METHOD FOR TEMPORALLY SYNCHRONIZING AN ORTHOGONAL FREQUENCY EVACUATION WAVY FORM AND DECENTRALIZED TRANSIT TIME MANAGEMENT SATELLITE RADIOCOMMUNICATION SYSTEM.

摘要

The invention relates to a method for temporally synchronizing an orthogonal frequency evasion waveform. The method comprises for each station a step of acquiring and maintaining the time, the time thus determined being a time estimated locally at each station and a step of acquiring and maintaining the transit time between the station and a station. satellite, the transit time being estimated locally. The times of emission by said station are determined according to the locally estimated time and the estimated transit time locally. The invention further relates to a satellite radio system with decentralized transit time management. In particular, the invention applies to satellite communications whose waveform uses spread spectrum and frequency hopping techniques in general, and more particularly to transparent geostationary satellite communications.
