Multilateration (MLAT)

Multilateration, within the context of aviation, is a technique employed to determine the location and direction of an aircraft utilizing the time difference of arrival (TDOA) of radio signals originating from the aircraft. In order to employ this method, the presence of four or more Flightradar24 receivers within the region is required to gather a signal emanating from the same aircraft. Utilizing this data gathered from the radio signals, the TDOA is calculated, thereby giving the necessary information that can be analyzed to determine the aircraft’s position and heading. This technique is a key component of modern air traffic control systems, providing critical information that can be used to navigate the airspace and ensure the safety of all personnel involved. It allows for precise tracking and monitoring of aircraft movement, enabling ground controllers to allocate routes, direct traffic and flights, as well as providing valuable data for investigations and analysis.
