Automatic Dependent Surveillance Broadcast (ADS-B) is a surveillance technology used in aviation that enables aircraft to automatically broadcast their position, speed, altitude, and other information to ground-based receivers and other aircraft equipped with ADS-B technology. Smart Air Track is a fully redundant ADS-B receiving system with a dual independent channel ADS-B receiver, dual redundant AC power supply, two ADS-B antennas/clamps, two GPS antennas/clamps and four antenna line surge protectors. SmartAirTrack is an ideal solution for receiver sites that require full redundancy or dual antennas that are required due to partially obstructed views.
