A communication system (1) has at least one communication devices (20-22) and a control device (10) joined to one of the communication devices for exchange of text information. The connection between the communication device and the central device is via at least one satellite (30), and the data transmitted from the communication devices contains additional instructions concerning the actual position of the communication device, or data transmitted from the central device includes additional information about the relevance of the text information. An independent claim is included for a method for exchange of text information.
