Arrangement and method for flight security and/or air traffic control of aircraft

摘要

The arrangement has receiving stations (20) staying in connection with a flight security and/or air-traffic control central station (11). A part of the receiving stations is designed as satellite i.e. low earth orbit (LEO) satellite, receiving stations, such that the receiving stations receive a 1090 megahertz broadcast signal (5) transmitted by a transmission station (3) designed as a mode S extended squitter. A part of data contained in the signal is transmitted via a radio transmission route (21) to a satellite ground control station (22) and to the central station or other organizations. An independent claim is also included for a method for flight security and/or air-traffic control of an aircraft.
