| a radio station located either on the Earth's surface or within the major portion of the Earth's atmosphere and intended for communication:
- with one or more space stations; or
- with one or more other stations of the same kind by means of one or more reflecting satellites or other objects in space
Note 1 – Where the term "earth station" is used without qualification, it may be presumed to refer to an earth station at a fixed location which is not used, primarily, for communication with mobile earth stations.
Note 2 – In French, the terms "station terrienne", "station terrestre" and "station de Terre" refer to different concepts, namely "earth station", "land station" and "terrestrial station", respectively.
