Abstract

The object of the invention is a high performance satellite telecommunication method which minimises the costs of using space resources by means of a technique which includes adding, in the frequency band of a satellite repeater or repeater portion used for broadcasting an analog or digital television programme, telecommunications signals that are characterised by the spread spectrum modulation of the information carried by said signals, by a frequency offset of their carriers in relation to the television signal carrier, by the use of a frequency band that minimises the influence of said telecommunication signals on the performance of the television programme broadcasting and that also reduces the interference introduced by the modulated television signal into the telecommunication signals, and by a substantially normal division of the power associated with the space segment used for broadcasting said television programme, between the telecommunication signals and the modulated television signal.
