MLAT allows for older types of aircraft to transmit data to four receivers who then analyze the data and then measure the Time Difference of Arrival (TDOA) to determine the aircraftвЂ™s speed and location. ADS-B, while robust and reliable, must rely on the aircraft transmitting the data and a receiver picking up this data. As a redundancy, FlightRadar24 additionally relies on MLAT and tracking information from the FAA. Why ADS-B?ДЇlightRadar24 relies on ADS-B technology because it is the most accurate technology available to track commercial flights.

Since FlightRadar24 is not able to provide oceanic receivers to track intercontinental flights, it partners with GPS and other satellite receivers to pick up and relay ADS-B signals during oceanic flights вЂ“ allowing for continuous coverage over land and sea. ADS-B is able to broadcast up to 450km away from the aircraft, which, while robust, would not reach from the middle of a transatlantic flight to land. While FlightRadar24 says their best coverage exists in Europe and the United States (with 80 percent of European flights using ADS-B, and 60 percent of US flights using the same technology), their tracking is also able to provide robust coverage of Canada, the Middle East, Oceania, South America, and countless other locations.ДЇlightRadar24 is also not only confined to continental flights. This lionвЂ™s share of receivers allows FlightRadar24 to paint the most robust and accurate picture of flights tracked around the world. While there are more than 17,000 ADS-B receivers worldwide, FlightRadar24 owns 9,000 of them alone вЂ“ far more than any other additional flight tracking software.

These FlightRadar24 receivers continuously update FlightRadar24 with changes to altitude, speed, location, and route of any commercial flight that broadcasts in ADS-B. In the years since 2006, FlightRadar24 has built an array of over 9,000 receivers that have been set up by a network of flight tracking volunteers. It broadcasts its location openly вЂ“ a critical notion as it allows any ADS-B interpreting receiver to receive and interpret communications from this aircraft.ДЄs ADS-B is an open broadcast, FlightRadar24 can rely on the data being broadcast directly from the planes themselves. It is considered automatic because it is the onboard broadcast which creates the transmission no external source is required. ADS-B, which stands for Automatic Dependent Surveillance вЂ“ Broadcast, is a type of transmission that broadcasts flight information directly from the aircraft to transponders, instead of relying on external forms of tracking such as radar. These volunteers, passionate about contributing to flight tracking, provide the backbone of received flight data that FlightRadar24 presents in real time.ДЇlightRadar24 receives broadcasts from ADS-B transponders on aircraft. FlightRadar24 relies on over 9,000 ADS-B receivers that were often installed by volunteers in their homes or apartments all around the world.

This data is then intercepted by the 9,000 receivers world wide, where the data is then converted into usable data, which is plotted against a map in real time to provide visual updates on any commercial aircraft, worldwide.ДЇlightRadar24 is an easily accessible software, open to use by anyone who has access to a smartphone, computer, or tablet with an internet connection.ДЇlightRadar24 was started in 2006 as a small-scale hobby and passion project by two Swedish brothers who originally built the site to monitor flight data in Central and Northern Europe, before expanding it to relay global flight data. FlightRadar24 operates by utilizing a technology called ADS-B, which revolves around aircraft broadcasting their location, altitude, and speed. As of 2019, it features over 9,000 receivers tracking well over 32,000 aircraft in 190 countries. FlightRadar24 is the leading flight tracking service offered around the globe.
