  • Page 9: Section 1 System Description

    SECTION 1 SYSTEM DESCRIPTION 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).

  • Page 10: Ads-B In

    These broadcasts contain much more data than just a simple position report, they include: identity (Flight ID/Tail Number, ICAO registration number, etc), ground track, ground speed, pressure altitude, indications of equipment capabilities, and emergency status.
