLITE BROADCASTING SYSTEM, TERRESTRIAL TRANSMITTER, GAP FILLER DEVICE, BROADCASTING RECEIVER, AND METHOD FOR SATELLITE BROADCASTING

摘要

PROBLEM TO BE SOLVED: To ensure that not only fixed stations but also mobile stations can receive radio signals from a satellite even in a dead area where these signals cannot be received directly, without installing large-scale equipment.

SOLUTION: A gap filler device GFa is installed on the roof of a building or the like. The device GFa receives and amplifies broadcasting signals transmitted from a geostationary satellite SAT1. The received signals are relayed to a dead area using a directional antenna at the same frequency as that of broadcasting signals from the geostationary satellite SAT1.
