Abstract
The invention relates to a system of antennas for tracking nonsynchronous satellites (21, 22) along predefined trajectories.It is characterized in that the said system includes at least first (11) and second (12) transmitter/receiver elements moving in the vicinity of the focusing surface of the system (1) along a line of focal points, the first element (11) actively tracking a first satellite (21) and the second element (12) standing by to actively track a second satellite (22).Particular application to the tracking of nonsynchronous satellites, in particular low- and mid-orbit satellites, and of geostationary satellites.
