Garmin GTS Traffic Systems are a family of Traffic Advisory Systems (TAS) and Traffic Alert and Collision Avoidance Systems (TCAS). The systems feature both active interrogation of aircraft transponders and reception of 1090 MHz Extended Squitter ADS-B broadcasts (ADS-B In).

These LRU's enhance traffic surveillance features and integrate with the AXIS™ flight displays to provide the pilot with flight identification, position, altitude, velocity and heading information of other aircraft within the area.
