ABSTRACT:
A system to control sea navigation or traffic of a plurality of ships or moving bodies is disclosed. The system comprises a radio navigation reference system comprising at least two reference beacon sources and a navigation central station M. Said central station M, the reference beacon sources and the ships or moving bodies are provided with a first intercommunication means from said central station M to each reference beacon source, said first intercommunication means being synchronized by said central station M, and a second intercommunication means from said central station and each reference beacon source to each ship or moving body. The system further comprises a third intercommunication means from each ship or moving body to a control station PC, said control station PC having means making it possible, through the computation of the distances from each ship or moving body to said central station M and to each reference beacon source, provided by said third intercommunication means, to compute the position of each ship or moving body with respect to the reference radio navigation system. Said third intercommunication means being tuned on the radio navigation carrier wave. There is provided means for the real-time display of the geographical position of each ship or moving body.
