<p>The invention concerns an antenna system, comprising at least two antennae (10, 11), each antenna (10, 11) capable of independently pointing in any solid angle direction. The invention is characterised in that the antennae (10, 11) are mounted on a common support (17) co-operating with means (18) rotating said common support, said rotation means (18) being activated to prevent one of the antennae (10, 11) from being masked by the other antenna (10, 11). The invention is useful for tracking moving satellites.</p> |
