Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites. These measurements can be used to locate weather fronts, monitor the El Niño-Southern Oscillation, determine the strength of tropical cyclones, study urban heat islands and monitor the global climate. Wildfires, volcanos, and industrial hot spots can also be found via thermal imaging from weather satellites.
Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. It is named after Phobos, the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.
The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics.
Imagery intelligence (IMINT), pronounced as either as Im-Int or I-Mint, is an intelligence gathering discipline wherein imagery is analyzed to identify information of intelligence value. Imagery used for defense intelligence purposes is generally collected via satellite imagery or aerial photography.
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra satellite, launched by NASA in 1999; and one on board the Aqua satellite, launched in 2002. MODIS has now been replaced by the VIIRS, which first launched in 2011 aboard the Suomi NPP satellite.
BYEMAN codenamed GAMBIT, the KH-7 was a reconnaissance satellite used by the United States from July 1963 to June 1967. Like the older CORONA system, it acquired imagery intelligence by taking photographs and returning the undeveloped film to earth. It achieved a typical ground-resolution of 0.61 m to 0.91 m. Though most of the imagery from the KH-7 satellites was declassified in 2002, details of the satellite program remained classified until 2011.
Satellite images are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps.
Surrey Satellite Technology Ltd, or SSTL, is a company involved in the manufacture and operation of small satellites. A spin-off company of the University of Surrey, it is presently wholly owned by Airbus Defence and Space.
RapidEye AG was a German geospatial information provider focused on assisting in management decision-making through services based on their own Earth-observation imagery. The company operated a five-satellite constellation producing 5-meter resolution imagery that was designed and implemented by MacDonald Dettwiler of Richmond, Canada.
Commercial use of space is the provision of goods or services of commercial value by using equipment sent into Earth orbit or outer space. This phenomenon – aka Space Economy – is accelerating cross-sector innovation processes combining the most advanced space and digital technologies to develop a broad portfolio of space-based services. The use of space technologies and of the data they collect, combined with the most advanced enabling digital technologies is generating a multitude of business opportunities that include the development of new products and services all the way to the creation of new business models, and the reconfiguration of value networks and relationships between companies. If well leveraged such technology and business opportunities can contribute to the creation of tangible and intangible value, through new forms and sources of revenue, operating efficiency and the start of new projects leading to multidimensional positive impact. Examples of the commercial use of space include satellite navigation, satellite television and commercial satellite imagery. Operators of such services typically contract the manufacturing of satellites and their launch to private or public companies, which form an integral part of the space economy. Some commercial ventures have long-term plans to exploit natural resources originating outside Earth, for example asteroid mining. Space tourism, currently an exceptional activity, could also be an area of future growth, as new businesses strive to reduce the costs and risks of human spaceflight.
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 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.
GeoEye Inc. was an American commercial satellite imagery company based in Herndon, Virginia. GeoEye was merged into the DigitalGlobe corporation on January 29, 2013.
Hard X-ray Modulation Telescope (HXMT) also known as Insight is a Chinese X-ray space observatory, launched on June 15, 2017 to observe black holes, neutron stars, active galactic nuclei and other phenomena based on their X-ray and gamma-ray emissions. It is based on the JianBing 3 imagery reconnaissance satellite series platform.
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.
Urthecast was a Canadian company that specialized in satellite imaging, data services and geo-analytics. The company operated two cameras on the International Space Station (ISS) and two satellites in low Earth orbit. Urthecast also planned to launch two satellite constellations, OptiSAR and UrtheDaily, to provide global coverage and high-resolution imagery of the Earth. However, the company faced financial difficulties and filed for creditor protection in 2020. A new start-up, EarthDaily Analytics, emerged from Urthecast’s insolvency in 2021.
The Mohammed bin Rashid Space Centre is a Dubai government organisation working on the UAE space programme, which includes various space satellite projects, the Emirates Mars Mission, the Emirates Lunar Mission, and the UAE astronaut programme. The centre actively works to promote space science and research in the region. The centre encompasses the Emirates Institution for Advanced Science and Technology (EIAST).
Deimos-2 is a Spanish remote sensing Earth observation satellite built for Elecnor Deimos under an agreement with Satrec Initiative, a satellite manufacturing company in South Korea.
Elecnor Deimos is Elecnor's technological arm. The group specialises in the design, engineering and development of solutions and systems integration in the aerospace, defense, satellite systems, remote sensing, information systems and telecommunications network sectors.
Satrec Initiative Co., Ltd. or Satrec i or SI is a South Korean satellite manufacturing company headquartered in Daejeon, South Korea The company was founded in 1999 by the engineers who developed the first Korean satellite (KITSAT-1) at KAIST Satellite Technology Research Center (SaTRec). The company designs and builds Earth observation satellites called SpaceEye-series, and it provides various space components, including high resolution electro-optical payloads and star-trackers.
