supports: The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union. A two-way radio is a radio that can do both transmit and receive a signal (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies, handie-talkies, or just hand-helds. Guildford 
  is a large town in Surrey, England, located southwest of central London on the A3 trunk road midway between the capital and Portsmouth. It is the seat of the borough of Guildford. Battersea Park is a 200 acre (83-hectare) green space at Battersea in the London Borough of Wandsworth in London. It is situated on the south bank of the River Thames opposite Chelsea, and was opened in 1858. Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio "wireless technology" include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary). Following Jupiter's satellite Io, the Moon is second-densest satellite among those whose densities are known.  England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet about a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating path around a body, although it may occasionally be used for a non recurring trajectory or a path around a point in space. To a close approximation, planets and satellites follow elliptical orbits, with the central mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. Commercial broadcasting (also called "private broadcasting") is the broadcasting of television programs and radio programming by privately owned corporate media, as opposed to state sponsorship. It was the United States first model of radio (and later television) during the 1920s, in contrast with the public television model in Europe during the 1930s, 1940s and 1950s which prevailed worldwide (except in the United States) until the 1980s. The University of Surrey is a public research university located within the county town of Guildford, Surrey, in the South East of England, United Kingdom. The university specialises in science, engineering, medicine and business. It received its charter on 9 September 1966, and was previously situated near Battersea Park in south-west London. The institution was known as "Battersea College of Technology" before gaining university status. Its roots, however, go back to the "Battersea Polytechnic Institute", founded in 1891 to provide further and higher education for London's poorer inhabitants. In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon. Surrey Satellite Technology Ltd , or SSTL , is a spin - off company of the University of Surrey , now majority - owned by EADS Astrium , that builds and operates small satellites . Its satellites began as amateur radio satellites known by the UoSAT ( University of Surrey SATELLITE ) name or by an OSCAR ( Orbital Satellite Carrying Amateur Radio ) designation . SSTL cooperates with the University 's Surrey Space Centre , which does research into satellite and space topics . SSTL moved into remote sensing services with the launch of the Disaster Monitoring Constellation ( DMC ) in 2002 and an associated child company , DMC International Imaging . SSTL also adopted the Internet Protocol for the DMC satellites it builds and operates , migrating from use of the AX.25 protocol popular in amateur radio . The CLEO Cisco router in Low Earth Orbit , on board the UK - DMC satellite along with a network of payloads , takes advantage of this adoption of the Internet Protocol . SSTL is also developing a new Geostationary Minisatellite Platform - Transfer orbit variant ( GMP - T ) aimed at the telecommunications market under the brand name SSTL - 900 . The University sold a 10 % share of SSTL to SpaceX in January 2005 . It then agreed to sell its majority share ( roughly 80 % of the capital ) to EADS Astrium in April 2008 . In August 2008 SSTL opened a US subsidiary . SSTL was awarded the Queen 's Award for Technological Achievement in 1998 , and the Queen 's Awards for Enterprise in 2005 . In 2006 SSTL won the Times Higher Education Supplement award for outstanding contribution to innovation and technology . In 2009 SSTL ranked 89 out of the 997 companies that took part in the Sunday Times Top 100 companies to work for . Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). Non-commercial (also spelled noncommercial) refers to an activity or entity that does not, in some sense, involve commerce, at least relative to similar activities that do have a commercial objective or emphasis. For example, advertising-free community radio stations are typically nonprofit organizations staffed by individuals volunteering their efforts to air a wide variety of radio programming, and do not run explicit radio advertisements, included in the United States specific grouping of "non-commercial educational" (NCE) public radio stations. Some Creative Commons licenses include a "non-commercial" option, which has been controversial in definition. Surrey is a county in the south east of England and also one of the home counties bordering Greater London.
