It is designed to receive, process, and output traffic (ADS-B air-to-air,and TIS-B traffic information), and weather (Flight Information Service-Broadcast(FIS-B)) information to the G3X Touch system through an RS-232 serial connection orBluetooth connection.ADS-B (Automatic Dependent Surveillance-Broadcast) is a surveillance technologydeployed across the United States as the cornerstone of the FAA’s Next Generation AirTransportation System (NextGen). ADS-B enables improved surveillance services, bothair-to-air and air-to-ground, especially in areas where radar is ineffective due to terrainor where it is impractical or cost prohibitive. Initial applications of air-to-air ADS-B arefor “advisory” use only, enhancing a pilot’s visual acquisition of other nearby ADS-Bequipped aircraft either when airborne or on the airport surface.18,000 FT10,000 FTGPSRADAR ATC1090 ESUATRADARCompositeADS-BGroundStationMode A/C1090 ES1090 ESUAT UATUATADS-B System
