Patent

CA 2199884

A spacecraft of a set of spacecraft has an antenna support frame defining square apertures, which are the same size in all spacecraft of the set of spacecraft. The set also includes a plurality of radiating tiles for various operating frequencies. The tiles all have the same dimensions, so that any combination of tiles may be mounted in the apertures of the frames of any spacecraft to form antenna arrays of various sizes, depending upon the customer's requirements. Each tile includes plural beamformers and power amplifiers, and remotely controllable phase shifters and level controls, for ready reconfiguration of the antennas while the spacecraft is in operation. The preferred dimension of each radiating tile is a one-foot square.

Engin spatial d'un ensemble d'engins spatiaux doté d'un bâti d'antennes définissant des ouvertures carrées, qui sont de dimensions identiques dans tous les engins spatiaux. L'ensemble d'engins spatiaux comprend aussi plusieurs carreaux rayonnants correspondant à différentes fréquences de fonctionnement. Tous les carreaux ont les mêmes dimensions, ainsi n'importe quelle combinaison de carreaux peut être fixée dans les ouvertures du bâti de n'importe quel engin pour former des réseaux d'antennes de différentes grandeurs, selon les exigences du client. Chaque carreau comprend plusieurs formeurs de faisceaux et amplificateurs de puissance, et des déphaseurs et régulateurs de niveau télécommandés, pour une reconfiguration facile des antennes pendant que l'engin spatial est en marche. La dimension préférée d'un carreau rayonnant est un carré d'un pied de côté.
