TELECOMMUNICATION SATELLITE, BEAM FORMING METHOD, AND METHOD FOR MANUFACTURING A SATELLITE LOAD

摘要

The present invention relates to a telecommunications satellite (20) for placing in terrestrial orbit, comprising an antenna comprising a reflector (51) and a network (52) of sources (53). Further, said satellite has adaptive analog beam forming networks (54), said adaptive analog beam forming networks being connected to respective source groups different from the source array (53). Each adaptive analog beamforming network (54) is adapted to simultaneously activate a predetermined number of beams serving respective geographic areas (70) within a geographic region (60, 61) on the surface of the Earth. Each source group has sources (53) shared with other source groups, and at least one geographic region has a geographic overlap of at least 30% with other geographic regions.
