| 20100088729 | Microwave frequency satellite signal reception installation - The present invention relates to an installation for receiving microwave frequency radio satellite signals, said installation comprising a first electric adder to add a first electrical signal representative of a radio signal according to a first polarization and transposed to a first intermediate band and a second electrical signal representative of a radio signal according to a first polarization and transposed to a second intermediate band and a second electric adder to add a first electrical signal representative of a radio signal according to a second polarization and transposed to the first intermediate band and a second electrical signal representative of a radio signal according to a second polarization and transposed to a second intermediate band. | 04-08-2010 |
| 20090270088 | Telecommunication network - The present invention concerns a telecommunication network for establishing radiofrequency links between at least one gateway and ground terminals via a multispot telecommunication satellite. The network includes a service zone composed of a plurality of cells each including a plurality of ground terminals, the said service zone being split into N sub-zones, N being an integer strictly greater than 1, each sub-zone having a capacity profile evolving in time over a given period and presenting a maximum value, the said maximum values of each of the capacities being shifted with regard to time and a multispot satellite including a transponder including amplification of the signals emitted by the gateway on the forward link and the signals emitted by the cells on the return link and a continuous power supply system of the amplifier. The said supply system includes means for supplying the amplifier providing the whole of the sub-zones with their respective capacity profile evolving over the said given period, the maximum continuous power delivered by the supply system being less than the continuous power which the amplifier would consume to provide simultaneously the whole of the sub-zones with their maximum capacity value. | 10-29-2009 |
| 20090239529 | Telecommunication network - The present invention relates to a telecommunication network for establishing radiofrequency links between gateways and ground terminals via a telecommunication satellite with several spot beams, known as a multispot satellite. The network includes a multispot satellite including a payload for the reception, processing and retransmitting of telecommunication signals received by said satellite, a service area comprised of a plurality of basic coverage areas, known as cells, each cell including a plurality of ground terminals and a plurality N | 09-24-2009 |
| 20090232046 | Communication network - A telecommunication network for establishing radiofrequency links between gateways and ground terminals via a multispot satellite, the network comprising a multispot satellite, a plurality of gateways, each gateway establishing a link with the satellite on at least Ns link channels corresponding to Ns frequency intervals [f | 09-17-2009 |
| 20090109853 | Method for the optimization of the payload of a multispot telecommunication satellite - A Method for the optimization of the payload of a multispot telecommuncation satellite is disclosed. This type of satellite allows the use of several antenna spots on board the satellite to cover contiguous geographical zones, instead of a single broad spot. The method uses the division of an amplification unit such as a travelling wave tube TWTA between several spots. | 04-30-2009 |
