Abstract
A system for sea navigation which features a plurality of ships located in a single high density area (for example port) and a control center for this area using a common transmission channel. The ships are equipped to transmit data about their speed, heading and position, which are displayed on a panoramic screen fitted on all ships and in the control center. The control center has priority access to this common channel to send general interest messages or special messages to all or some of the equipped ships.
