Automatic subscriber monitoring (ADS-B)
A lot of technology is used to improve airspace surveillance. This includes the ADS-B, which performs many tasks. This is used for both manned and unmanned air traffic.
Automatic Dependent Surveillance - Broadcast is used so that air traffic control can obtain a clearer picture of the airspace and use this information to increase safety. The combination of satellite navigation systems, the systems on board the aircraft itself and the systems on the ground creates very precise information and data. This in turn is necessary for air traffic control to communicate with the aircraft in the airspace.
This is also the case over the greater Oldenburg-Hatten airfield (EDWH) area. For Hatten-UAS, manned and unmanned systems are identified and recorded with the help of ADS-B. The recorded data will in future be processed by b.r.m. IT & Aerospace, as the future USSP. ADS-L, the asymmetric digital subscriber line, is also currently being implemented for the Hatten-UAS drone test center. This was published by EASA in December 2022 as the ADS-L standard.

How does the ADS-B work?
The aircraft usually determine their position using GPS and transmit this, together with other basic data, to other aircraft and ground stations. Data is transmitted between aircraft via air-to-air links. Networking between the aircraft and the ground station, such as radars or air traffic control, is called an air-to-ground link. Air traffic control on the ground processes the data from the ADS-B output and forwards it back to the aircraft via ADS-B input. This gives the pilot the same overview as air traffic control. Automatic Dependent Surveillance - Broadcast is therefore significantly better than the information from radars.
For this reason, Automatic Dependent Surveillance - Broadcast is also an important part of the Due Regard Radar, for example, which is the key component for a Detect and Avoid architecture. ADS-B and the Traffic Collision Avoidance System (TCAS) are used to detect and track cooperative transponder-equipped aircraft.
