Abstract:
A transmitting apparatus for use in non-geostationary satellites which is mounted in a non-geostationary satellite of a satellite communications system to carry out intersatellite communication between a geostationary satellite revolving around the Earth along a geostationary orbit separated from the surface of the Earth by a first given distance in a stationary state relative to the surface of the Earth, and said non-geostationary satellite revolving around the Earth along a non-geostationary orbit separated from the surface of the Earth by a second given distance smaller than said first given distance in a non-stationary state relative to the surface of the Earth, and which is equipped with transmitting means which sends a transmitting signal to said geostationary satellite along the path between said non-geostationary satellite and said geostationary satellite, comprising:Earth-sensing means for detecting the presence of the Earth in the direction of transmission of said transmitting signal by said transmitting means to output a detection signal as long as the Earth crosses the direction of transmission of said transmitting signal; andtransmission direction-shifting means which is connected to said transmitting means and said Earth-sensing means and is designed to shift the direction of transmission of said transmitting signal by said transmitting means to a direction which prevents the Earth from being exposed to said transmitting signal as long as said transmission direction-shifting means is receiving said detection signal.
