Title
(EN) APPARATUS FOR TRACKING MOVING SATELLITES
(FR) APPAREIL DE POURSUITE DE SATELLITES A DEFILEMENT
Abstract
(EN)
The invention concerns an apparatus for tracking moving satellites, characterised in that it comprises at least a set of independent transmitting and/or receiving primary sources (6) arranged in the proximity of the apparatus focusing surface (5). Said primary sources (6) are coupled with switching means (21, 23, 30, 32, 40, 41, 42, 43) or selecting in the course of operation a first source associated with a focal point corresponding to a first satellite and a second source associated with a focal point corresponding to a second satellite. The invention is particularly useful for tracking moving satellites.
(FR)
L'invention concerne un appareil de poursuite de satellites à défilement. Elle est caractérisée en ce que ledit appareil comporte au moins un ensemble de sources primaires (6) émettrices et/ou réceptrices indépendantes et agencées au voisinage de la surface de focalisation (5) de l'appareil. Lesdites sources primaires (6) sont couplées à des moyens de commutation (21, 23, 30, 32, 40, 41, 42, 43) qui permettent en fonctionnement la sélection d'une première source associée à un point focal correspondant à un premier satellite et une seconde source associée à un second point focal correspondant à un second satellite. Application particulière au domaine de la poursuite de satellites à défilement.
