High Quality Content by WIKIPEDIA articles! AirNav RadarBox is a Windows PC software and hardware package which allows appropriately equipped aircraft to be seen on a simulated radar screen. A small receiver connects to the PC via USB and aircraft are detected using the small supplied antenna. By decoding ADS-B (Automatic Dependent Surveillance Broadcast) transmissions from aircraft, those aircraft are displayed on a computer in a similar display to that used by Air Traffic Control. Flight number, aircraft type, altitude, heading, speed are visible and updated every second. The RadarBox system can be used at any location, either as a stand-alone system, or connected to the Internet which allows additional functions. An internal map database provides 3D multi-window maps with worldwide coverage and geographic points which include airports, runways, VOR, NDB, Fixes, cities, roads, airways and elevation data.
