1.2.2 ADS-B System Overview
The Automatic Dependent Surveillance-Broadcast (ADS-B) improves situational awareness and flight
safety by providing real time traffic information. The ADS-B In function is used to receive ground station
supported TIS-B and ADS-R traffic, and direct communication with nearby like equipped aircraft (with
Mode S or UAT). The ADS-B Out (1090ES) function is used to periodically broadcast (without
interrogation) information about the aircraft that includes aircraft identification, position, altitude, velocity
and other aircraft status information.
• The traffic display shows the relative position of ADS-B or standard traffic using text, shapes, and
colors. ADS-B also provides similar information on ADS-B equipped ground vehicles.
• The effective surveillance range is 60 nmi. The passive-mode surveillance range is 160 nmi and
maintains report messages for a minimum of 200 1090ES ADS-B participants and 300 UAT ADS-B
participants simultaneously. To reduce display clutter a set number of other aircraft of the highest
priority other aircraft are displayed at a time. See Figure 1-2 for an example of own aircraft traffic
(UAT, 1090ES, TIS-B, and TAS).
• The Lynx NGT-9000 is equipped with a dual-link receiver. ADS-R service is unnecessary to provide
a complete picture of traffic in the area.
1.2.3 ADS-R System Overview
The Automatic Dependent Surveillance – Re-broadcast (ADS-R) is a ground based broadcast service that
repeats ADS-B messages from one link (1090ES or UAT) to the other link for aircraft with ADS-B In.
• ADS-R transmissions are updated at least every 2 seconds on the surface, 5 seconds in the terminal
area, and 10 seconds in the en-route airspace.
• An aircraft on the ground receiving ADS-R is provided both ground aircraft and vehicles as well as
airborne other aircraft within 5nm and 2,000 ft above ground level of the airport reference point.
• Other aircraft are provided by the ground station if within a 15 nm horizontal range and +/-5,000 ft
of altitude of the receiving aircraft. ADS-B equipped ground aircraft and vehicles are not displayed
to airborne aircraft. See Figure 1-2 for an example of own aircraft traffic (UAT, 1090ES, TIS-B, and
TAS).
1.2.4 TIS-B System Overview
Traffic Information Service Broadcast (TIS-B) is a ground based broadcast service that provides
secondary surveillance radar (SSR) derived traffic data (aircraft not equipped with ADS-B Out capability)
to ADS-B In equipped aircraft.
• The actual availability of services depends upon the availability of ground-based radar to support
TIS-B source data.
• Receiving aircraft must be in both radar coverage and ground based transceiver (GBT) coverage in a
given area to receive TIS-B service in that area. When ownship is above 24,000 ft, the ground station
will no longer provide TIS-B service. To reduce display clutter, the TIS-B service provides traffic
information on other aircraft within 15 nmi and +/- 3500 ft of ownship.
• Other aircraft are provided by the ground station if within a 15nm horizontal range and +/-3,500 ft of
altitude of the receiving aircraft. ADS-B equipped ground aircraft and vehicles are not displayed to
airborne aircraft. See Figure 1-2 for an example of own aircraft traffic (UAT, 1090ES, TIS-B, and
TAS).
