Abstract

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 utilises 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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 156 words
1) A satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of satellite transmission capacity, of the type wherein a number of earth stations are linked to a satellite on board which regeneration of the earth-to-satellite signal is brought about: characterised in that it features a modular beam switching pattern and utilises asynchronous type protocol procedures in allocation of the satellite transmission capacity between the various earth stations, both for bursts exchanged between earth traffic stations and master station carrying telephone conversations and video conferences, wherein recognition and recovery of bursts transmitted by a given DSI station can be effected by the DSI receiving station with control retained by the same DSI transmitting station, which enables attachment of a preamble to such bursts, and for remote control of an on-board switching matrix (2) which in turn controls the overall system; and in that the system in its entirety is controlled by microprocessors of requisite capacity.
Claim 2
Dependent Claim 156 words
1) A satellite telecommunications system featuring multi-beam coverage and dynamically controlled allocation of satellite transmission capacity, of the type wherein a number of earth stations are linked to a satellite on board which regeneration of the earth-to-satellite signal is brought about: characterised in that it features a modular beam switching pattern and utilises asynchronous type protocol procedures in allocation of the satellite transmission capacity between the various earth stations, both for bursts exchanged between earth traffic stations and master station carrying telephone conversations and video conferences, wherein recognition and recovery of bursts transmitted by a given DSI station can be effected by the DSI receiving station with control retained by the same DSI transmitting station, which enables attachment of a preamble to such bursts, and for remote control of an on-board switching matrix (2) which in turn controls the overall system; and in that the system in its entirety is controlled by microprocessors of requisite capacity.
Claim 3
Dependent Claim 32 words
2) System as in claim 1 wherein remote control of the on-board switching matrix (2) is implemented by a number of memories controlled by a microprocessor (1), adopting an appropriate protocol procedure.
Claim 4
Dependent Claim 36 words
3) System as in claim 1 wherein conversation between the master station and traffic stations is handled by the distribution of appropriate maps through a signalling channel, for which purpose a further protocol procedure is adopted.
