Abstract
A ground-based beam-forming system includes a satellite and a ground-based processing base equipped with beam-forming means. The satellite is equipped with first transmission/reception means for sending and receiving analog signals with remote terminals, and second transmission/reception means for sending and receiving signals with ground-based third transmission/reception means communicating with the processing base. The satellite includes digitizing means suitable for converting analog signals received by the first transmission/reception means into digital signals, the digitizing means being directly connected to the first transmission/reception means.
Claims21
A ground-based beam-forming system comprising:
- a satellite;
- and
- a ground-based processing base equipped with beam-forming means, said satellite being equipped with first emission/reception means for sending and receiving analog signals with remote terminals and second transmission/reception means for sending and receiving signals with ground-based third emission/reception means communicating with said processing base, wherein the satellite comprises:
- digitizing means suitable for converting analog signals received by the first emission/reception means into digital signals, said digitizing means being directly connected to the first emission/reception means;
- and
- digital processing means directly connected to the digitizing means, wherein the processing base comprises beam-forming means and processing means connected to said third emission/reception means.
A ground-based beam-forming system comprising a satellite and a ground-based processing base equipped with beam-forming means , said satellite being equipped with first emission/reception means for sending and receiving analog signals with remote terminals, and second transmission/reception means for sending and receiving signals with ground-based third emission/reception means communicating with said processing base, wherein the satellite comprises:
- conversion means suitable for converting digital signals received by the second emission/reception means into analog signals, said conversion means being directly connected to the first emission/reception means ;
- and
- digital processing means directly connected to the conversion means,
- wherein the processing base comprises beam-forming means and processing means connected to said ground-based third emission/reception means.
The system as claimed in claim 18, wherein said second emission/reception means comprise a demodulator for demodulating the digital signals received from the ground-based processing base.
