Track Your Flight Live

Yes you can track your flight live on the air, like we track our amazon or ups packages. You heard it right, even I got surprised when I came to know about this. There is a website called Flightradar24, This service was started by two Swedish aviation enthusiasts in the year 2006 for Northern and Central Europe only, Later on they expanded their service to the remaining continents. Now this is available in all over the globe. You can even download in your android mobile also Link.

How does it work..?

Flightradar24 is a flight tracker that shows live air traffic from around the world. Flightradar24 combines data from several data sources including ADS-B, MLAT and radar data.

ADS-B

  • The primary technology that Flightradar24 use to receive flight information is called automatic dependent surveillance-broadcast (ADS-B). The ADS-B technology itself is best explained by the image to the right.
  • Aircraft gets its location from a GPS navigation source (satellite)
  • The ADS-B transponder on aircraft transmits signal containing the location (and much more)
  • ADS-B signal is picked up by a receiver connected to Flightradar24
    Receiver feeds data to Flightradar24

MLAT

In some regions with coverage from several FR24-receivers we also calculate positions of non-ADS-B equipped aircraft with the help of Multilateration (MLAT), by using a method known as Time Difference of Arrival (TDOA). By measuring the the time it takes to receive the signal from aircraft with an older ModeS-transponder, it’s possible to calculate the position of these aircraft. Four FR24-receivers or more, receiving signals from the same aircraft, are needed to make MLAT work. MLAT coverage can only be achieved above about 3,000-10,000 feet as the probability that four or more receivers can receive the transponder signal increases with increased altitude.

Radar Data

Radar (Radio Detection and Ranging), is an object detection system that uses radio waves to determine the range, altitude, direction of movement, and speed of objects. The antenna transmits pulses of radio waves or microwaves, which bounce off any object in their path. The object returns a tiny part of the wave’s energy to a dish or antenna.
