Claim:
1. A broadband multi-beam satellite radiocommunication system configured for complete or fractional re-use of frequencies from a total band BT allocated to an uplink, comprising a satellite having a multi-beam receive antenna configured to form a set of at least two adjacent reception spots of a terrestrial coverage; and a set of transmitter terminals distributed across all of the spots, each terminal including geographical positioning means and means for transmission of an allocated transmission resource; an uplink transmission resource scheduler and allocator, taking the form of one or more electronic computers, configured to allocate a transmitter terminal on demand an uplink transmission resource in terms of a frequency sub-band as a function of the geographical position of the transmitter terminal and a transmission resource allocation plan in accordance with which, each reception spot consists of a central inner zone and a peripheral zone surrounding the central inner zone; and the same continuous or discontinuous principal band BP of frequencies forming a part or the whole of the total band is allocated in its entirety to each central inner zone, wherein in accordance with the transmission resource allocation plan, the principal band BP is divided into a first bundle comprising a first whole number n1, greater than or equal to 2, of adjacent or separate principal sub-bands each of which is continuous; and the central inner zone of each reception spot is divided, except for a scale factor representative of the size of the central inner zone, into the same regular cellular pattern of cells wherein the various principal sub-bands of the first bundle are unitarily distributed, the number of cells of the cellular pattern being equal to the first number n1 of principal sub-bands of the first bundle.
