Seeing the Unseen: Live Radar 24 Feeds Expose Real-Time Flight Data
By Chloe Bennett
Not all aircraft in civilian airspace broadcast precise GPS coordinates. Older regional jets, military cargo transports, and light general aviation planes frequently run older Mode A or Mode S transponders. These units broadcast identity and altitude without latitude and longitude. To prevent these aircraft from vanishing entirely from public observation, modern monitoring networks lean heavily on multilateration MLAT tracking.
MLAT operates on a geometric principle known as Time Difference of Arrival (TDOA). When an aircraft emits an omnidirectional Mode S ping, the signal travels outward at the speed of light: roughly 299,792 kilometers per second. Four or more ground stations in the local network intercept the exact same transmission at slightly different microsecond intervals. By measuring the minute fractions of time elapsed between these receipts, central processors calculate mathematical hyperbolas whose intersection reveals the aircraft’s precise three-dimensional fix.
This technique demands extreme synchronization. A timing error of a single microsecond skews an aircraft's calculated position by approximately 300 meters. Ground stations use precision GPS clock synchronizers to maintain nanosecond-accurate internal clocks. Thanks to these calculations, flight paths that lack native GPS broadcasts remain trackable with remarkable precision through congested terminal areas and along complex approach corridors.
