Automatic Dependent Surveillance – Re-broadcast (ADS-R)
ADS-R is a ground based broadcast service that repeats ADS-B
messages from one link (1090 MHz or 978 MHz) to the other link for
aircraft with ADS-B In.
• ADS-R does NOT relieve the pilot of responsibility to “see-and-
avoid” other aircraft.
• No avoidance maneuvers are provided for, nor authorized, as a
direct result of a ADS-R other aircraft being displayed in the cockpit.
Avoidance maneuvers must be based on visually acquiring the
target.
• The actual availability of services depends upon both the availability
of a ground station to support ADS-R source data and aircraft being
within range of the ground station.
• 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.
• 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.
• 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.
• Receiving aircraft must be in both ATC radar coverage and ground
based transceiver (GBT) coverage in a given area to receive
ADS-R service in that area. ADS-R range is larger than the TIS-B
range of 24,000 ft above station.
