METHOD AND SYSTEM FOR TRANSPORTING SIGNALS IN A SATELLITE SYSTEM

Data transmission system in a communication network, characterized in that it comprises a data modulator comprising: .cndot. a first part (306E) at the level of the collection point part comprising: .cndot. an NCR module (303) taking account of an external absolute time reference to reconstitute a network clock, .cndot. a transmitter module (304) receiving the value of a time reference to be inserted into the data packet to be transmitted and transmitting to the NCR module an information item on an instant of synchronization for the receiver, .cndot. a second part (30FE) at the level of the radiofrequency part of a gateway comprising; .cndot. a receiver module (310), .cndot. a module (311) for reconstructing a clock locally, .cndot. a module (312) for inserting a time reference into a data packet received by the receiver before transmission of the data via the satellite, .cndot. the first part (306E) and the second part (30FE) exchange encapsulated data.
