Abstract:
1. Telecommunications system, intended for low-throughput data transfer between at least two users located substantially on the surface of a celestial body, comprising: at least two transmitting/receiving surface terminals, each associated with a different user, one or more stationary means GEO above the surface of the celestial body, these stationary means being able to transmit data from and to a predefined coverage area with a line of sight to the stationary means, and one or more signal repeater to repeat signals transmitted and/or received from the stationary means GEO and the surface terminals, said repeater traveling above the surface of the celestial body and comprising means of performing an amplification without frequency translation of the signal received from the stationary means GEO; a same frequency band being used for communications between the surface terminals and the repeater and for communications between the repeater and the stationary means; and wherein at least one user terminal utilizes a CDMA type interface to manage arrival of two signals bearing Doppler and delay differences.
