After 6 years of service our repaired Flight Radar 24 receiver is located at the wagoner’s gap site.


Flightradar24 operates the world’s largest network of ADS-B/Mode S receivers. This network, together with government air traffic control and other data sources, is how Flightradar24 is able to track aircraft around the globe.


ADSB  – Automatic Dependent Surveillance–Broadcast is a surveillance technology in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts it, enabling it to be tracked.

Mode-S employs airborne transponders to provide altitude and identification data, with Automatic Dependent Surveillance Broadcast (ADS-B) adding global navigation data typically obtained from a Global Positioning System (GPS) receiver. The Mode S is a secondary surveillance and communication system which supports Air Traffic Control (ATC). Each Mode S transponder equipped aircraft is assigned a unique address code. Using this unique code, interrogations can be directed to a particular aircraft and replies can be unambiguously identified.

The aircraft ADSB transmissions use 4.6 MHz of bandwidth centered on the frequency 1090 MHz
