DATA LINK TRAFFIC (GDL 39/39R) (OPTIONAL)

The GDL 39/39R is a receive-only data link radio with on-board GPS, 978 MHz
(Universal Access Transceiver frequency band), and 1090 MHz Extended Squitter (1090
ES) receivers. 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.
ADS-B (Automatic Dependent Surveillance-Broadcast) is a surveillance technology
deployed across the United States as the cornerstone of the FAA's Next Generation Air
Transportation System (NextGen). ADS-B enables improved surveillance services, both
air-to-air and air-to-ground, especially in areas where radar is ineffective due to terrain
or where it is impractical or cost prohibitive. Initial applications of air-to-air ADS-B are
for "advisory" use only, enhancing a pilot's visual acquisition of other nearby ADS-B
equipped aircraft either when airborne or on the airport surface.
