Abstract:
1. A satellite telecommunication system comprising: an antenna capable of communicating with only one satellite selected from a plurality of satellites in stationary orbits, said antenna comprising a planar structure array antenna with a scanning beam, said planar structure array antenna comprising an array of radiant elements, said radiant elements being adapted to be individually supplied by convenient amplitude and phase signals in order to obtain a radiation diagram having a main radiation lobe with, on the horizontal plane, a first amplitude between 1 and 2 degrees, and, on the vertical plane, a second amplitude, such as to ensure an adequate gain to enable the reception of signals from said one satellite selected from the plurality of satellites by a satellite telecommunication system positioned in a land station located within a meridian arc corresponding to said second amplitude on the vertical plane, without the necessity of changing an elevation angle of said antenna.
