Typical ADS-B receivers include Kinetic Avionic's SBS-1 and AirNav-systems's AirNav and these receivers are run by volunteers, mostly aviation enthusiasts. Airbus aircraft are ADS-B equipped but Boeing 707, 717, 727, 737-200, 747-100, 747-200, 747SP do not come equipped and are not generally visible unless retrofitted by their operators. As of 2019, about 80% of aircraft in Europe are equipped with ADS-B and 60% in the US. The aircraft-based transponders use the GPS and other flight data input to transmit signals containing aircraft registration, position, altitude, velocity and other flight data. The principal source is a large number of ground-based ADS-B receivers, which collect data from any aircraft in their local area that are equipped with an ADS-B transponder and feed this data to the internet in real time. Automatic dependent surveillance – broadcast (ADS-B).Tracking įlightradar24 aggregates data from six sources: Initially, the site crashed due to the sheer number of users. The website processed 76,200,000 requests related to the flight over its course. In September 2022, the plane carrying the coffin of Queen Elizabeth II was attempted to be tracked by 6,000,000 users in the first minute after the transponder activated, with 4,790,000 following a portion of the flight, becoming the most tracked flight of all time. In August 2022, the plane carrying Nancy Pelosi to Taiwan, SPAR19, became the most tracked flight to date, tracked by over 708,000 people as it landed in Taipei, with over 2,900,000 following at least a portion of the flight. In March 2022, the site was used to see the playback of the crash of China Eastern Airlines Flight 5735. In February 2022, during the Russian invasion of Ukraine, the website crashed due to an influx of visitors tracking flights in and around Ukraine. Aircraft located using satellite data are coloured blue on the map, and yellow if located by terrestrial receivers.

įrom 3 March 2020, ADS-B data collected by satellite was made available to all users. In November 2015, The Guardian newspaper reported that Metrojet Flight 9268 en route to Saint Petersburg from Sharm el-Sheikh International Airport had broken up in the air based on information available from Flightradar24. Flightradar24 reported that its web traffic increased to around 50 times normal, which caused some access congestion to users. In 2014, it was used by multiple major news outlets following several high-profile crashes: in March after the disappearance of Malaysia Airlines Flight 370, in July after Malaysia Airlines Flight 17 was shot down over Ukraine, and in December when Indonesia AirAsia Flight 8501 went missing. Flightradar24 came at the turn of the month July-August 2010 as an iOS application. The service received extensive exposure in 2010, when international media relied on it to describe the flight disruption over the North Atlantic and Europe caused by the Eyjafjallajökull volcano eruptions. The service was opened in 2009, allowing anyone with a suitable ADS-B receiver to contribute data. The service was founded by two Swedish aviation enthusiasts in 2006 as and later Flygradar.nu for Northern and Central Europe. The Guardian considers the site to be 'authoritative'. The service is available via a web page or mobile device apps. It aggregates data from multiple sources, but, outside of the United States, mostly from crowdsourced information gathering by volunteers with ADS-B receivers and from satellite-based ADS-B receivers. It can also show time-lapse replays of previous tracks and historical flight data by airline, aircraft, aircraft type, area, or airport. It includes flight tracking information, origins and destinations, flight numbers, aircraft types, positions, altitudes, headings and speeds.
