An airport ground vehicle transmitter developed by ITT Exelis and avionics manufacturer FreeFlight Systems is the first such device certified to a new standard by the U.S. Federal Aviation Administration (FAA). Ground vehicles fitted with the device can be monitored by air traffic controllers, improving “situational awareness” and safety at busy airports. The vehicle movement area transmitter (V-MAT) continuously reports the position of a ground vehicle through automatic dependent surveillance-broadcast (ADS-B) OUT transmissions.
