ADS-B coverage

When operating outside of radar coverage, ADS-B derived ATS surveillance services will be provided to operators of authorised aircraft whilst within the coverage volume of commissioned ADS-B ground stations.

ADS-B ground stations are line-of-sight facilities. The ability for a ground station to received ADS-B data from an aircraft depends on altitude, distance from the site and obstructing terrain. Coverage will exist near the surface within 20 nautical miles of the ground station. High level coverage can exceed 250 nautical miles.

Note: In airspace where ADS-B coverage overlaps radar coverage, the radar derived aircraft position will be displayed to ATC.

End state ADS-B coverage at various flight levels can be viewed below:

ADS-B End State Coverage at 5,000 feet

ADS-B End State Coverage at 10,000 feet

ADS-B End State Coverage at 20,000 feet

ADS-B End State Coverage at 30,000 feet
