TECHNOLOGY
Air traffic controllers use the state-of-the-art technology of DFS. Highly qualified engineers continuously develop new air traffic control systems which are tailored to meet the demands of the air traffic controllers. Additionally, DFS operates instrument landing systems at the international airports in Germany as well as radar and navigation facilities. These radar facilities are used to monitor the entire German airspace.
There are two basic types of radar: primary radar and secondary radar. Primary radar antennas transmit electromagnetic pulses which are reflected by the aircraft and returned to the antenna. In this way, it is possible to determine the position of each aircraft in airspace. However, this does not provide controllers with any information about the identity of the aircraft.
The secondary radar antenna which is mounted above the primary radar antenna also transmits electromagnetic signals. In contrast to the primary radar, these signals are not reflected but received by an antenna on board the aircraft. They activate a radar response which is returned to the secondary radar antenna. This signal, which consists of a four-digit number, informs the controller of the identity of the aircraft. The data appear on the controller's radar screen. Only after receiving this information can the controller identify the aircraft and assign a flight level and heading to the pilot.
