How to Track Flights Live

Most aircraft carry an ADS-B transponder that broadcasts the plane's GPS position, altitude, speed, heading, and callsign roughly twice a second. These broadcasts are unencrypted and receivable by anyone with an inexpensive antenna — and networks of volunteers feed them into public tracking maps.

That's why live flight tracking exists at all: the data is a byproduct of air-traffic safety, published openly by the aircraft themselves.

A good tracker shows each aircraft's live position, altitude, ground speed, heading, aircraft type, registration, and origin/destination when known. You can filter by altitude or aircraft type, replay recent tracks, and click any plane for its details.

Coverage is excellent over land in populated regions and thinner over oceans and remote areas, where fewer receivers (or satellite ADS-B) fill the gaps. Some military and sensitive flights don't broadcast or appear with limited data — that's normal.

The most common reason is the most ordinary: waiting for someone at the airport. Live tracking beats the departure board — you can see the inbound aircraft's actual position and estimated arrival instead of a gate agent's guess.

Aviation enthusiasts track interesting traffic — rare aircraft types, diversions, holding patterns during storms, and the daily rhythm of hubs. Researchers and journalists use the same data to follow logistics, from cargo routes to disaster-relief flights.

WorldEye's free map includes live flight tracking on the 3D globe: aircraft positions update in real time, and you can click any flight for its telemetry. No account, no signup — open the map and the sky is already there.

Tip: zoom into a major hub and watch arrivals sequence themselves. Then cross-reference with a live airport webcam from the camera layer. Two public data sources, one picture — that's the OSINT habit in miniature.
