Satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of the satellite transmission capacity
First Claim
1. A micro-processor controlled satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of satellite transmission capacity, wherein a number of earth stations are linked by a modular beam switching pattern to a satellite which provides on board regeneration of the earth-to-satellite signal, said system comprisingat least one satellite and a plurality of earth stations each comprising a sending and receiving station, one each of said sending and receiving stations being at least a digital speech interpolation station.asynchronous type protocol procedures adopted for allocation of the satellite transmission capacity between the various earth stations,a master station,signal bursts exchanged between earth traffic stations and with said master station according to said asynchronous protocols, wherein recognition and recovery of bursts transmitted by a given digital speech interpolation station can be achieved by the digital speech interpolation receiving station with control retained by the same transmitting station, according to a remote control signal in the form of a preamble attached to each said burst, andan on-board switching matrix remotely controlled according to said bursts and preambles, with reference to said asynchronous protocols, and which in turn controls the overall system

Abstract
The invention relates to a satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of the satellite transmission capacity, of the type where a number of earth stations are linked to a satellite on board which regeneration of the earth-to-satellite signal is brought about. The system also features a modular beam-switching pattern and utilizes asynchronous protocol procedures for the exchanges between earth traffic stations and master station relative to telephone conversations and videoconferences, and for remote control of an on-board switching matrix (2) which operates the system, that is, allocates the satellite'"'"'s transmission capacity so as to serve all the earth stations.
