Abstract
Official abstract text for this publication.
A satellite multibeam telecommunication system includes at least one satellite provided with at least one high-power amplifier, a digital processor, and means for implementing go channel beam hopping, without return channel beam hopping, the digital processor being configured to digitize the return channel beams and aggregate them, the bandwidth of the return channel beams being proportional to the temporal allocation on the go channel beams.
First claim
Opening claim text (preview).
1 . A satellite multibeam (F 1 , F 2 , F 3 , F 4 ) telecommunication system comprising at least one satellite provided with at least one high-power amplifier, a digital processor (PN), and means for implementing go channel beam hopping, without return channel beam hopping, the digital processor (PN) being configured to digitize the return channel beams and aggregate them, the bandwidth of the return channel beams (F 1 , F 2 , F 3 , F 4 ) being proportional to the temporal allocation on the go channel beams (F 1 , F 2 , F 3 , F 4 ). 2 . The system according to claim 1 , wherein the high-power amplifier is a traveling wave tube or a solid state power amplifier. 3 . The system according to claim 1 , wherein the digital processor is a transparent digital processor or a regenerative digital processor. 4 . The system according to claim 1 , comprising, for each return channel beam (F 1 , F 2 , F 3 , F 4 ), an amplifier upstream of the digital processor (PN). 5 . The system according to claim 4 , comprising, for each return channel beam, a frequency converter downstream of the amplifier and upstream of the digital processor (PN). 6 . The system according to claim 4 , comprising, for each return channel beam, a multiplexer downstream of the frequency converter and upstream of the digital processor (PN). 7 . The system according to claim 1 , comprising, in the return channel, downstream of the digital processor (PN), a frequency converter, a power amplifier and a transmission antenna feed, disposed in series. 8 . A method for managing a digital processor (PN) of a satellite of a satellite multibeam telecommunication system with go channel beam hopping and without return channel beam hopping, wherein the return channel beams are digitized and they are aggregated, the bandwidth of the return channel beams (F 1 , F 2 , F 3 , F 4 ) being proportional to the temporal allocation on the go channel beams (F 1 , F 2 , F 3 , F 4 ).
