DATA TRANSMISSION METHOD AND SYSTEM FOR FORMING A GLOBAL EMERGENCY CALL/WARNING SYSTEM ESPECIALLY USING A SATELLITE NAVIGATION SYSTEM SUCH AS GALILEO

摘要

Disclosed is a communication system (1) for advantageous use in a global emergency call/warning system, comprising at least one communication device (20, 21, 22) and a central device (10) that is connected to said communication device (20, 21, 22) in order to exchange text data. The connection between the communication device (20, 21, 22) and the central device (10) is established via at least one satellite (30). Data transmitted by the communication device (20, 21, 22) contains additional information about the current position of the communication device (20, 21, 22), or data transmitted by the central device (10) contains additional information about the local relevance of the text data.
