A system for navigation and collision avoidance where aircraft and vessels determine their position by GPS and report that position to a system of satellites along with local parameters such as heading and attitude. This system of satellites allows communication and exchange of information between all the satellites. Each participating craft receives from at least one of these satellites the positions, headings, speed and other parameters of all craft in the system or of all craft in the vicinity. A display can display a situation or a view located on any craft in the system (but normally on the craft where it is located) to inform o hazards and pending collisions. Icons and craft information appear for all craft being displayed.
