Abstract
The invention concerns an antenna system including at least two antennas (10, 11), each of said antennas (10, 11) being capable of pointing independently of the other(s) in any direction within a solid angle. According to the invention, the antennas (10, 11) are mounted on a common support (17) co-operating with rotation means (18) for rotating the common support (17), the rotation means (18) being activated to prevent masking of one of the antennas (10, 11) by another of the antennas (10, 11). The invention applies in particular to tracking non-geostationary satellites.
