Skewjack
Skewjack is the name of a plot of land in west Cornwall, England, United Kingdom. It is situated about 1.5 miles (2 km) east of Land's End on the B3315 road. It was the site of RAF Sennen, and is now the site of a Fibre-optic Link Around the Globe building. RAF Sennen Skewjack became well known in the Second World War when a Royal Air Force station known as RAF Sennen was set up in 1942 between Skewjack Farm and nearby Trebehor Farm, about half-a-mile (1 km) to the south east. The RAF radar site was actually about 1 mile (1.5 km) from Sennen Churchtown village or about 2 miles (3 km) from Sennen Cove and at a good location for radio line-of-sight ( LOS) towards the Atlantic Ocean. Several masts were erected, some over 300 feet (100 m) high, in nearby fields to support radar antennas as part of an early warning radar station. Code-named "Chain Home Low", the equipment was very advanced for the early days of radar, being able to detect ships and appr ...

Fibre-optic Link Around The Globe
Fibre-optic Link Around the Globe (FLAG) is a fibre optic mostly-submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. The system runs from the eastern coast of North America to Japan. Its Europe-Asia segment was the fourth longest cable in the world in 2008. The Europe-Asia segment was laid by Cable & Wireless Marine in the mid-1990s, and was the subject of an article in ''Wired'' magazine in December 1996 by Neal Stephenson. Description The FLAG cable system was first placed into commercial service in late 1997. FLAG offered a speed of 10 Gbit/s, and uses synchronous digital hierarchy technology. It carries over 120,000 voice channels via of mostly undersea cable. FLAG uses erbium-doped fibre amplifiers, and was jointly supplied by AT&T Submarine Systems and KDD-Submarine Cable Systems.

GCHQ Bude
GCHQ Bude, also known as GCHQ Composite Signals Organisation Station Morwenstow, abbreviated to GCHQ CSO Morwenstow, is a UK Government satellite ground station and eavesdropping centre located on the north Cornwall coast at Cleave Camp, between the small villages of Morwenstow and Coombe. It is operated by the British signals intelligence service, officially known as the Government Communications Headquarters, commonly abbreviated GCHQ. It is located on part of the site of the former World War II airfield, RAF Cleave. History The site of GCHQ Bude is in Morwenstow, the northernmost parish of Cornwall. During World War II, the location was developed for and used by the Royal Air Force (RAF). RAF Cleave was conceived as housing target and target support aircraft for firing ranges along the north Cornwall coast, and land was acquired from Cleave Manor. In 1939, it became home to two flights of (1AAC). In 1943, No. 639 Squadron was established on the site for the rema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sennen Cove
Sennen Cove ( kw, Porthsenen) () is a small coastal village in the parish of Sennen in Cornwall, England, United Kingdom. According to the Penwith District Council, the population of this settlement was estimated at 180 persons in 2000. The South West Coast Path passes through Sennen Cove. Geography The village of Sennen Cove overlooks the southern end of Whitesand Bay. There is not a cove in the usual geological sense. The village (as distinct from Sennen Churchtown), is on a spur road which joins the A30 trunk road about two miles (3 km) from Land's End. Thus it is the first village from Land's End along the north coast. The road descends gently for about 300 yards and then steeply for another 300 yards to the village which lies above the beach. The beach extends further north along Whitesand Bay. There are a few dozen houses built primarily of granite and some of concrete, arranged mainly in terraces, typical of many of the villages in Cornwall. Several submarine t ...

GEE (navigation)
Gee, sometimes written GEE, was a radio navigation system used by the Royal Air Force during World War II. It measured the time delay between two radio signals to produce a fix, with accuracy on the order of a few hundred metres at ranges up to about . It was the first hyperbolic navigation system to be used operationally, entering service with RAF Bomber Command in 1942. Gee was devised by Robert Dippy as a short-range blind landing system to improve safety during night operations. During development by the Telecommunications Research Establishment (TRE) at Swanage, the range was found to be far better than expected. It then developed into a long-range, general navigation system. For large, fixed targets, such as the cities that were attacked at night, Gee offered enough accuracy to be used as an aiming reference without the need to use a bombsight or other external references. Jamming reduced its usefulness as a bombing aid, but it remained in use as a navigational aid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campaign To Protect Rural England
CPRE, The Countryside Charity, formerly known by names such as the ''Council for the Preservation of Rural England'' and the ''Council for the Protection of Rural England'', is a charity in England with over 40,000 members and supporters. Formed in 1926 by Patrick Abercrombie to limit urban sprawl and ribbon development, the CPRE claims to be one of the longest running environmental groups in the UK. CPRE campaigns for a "sustainable future" for the English countryside. They state it is "a vital but undervalued environmental, economic and social asset to the nation." They aim to "highlight threats and promote positive solutions." They campaign using their own research to lobby the public and all levels of government. History CPRE was formed following the publication of “The Preservation of Rural England” by Sir Patrick Abercrombie in 1926. Abercrombie became its Honorary Secretary. The inaugural meeting was held in December 1926 at the London offices of the Royal Institute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as code ...

Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by pr ...

Mobile Telephone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as feat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
