Disaster Monitoring Constellation
The Disaster Monitoring Constellation for International Imaging (DMCii) or just Disaster Monitoring Constellation (DMC) consists of a number of remote sensing satellites constructed by Surrey Satellite Technology Ltd (SSTL) and operated for the Algerian, Nigerian, Turkish, British and Chinese governments by DMC International Imaging. The DMC provides emergency Earth imaging for disaster relief under the International Charter on Space and Major Disasters, International Charter for Space and Major Disasters, which the DMC formally joined in November 2005. Other DMC Earth imagery is used for a variety of civil applications by a variety of governments. Spare available imaging capacity is sold under contract. The DMC provides far larger areas of imagery than, but at comparable resolution to, established government imaging satellites such as Landsat. DMC imagery was deliberately designed to be comparable to Landsat imagery, in order to leverage the expertise and software of the large esta ...

Remote Sensing
Remote sensing is the acquisition of information about an physical object, object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geophysics, geography, land surveying and most Earth science disciplines (e.g. exploration geophysics, hydrology, ecology, meteorology, oceanography, glaciology, geology). It also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term ''remote sensing'' generally refers to the use of satellite- or airborne-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on wave propagation, propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (when a signal is emitted b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Imaging Satellites
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers, and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. Earth has a dynamic atmosphere, which sustains Earth's ...

Satellites Orbiting Earth
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. 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 are small CubeSats. Similar satellites can work together as groups, forming constellations. Becau ...

Satellite Internet Access
Satellite Internet access is Internet access provided through communication satellites; if it can sustain high-speed Internet, high speeds, it is termed satellite broadband. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using the to achieve downstream data speeds up to 506 Data-rate units#Megabit per second, Mbit/s. In addition, new satellite internet constellations are being developed in Low Earth orbit, low-earth orbit to enable Network delay, low-latency internet access from space. History Following the launch of the first satellite, Sputnik 1, by the Soviet Union in October 1957, the US successfully launched the Explorer 1 satellite in 1958. The first commercial communications satellite was Telstar, Telstar 1, built by Bell Labs and launched in July 1962. The idea of a geosynchronous satellite—one that could orbit the Earth ...

University Of Surrey
The University of Surrey is a public research university in Guildford, Surrey, England. The university received its Royal Charter, royal charter in 1966, along with a Plate glass university, number of other institutions following recommendations in the Robbins Report. The institution was previously known as Battersea College of Technology and was located in Battersea Park, London. Its roots however, go back to Battersea Polytechnic Institute, founded in 1891 to provide Vocational education, further and higher education in London, including its poorer inhabitants. The university is a member of the Association of MBAs and is one of four universities in the University Global Partnership Network. It is also part of the SETsquared partnership along with the University of Bath, the University of Bristol, the University of Southampton, and the University of Exeter. The university's main campus is on Stag Hill, University of Surrey, Stag Hill, close to the centre of Guildford and adjacen ...

Deimos-1
Deimos-1 is a Spanish Earth imaging satellite which is operated by Deimos Imaging who commercializes its imagery directly but also has distribution agreements with other entities like Astrium GEO and DMC International Imaging. History It was constructed by Surrey Satellite Technology for Elecnor Deimos, representing the first Spanish Earth observation satellite and the first private one in Europe. It is based on the SSTL-100 satellite bus. Deimos-1 was launched into a Sun-synchronous low Earth orbit. The launch was conducted by ISC Kosmotras, who used a Dnepr carrier rocket, with DubaiSat-1 as the primary payload. Deimos-1, along with the UK-DMC 2, Nanosat 1B, AprizeSat-3 and AprizeSat-4 satellites, were launched as secondary payloads. The rocket was launched at 18:46 GMT on 29 July 2009, from Site 109/95 at the Baikonur Cosmodrome in Kazakhstan. The satellite was purchased from Elecnor Deimos by Urthecast in 2015, together with Deimos-2 and Deimos Imaging, the division ...

UK-DMC
UK-DMC or UK-DMC 1, also known as BNSCSAT-1, was a British satellite that formed part of the Disaster Monitoring Constellation (DMC). It was built by Surrey Satellite Technology, who operated it via DMC International Imaging on behalf of the British National Space Centre and later the UK Space Agency. It was launched alongside other DMC satellites on a Kosmos-3M, Kosmos-3M rocket from Plesetsk on 27 September 2003, and was retired from service in November 2011.
