Automatic dependent surveillance-broadcast (ADS-B) is a technique which allows the tracking of aircraft in flight and on the surface. Enhancements of the functionality and interfaces are required to the ground surveillance system, in order to make it compliant with the new applications of ADS-B in radar airspace, ADS-B for airport surveillance and other emerging requirements, such as security.

This SESAR solution #110 "ADS-B surveillance of aircraft in flight and on the surface" consists of ADS-B ground station and surveillance data processing and distribution (SDPD) functionality. The solution also offers detection and mitigation techniques against deliberate spoofing of the ground system by outside agents. These techniques can also be used to cope with malfunctioning of avionics equipment. SESAR has contributed to the relevant standards, such as EUROCAE technical specifications, incorporating new functionalities developed for the ADS-B ground station, ASTERIX interface specifications as well as to the SDPD specifications.

This solution #110 is implemented in Germany, France and Hungary and planned in Austria, Estonia, Spain, Italy, Lithuania, Portugal and the Slovak Republic.
