Patent

CA 2089884

A craft tracking and collision avoidance system is disclosed. The system allows the positions of a plurality of craft (30, 32) either on land, sea, air or space, to be monitored. Each craft (30, 32) determines its own position using an existing position determining system (100) such as LORAN or GPS. Each craft (30, 32) then transmits a radio frequency signal into which position information, preferably identifying information and other messages, have been encoded. Each craft (30, 32) broadcasts its position, identifying information and other messages on a regular basis without the need for any interrogation signal. The broadcast position and identification information can be received by other craft and, since each craft (30, 32) has determined its own position, can be used to determine the proximity and identity of other craft, and if the craft are on a collision course. Preferably, the position of all the craft (30, 32) within a predetermined range (36) of a craft (30) is represented on a display in order to give the craft operator a visual indication of traffic surrounding his craft (30).

Système de poursuite de véhicules et anti-collision. Le système permet de contrôler les positions d'une pluralité de véhicules (3-, 32) sur terre, sur mer, dans les airs ou dans l'espace. Chaque véhicule (30, 32) détermine sa propre position à l'aide d'un système (100) existant de détermination de position tel que LORAN ou GPS. Chaque véhicule (30, 32) émet sa position, des informations d'identification ainsi que d'autres messages sur une base régulière sans aucun signal d'interrogation. Les informations de position et d'identification émises peuvent être reçues par un autre véhicule, et comme chaque véhicule (30, 32) a déterminé sa propre position, on peut utiliser lesdites informations afin de déterminer la proximité et l'identité d'autres véhicules, et si les véhicules se trouvent sur une trajectoire de collision. De préférence, la position de tous les véhicules (30, 32) se trouvant à l'intérieur d'un rayon d'action prédéterminé (36) d'un véhicule (30) est représentée sur un affichage afin de donner au pilote du véhicule une indication visuelle du traffic entourant son propre véhicule (30).
