LGR-1 Radar
The LGR-1 (Lightweight Ground Radar 1) was used by Swiss Air Force from 1948 until 1955 for positioning the planned radar air surveillance system. It is now in the Flieger-Flab-Museum at Dübendorf. History This radar of the first generation of mobile radar systems in World War II was in the Allied invasion of Normandy in use. In Switzerland, the system was never used in the tactical way. It was used for determining the locations of the first Swiss airspace control system the SRF Airspace monitoring and management system. The LGR-1 radar was tested at various locations, including at the military airfield Dübendorf, at the Bütschelegg above Bern-Belp, at the Weisfluhgipfel ( Weissfluhjoch) and at the Creux du Van. As weatherprotection a wooden hut was built around the LGR-1. The transportable in 10 loads lightweight radar LGR-1 was developed during the Second World War by Bell Labs and Western Electric and built by Bendix Corporation in large numbers .

Radar WW2
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, Marine radar, ships, spacecraft, guided missiles, motor vehicles, Weather radar, weather formations, and terrain-following radar, terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio spectrum, radio or microwaves domain, a transmitting antenna (radio), antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a radio receiver, receiver and Data processing system, processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the ca ...

Swiss Air Force
The Swiss Air Force (german: Schweizer Luftwaffe; french: Forces aériennes suisses; it, Forze aeree svizzere; rm, Aviatica militara svizra) is the air component of the Swiss Armed Forces, established on 31 July 1914 as a part of the army and in October 1936 as an independent service. In peacetime, Dübendorf is the operational air force headquarters. The Swiss Air Force operates from several fixed bases (see current status) but its personnel are also trained to carry out air operations from temporary highway airstrips. In case of crisis or war, several stretches of road are specially prepared for this option. History Early years The first military aviation in Switzerland took the form of balloon transport, pioneered by Swiss balloonist Eduard Spelterini, but by 1914 there was still little official support for an air corps. The outbreak of World War I changed opinions drastically and cavalry officer Theodor Real was charged with forming a flying corps. He commandeered th ...

Flieger-Flab-Museum
The Flieger Flab Museum (English: Swiss Air Force Museum) is located in the Canton of Zurich in Dübendorf on the grounds of Dübendorf Air Base. In the museum, 40 airplanes and helicopters are displayed, with the collection divided into distinct eras: pioneers and World War I, the 1930s, World War II and the postwar period, the beginning of the jet age, the development of jet fighters, the Cold War, and arms reduction. History The collection was founded in 1972 by the Office for Military Airfields and dedicated to the history of Swiss military aviation and air defense. In 1972–1978, the collection was turned over to the state by the Swiss Federal Office for military airfields. In 1978, for the first time, the public were able to contribute to the collection, which grew steadily over the next few years. Finally, in 1979, the Friends of the Museum of the Swiss air force (VFMF) was formed, initiated by Hans Giger, the Director of the Federal Office for military airfields. D ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRF Airspace Monitoring And Management System
The SFR Airspace monitoring and management system was the first Airspace monitoring and management system of the Swiss Air Force. History After the second world war it became apparent that the rapid development of air defense of Switzerland without a comprehensive air surveillance was unrealistic. However, Switzerland lacked knowledge of such systems and the victorious Allies of World War II restricted both the sharing of knowledge and the sale of new radar equipment. Only the LGR-1 Radar was available. It was used to find suitable locations for the radar antennas of the SFR system. The core of the SFR system was the French ER-200 early warning and guidance radar from the Société Française Radioélectrique. The system was ordered on 31 January 1952, in a larger number of radar systems, radar components from which were compiled by its own architecture. From 1955 to 1966, a school complex in Dübendorf (the ''Radar Doerfli'' ("Radar village") on the training site Dürrbach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Creux Du Van
The Creux du Van is a natural rocky cirque approximately 1,400 metres wide and 150 metres deep, on the north side of Le Soliat, in the Val de Travers district in the Swiss canton of Neuchâtel. A very well known, amphitheatre-shaped natural attraction, it is at the heart of a nature reservation area of 15.5 km2. Geology The rocky arc of Creux du Van was created in three phases: Phase 1: A glacier covered the area of today's Val de Travers around 140,000 years ago ( Würm Ice Age). The stream of meltwater eroded material, making a V-shaped valley. Phase 2: During subsequent ice ages, other glaciers were created and hollowed out the valley. In warmer periods, the material was eroded by meltwater. Phase 3: After the removal of rocks from the fault, erosion of a stronger layer from a different age was much slower. See cirque for a description of the process forming features like this. The ground beneath the Creux du Van remains permanently frozen to this day ( ...

Target Allocation Radar TPS-1E
The Target allocation radar TPS-1E (German:Zielzuweisungsradar TPS-1E (ZZR)) is an omnidirectional pulse radar device. It was used from 1958 until 1989 by the Swiss Air Force. It was also used by German army (''Heer'') air defence reconnaissance platoons up until the early 1990s. History TPS-1E was ordered in the late 1950s for the heavy antiaircraft units. Target data were transmitted by telephone or radio to anti-aircraft artillery batteries. In the radar equipped batteries with the Fire control radar Mark VII, the Parallax computer Meta converted the data to local coordinates. In the remaining heavy antiaircraft radar batteries, data were used in manual targeting. In the middle of 1963 the ZZR was used together with the new Air Defence Operations Center 63 for the same task. After the introduction of fire control unit 75, Skyguard ZZR was incorporated in the new mobile radar units. It was used until the introduction of the TAFLIR systems in 1989.

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 coul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
