Air Defence Research And Development Establishment
The Air Defence Research and Development Establishment (ADRDE) was a civilian research organization run by the War Office that primarily studied the development of radar for British Army use. It was formed in 1941 from the merger of the Air Defence Experimental Establishment in Christchurch, Dorset and the "Army Cell" that had previously worked on radar design within the Air Ministry's Telecommunications Research Establishment at Bawdsey Manor. The ADRDE existed under this name for only a short time; in May 1942 it moved to Malvern and was renamed the Radar Research and Development Establishment (RRDE). In March 1943, the Signals Research and Development Establishment (SRDE) took over the former ADRDE buildings in Christchurch. Years later, in 1976, the SRDE joined the RRDE in Malvern. While still known as ADRDE, the group was responsible for the ''ad hoc'' development of the SLC radar, as well as GL Mk. II radar and the start of the GL Mk. III radar Radar, Gun Laying, Mark II ...

War Office
The War Office was a department of the British Government responsible for the administration of the British Army between 1857 and 1964, when its functions were transferred to the new Ministry of Defence (MoD). This article contains text from this source, which is available under th Open Government Licence v3.0 © Crown copyright It was equivalent to the Admiralty, responsible for the Royal Navy (RN), and (much later) the Air Ministry, which oversaw the Royal Air Force (RAF). The name 'War Office' is also given to the former home of the department, located at the junction of Horse Guards Avenue and Whitehall in central London. The landmark building was sold on 1 March 2016 by HM Government for more than £350 million, on a 250 year lease for conversion into a luxury hotel and residential apartments. Prior to 1855, 'War Office' signified the office of the Secretary at War. In the 17th and 18th centuries, a number of independent offices and individuals were re ...

Radar Research And Development Establishment
The Radar Research and Development Establishment, RRDE for short, was a civilian research organization run by the United Kingdom's Ministry of Supply that primarily studied the development of radar for British Army use. The group traces its history to the Searchlight Experimental Establishment which moved to RAF Biggin Hill in 1924, and the "Army Cell" operating at Bawdsey Manor researching radar beside their Air Ministry counterparts. In 1941 the Army groups merged and moved to Christchurch, Dorset and were renamed the Air Defence Research and Development Establishment. In May 1942 the group moved again, this time to an inland location at Malvern, Worcestershire, and were once again renamed to become the RRDE. Their Air Ministry counterparts, who had also moved to the Dorset area and been renamed the Telecommunications Research Establishment (TRE), joined them in Malvern over the next few months. The RRDE retained their name until 1953 when they merged with the TRE to form the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Research Establishments Of The United Kingdom
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Telecommunications In The United Kingdom
Telecommunications in the United Kingdom have evolved from the early days of the telegraph to modern broadband and mobile phone networks with Internet services. History National Telephone Company (NTC) was a British telephone company from 1881 until 1911 which brought together smaller local companies in the early years of the telephone. Under the Telephone Transfer Act 1911 it was taken over by the General Post Office (GPO) in 1912. Until 1982, the main civil telecommunications system in the UK was a state monopoly known (since reorganisation in 1969) as Post Office Telecommunications. Broadcasting of radio and television was a duopoly of the BBC and Independent Broadcasting Authority (IBA): these two organisations controlled all broadcast services, and directly owned and operated the broadcast transmitter sites. Mobile phone and Internet services did not then exist. The civil telecoms monopoly ended when Mercury Communications arrived in 1983. The Post Office system evolved ...

SLC Radar
Searchlight Control, SLC for short but nicknamed "Elsie", was a British Army VHF-band radar system that provided aiming guidance to an attached searchlight. By combining a searchlight with a radar, the radar did not have to be particularly accurate, it only had to be good enough to get the searchlight beam on the target. Once the target was lit, normal optical instruments could be used to guide the associated anti-aircraft artillery. This allowed the radar to be much smaller, simpler and less expensive than a system with enough accuracy to directly aim the guns, like the large and complex GL Mk. II radar. In 1943 the system was officially designated Radar, AA, No. 2, although this name is rarely used. The sight of searchlights swinging about wildly during the Blitz led a group of British Army engineers to begin development of SLC in early 1940. It was built using the electronics from the 1.5 m wavelength ASV Mark I connected to new antennas and a unique lobe switching sys ...

Signals Research And Development Establishment
__NOTOC__ The Signals Research and Development Establishment (SRDE) was a British government military research establishment, based in Christchurch, Dorset from 1943 until it merged with the Royal Radar Establishment (RRE) in Malvern, Worcestershire to form the Royal Signals and Radar Establishment (RSRE) in 1976. Its focus was military communications (signals). History The establishment had its origins in the Royal Engineers Wireless Telegraphy Experimental Section founded at Aldershot in the very early part of the twentieth century. It moved to Woolwich, initially into the former Royal Dockyard (at that time a military stores depot) where it formed part of the Inspectorate of Royal Engineers Stores, before moving on to Woolwich Common. In 1914 it was operating out of a van at Woolwich, but in 1916 it settled into its own premises, becoming the Signals Experimental Establishment. The establishment was renamed SRDE at the start of the Second World War; it moved briefly to Horsham b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvern, Worcestershire
Malvern is a spa town and civil parish in Worcestershire, England. It lies at the foot of the Malvern Hills, a designated Area of Outstanding Natural Beauty. The centre of Malvern, Great Malvern, is a historic conservation area, which grew dramatically in Victorian times due to the natural mineral water springs in the vicinity, including Malvern Water. At the 2011 census it had a population of 29,626. It includes Great Malvern on the steep eastern flank of the Malvern Hills, as well as the former independent urban district of Malvern Link. Many of the major suburbs and settlements that comprise the town are separated by large tracts of open common land and fields, and together with smaller civil parishes adjoining the town's boundaries and the hills, the built up area is often referred to collectively as The Malverns. Archaeological evidence suggests that Bronze Age people had settled in the area around 1000 BC, although it is not known whether these settlements were permane ...

Radar
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, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and 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 cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Bawdsey Manor
Bawdsey Manor stands at a prominent position at the mouth of the River Deben close to the village of Bawdsey in Suffolk, England, about northeast of London. Built in 1886, it was enlarged in 1895 as the principal residence of Sir William Cuthbert Quilter. Requisitioned by the Devonshire Regiment during World War I and having been returned to the Quilter family after the war, it was purchased by the Air Ministry for £24,000 in 1936 to establish a new research station for developing the Chain Home RDF (radar) system. RAF Bawdsey was a base through the Cold War until the 1990s. The manor is now used by PGL for courses and children's holidays. There is a small museum in the radar transmitter block. History Quilter period: 1886 to 1936 Bawdsey Manor was built in 1886 and enlarged in 1895 by William Quilter who was an art collector, one of the founders of the National Telephone Company, and was Liberal/Liberal Unionist Member of Parliament for Sudbury. He established a steam- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
