First Claim
Patent Images
1. A collision-avoiding navigational method for an equipped sea-going vessel, comprising the steps of:
- automatically and continuously transmitting a periodic encoded data signal by said equipped sea-going vessel relating to said vessel'"'"'s absolute geographic position, course and speed, wherein the periodic encoded data signal has a random periodicity;
receiving encoded data signals from other equipped sea-going vessels related to said other vessels'"'"' absolute geographic position, course and speed, said other equipped sea-going vessels being within a predetermined radial distance from said equipped sea-going vessel;
detecting a geographic position of not equipped sea-going vessels by radar;
detecting fixed obstacles by radar;
displaying information contained in the encoded data signals received from said other equipped sea-going vessels on a panoramic type of screen, said information being visualized by symbols corresponding to each of said other equipped sea-going vessels;
displaying a position of said equipped sea-going vessel with a first symbol on the panoramic type of screen;
displaying said other equipped sea-going vessel'"'"'s absolute geographic position with second symbols on said panoramic type of screen;
displaying said not equipped sea-going vessels geographic position, as detected by said radar, with third symbols on said panoramic type of screen;
displaying the course and speed of said other equipped sea-going vessels symbolically on said panoramic type of screen; and
displaying the fixed obstacles on said panoramic type of screen.

Abstract
A collision avoidance system for sea navigation comprises, for each equipped ship, a transmitter that repeatedly transmits the geographic coordinates, course and speed of its own ship and a receiver that sends a display device similar data received from other ships. These received data are displayed, mostly in the form of symbols, on the panoramic screen of the display device.
