Every airliner, business jet and helicopter that broadcasts ADS-B can be followed live. Earth Live draws them on a 3D globe with their heading, altitude and speed; tap one to follow it with the camera.
Aircraft broadcast their position, altitude and speed by ADS-B about once a second. Thousands of volunteers receive those signals and share them through the open adsb.lol network. Zoom in on the globe to load every aircraft within about 460 km of the centre; military aircraft are shown worldwide at any zoom. Colour shows altitude, and an aircraft squawking 7500, 7600 or 7700 (hijack, radio failure, emergency) turns red.
Callsign, aircraft type and registration, altitude, ground speed, track, climb or descent rate and squawk code, plus a link to the flight's history. Between updates the globe moves each aircraft along its heading at its speed, so traffic flows smoothly.
