ADS-B and Functions for Flight Inspection
Automatic Dependent Surveillance Broadcast (ADS-B) provides functions for surveillance of aircraft and ground vehicles with high accuracy. The capability for ADS-B output will become mandatory for many aircraft very soon. A network of ADS-B ground stations is currently under installation. The requirements for flight inspection of ADS-B are not yet settled.
This paper highlights the differences of the ADS-B standards (RTCA-DO260, DO260A and DO260B) and introduces the most significant ADS-B performance parameter in the DF17 1090MHz extended squitter messages. Theoretically, ADS-B seems to be ideal for surveillance, but on the other hand a lot of problems can be observed in reality when analyzing ADS-B data transmitted by various aircraft. These typical problems during the use of ADS-B for air traffic surveillance are explained in detail. Based on these case studies desirable functions for the flight inspection of ADS-B ground stations are derived.
