A system for correlating secondary surveillance radar (SSR) data and ACARS data which results in a real time correlation of data which are unique to the separate existing systems. More specifically, a method is provided to attach flight identification data from ACARS signals to real time SSR data from Mode S transponders. Aircraft Mode S addresses are decoded and then converted to aircraft registration numbers using an algorithm or lookup table. Registration numbers are then correlated with registration numbers from decoded ACARS signals. The result is a real-time system which may provide an aircraft's registration information, including registration number, owner, make, and model, as well as its current flight identification number, and ACARS messages. As part of an aircraft multilateration system, the system provides an independent air traffic control picture complete with aircraft position and identification by flight number without the use of active radar equipment.

1. A method of generating aircraft position and identification information, comprising the steps of:receiving, at a plurality of radio receivers, a first radio signal from an aircraft, the first radio signal including an address corresponding to aircraft identification; generating, at each of the plurality of radio receivers, a time stamp indicating when the first radio signal is received at each of the plurality of radio receivers; transmitting data contents of the radio signal and the time stamp to a central workstation; generating aircraft position data by measuring differences in time of arrival of the first radio signal between at least two of the plurality of the radio receivers; generating aircraft identification data from the address corresponding to aircraft identification; receiving a second radio signal from the aircraft, the second radio signal containing aircraft identification information; and correlating aircraft identification information from the second radio signal with aircraft identification information from the first radio signal to confirm identity of the aircraft.
