to four stations at known locations by broadcast signals at known times. This data source allows for tracking of aircraft that are not equipped with ADS-B transponders. OCEANIC: Oceanic position data from the FAA is reported for all major trans-oceanic routes (Atlantic and Pacific). ADS-C: The source of data here is an aircraft broadcasting its position at fixed intervals, typically between 5 and 30 minutes. Data is exchanged between the ground system and the aircraft, via a data link, specifying under what conditions ADS-C reports would be initiated, and what data would be contained in the reports. HFDL: These position reports are received from a High Frequency Data Link system, where air traffic controllers can communicate with pilots over a datalink connection. Aircraft and ground stations make use of high frequency radio signals in order to communicate. FLIFO: This data is provided by several external sources such as airports and airlines. This commercial data includes the departure time, arrival time, origin airport, destination airport, among other parameters. ASDE-X: Data from ASDE-X is received from a surface movement radar located in an airport's ATC Tower or remote tower, multilateration sensors, ADS-B sensors, terminal radars, the terminal automation system, and from aircraft transponders. It is provided by the FAA. Products & services Website & app The Radarbox website is a platform that provides flight tracking information of general aviation and commercial flights.

Fleet Tracker & Airport View The Radarbox Fleet Tracker is tracking solution designed for fleet managers & owners to monitor and better manage their fleet of aircraft. In addition to viewing all active flights and statuses, fleet managers can view flight history for up to 365 days. Advanced aircraft statistics of a fleet such as total flight hours, average flight duration etc. can also be accessed. The Airport View tool displays the live inbound (arrivals) and outbound flight traffic (departures) of a single airport within a single window. It is an excellent secondary tracking resource for Air Traffic Controllers and plane spotters. Airport View also displays the prevailing weather conditions at an
