GeoEye-1
''GeoEye-1'' is a high-resolution Earth observation satellite owned by DigitalGlobe, launched in September 2008. The satellite was acquired in the 2013 purchase of GeoEye. History On 1 December 2004, General Dynamics C4 Systems announced it had been awarded a contract worth approximately to build the ''OrbView-5'' satellite. Its sensor is designed by the ITT Exelis. The satellite, now known as ''GeoEye-1'', was originally scheduled for launch in April 2008 but lost its 30-day launch slot to a U.S. government mission which had itself been delayed. It was rescheduled for launch 22 August 2008 from Vandenberg Air Force Base aboard a Delta II launch vehicle. The launch was postponed to 4 September 2008, due to unavailability of the Big Crow telemetry-relay aircraft. It was delayed again to 6 September because Hurricane Hanna interfered with its launch crews. The launch took place successfully on 6 September 2008 at 18:50:57 UTC. The ''GeoEye-1'' satellite separated succe ...

DigitalGlobe
DigitalGlobe is an American commercial vendor of space imagery and geospatial content, and operator of civilian remote sensing spacecraft. The company went public on the New York Stock Exchange on 14 May 2009, selling 14.7 million shares at US$19.00 each to raise US$279 million in capital. On 5 October 2017, Maxar Technologies completed its acquisition of DigitalGlobe. The company's "WorldView" satellites should not be confused with the unrelated WorldView company (a stratospheric balloon operator). Origins WorldView Imaging Corporation was founded in January 1992 in Oakland, California in anticipation of the 1992 Land Remote Sensing Policy Act (enacted in October 1992) which permitted private companies to enter the satellite imaging business. Its founder was Dr Walter Scott, who was joined by co-founder and CEO Doug Gerull in late 1992. In 1993, the company received the first high resolution commercial remote sensing satellite license issued under the 1992 Act. The company ...

WorldView-1
''WorldView-1'' (WV 1) is a commercial earth observation satellite owned by DigitalGlobe. WorldView-1 was launched on 18 September 2007, followed later by the ''WorldView-2'' in 2009. First imagery from ''WorldView-1'' was available in October 2007, prior to the six-year anniversary of the launch of ''QuickBird'', DigitalGlobe's previous satellite. ''WorldView-1'' was partially financed through an agreement with the National Geospatial-Intelligence Agency (NGA). Some of the imagery captured by ''WorldView-1'' for the NGA is not available to the general public. However, ''WorldView-1'' freed capacity on DigitalGlobe's ''QuickBird'' satellite to meet the growing commercial demand for multi-spectral geospatial imagery. Design Ball Aerospace built the ''WorldView-1'' satellite bus and camera using an off-axis camera design identical to ''Quickbird'', with the instrument's focal plane being supplied by ITT Exelis. The camera is a panchromatic imaging system featuring half-meter resol ...

Earth Observation Satellite
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others. The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation. The first occurrence of satellite remote sensing can be dated to the launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. Sputnik 1 sent back radio signals, which scientists used to study the ionosphere. The United States Army Ballistic Missile Agency launched the first American satellite, Explorer 1, for NASA’s Jet Propulsion Laboratory on January 31, 1958. The information sent back from its radiation detector led to the discovery of the Earth's ...

Multispectral
Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, i.e. infrared and ultra-violet. It can allow extraction of additional information the human eye fails to capture with its visible receptors for red, green and blue. It was originally developed for military target identification and reconnaissance. Early space-based imaging platforms incorporated multispectral imaging technology to map details of the Earth related to coastal boundaries, vegetation, and landforms. Multispectral imaging has also found use in document and painting analysis. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands. Hyperspectral imaging is a special case of spectral imaging where often hundreds of contiguous ...

Spacecraft Launched In 2008
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ...
