FLORIDA Airspace monitoring and management system
The FLORIDA Airspace Monitoring And Management System was an airspace monitoring and management system of the Swiss Air Force. It was built by Hughes Aircraft Company. It is located in Fullerton, California. History. The system was put into operation in about 1970, replacing the previous SRF Airspace monitoring and management system. With the FLORIDA manufacturer continuous 24-hour/365-day air surveillance was possible. In contrast to the SRF system, the FLORIDA system was already partially automated; it could identify radar data mostly by itself, and was able to calculate interception lines to a specific  radar track. The construction work, especially at Mount Pilatus, were widely visible to tourists. The system's radar antennas enhance the prediction of meteorological conditions (strong winds and lightning) and military attacks. The system by 2001 reached its end of its life. Requirements after 9/11 increased and the system's capacity of around 400 simultaneous objects could not keep up with increasing air traffic. The FLORIDA system was replaced in 2003 by FLORAKO. Technology. The FLORIDA system included three main components: Radar antennas. The four, elevated rotating radar antennas each consisted of a primary radar, and a secondary radar mounted  over the primary radar. They could be fully retracted into the mountain peak which was automatically closed with a massive door. The sites were equipped with AAA in rotatable domes for self-defense. Operational centers. Several wartime operational centers were located in mountain caverns. The operations center for peacetime use was sited at Dübendorf, adjacent to the surveillance squadron building. It is now used by the civilian Skyguide as a test center. The consoles were equipped with a trackball and allowed to edit each radar track quickly, when the system could not identify it. Each console had several displays showing  the best interception path (the path was shown in several numbers who stood for height, speed..) for the allocated intercept aircraft flying under the control of the tactical fighter controller (TFC) on this console. The TFC transmit by radio to the Aircraft by using the Bambini-Code (used in World War II by the Swiss Air Force-developed tactical code). Each operations center was equipped with a large status board which indicated the most important information of all the military airfields. Computing center. The computer center consists primarily of the computing system with the corresponding peripheral devices (magnet tape, printer , punch cards and paper tape) and interface devices (interfaces) for communication with the local (on-screen consoles, status board, etc.) and external subsystems (redundant computing centers, radar stations, Bl-64 positions, direction finders, eg.). The computer can process data from up to 400 aircraft simultaneously. Gallery. A FLORIDA radar antenna, statusboard, 2 consoles and a complete computer center are today in the Flieger-Flab-Museum at Dübendorf.
