As of December 2018 there are 320 known military or dual-use satellites in the sky, half of which are owned by the US, followed by Russia, China and India (13).[1]. Eight satellites took pictures on film roll, which were then parachuted back into the atmosphere, where a perfectly timed US military plane snatched it mid-air before it could be intercepted. In a 7 June 2016 article entitled, ”Spy satellites reveal early start to Antarctic ice shelf collapse,” Thomas Sumner reported: “Analyzing declassified images from spy satellites, researchers discovered that the downhill flow of ice on Antarctica’s Larsen B ice shelf was already accelerating as early as the 1960s and ’70s. Read below to see our go-to list of free satellite imagery sources. We map out and quantify the world’s complexities so that organizations can make more informed decisions.”, “By applying artificial intelligence to satellite, UAV, and other geospatial data sources, we seek to discover and quantify societal and economic trends on Earth that are indistinguishable to the human eye. The National Reconnaissance Office (NRO) is responsible for developing and operating space reconnaissance systems and conducting intelligence-related activities for US national security. Geospatial intelligence, or GEOINT, is the exploitation and analysis of imagery and geospatial information to describe, assess and visually depict physical features and geographically referenced activities on the Earth. NGA’s predecessor agencies, with comparable missions, were: The NGA’s web homepage, at the following link: https://www.nga.mil/Pages/Default.aspx, The NGA’s webpage for declassified satellite imagery is here: https://www.nga.mil/ProductsServices/Pages/Imagery.aspx, 2. There have also been a number of subsequent programs including Magnum and Trumpet,[7] but these remain classified and therefore many details remain speculative. The Soviet Union began the Almaz (Russian: Алмаз) program in the early 1960s. By Olivia Solon. Typically military satellites operate in the UHF, SHF (also known as X-band) or EHF (also known as Ka band) frequency bands. Example applications of declassified military reconnaissance satellite imagery. Some attempts were made to develop satellite based weapons but this work was halted in 1967 following the ratification of international treaties banning the deployment of weapons of mass destruction in orbit. Since 1972, Landsat satellites have continuously acquired low-to-moderate resolution digital images of the Earth’s land surface, providing long-term data about the status of natural resources and the environment. A military satellite is an artificial satellite used for a military purpose. 83, No. [20], Why Isro's Gsat-7A launch is important for the Indian Air Force, "Military Satellite Systems: A History — Part One", "Russian Satellite Maneuvers, Silence Worry Intelsat", "Why Did the Department of Defense Develop GPS? Squadron Leader KK Nair, "Space: The Frontiers of Modern Defence", This page was last edited on 31 December 2020, at 03:40. The UK government is pushing ahead with its plans for a cluster of military radar satellites, placing a design study with Airbus. Up until the 1960s, Aral Sea salinity was around 10 grams per liter, less than one-third the salinity of the ocean. In 1958, the United States initiated Project Defender to develop an anti-ICBM solution launched from satellites. Only military sources, however, have access to images captured at the satellite's maximum ground resolution of 0.41 meters; Commercial clients' images are re-sampled at a 0.5-meter resolution. NRO developed several generations of classified Keyhole (KH) military optical reconnaissance satellites that have been the primary sources of Earth imagery for the US Department of Defense (DoD) and intelligence agencies. After recovery, the film was processed and analyzed. This program involved placing space stations in Earth orbit as an alternative to satellites. [2] Within this program a number of sub-programs were developed including Corona. NASA has developed in recent years a platform, called Land, Atmosphere Near Real-time Capability for EOS (LANCE), to provide near real-time data to those needing data and use of platforms such as MODIS. USGS reports: “The Aral Sea once covered about 68,000 square kilometers, a little bigger than the U.S. state of West Virginia. Overview of US military optical reconnaissance satellite programs. Combining this information with terrestrial data, such as mobile and location-based data, unlocks new sources of intelligence.”, The Orbital Insight website is here: https://orbitalinsight.com/company/, 5. In the United States, research into satellite based weapons was initiated by President Dwight D. Eisenhower in the 1950s. [citation needed], In 2015, United States military space units, and commercial satellite operator Intelsat, became concerned about apparent reconnaissance test maneuvers by Russian Luch (or Olymp) satellite which was launched in September 2014, when it maneuvered between the Intelsat 7 and Intelsat 901 satellites which are located only half a degree from one another in geosynchronous orbit.[8]. The first launches were code named Discoverer. Fo… Free, browsable data. The advent of the US civilian Earth observation programs. [14] Full Operational Capability (FOC) was declared by Air Force Space Command (AFSPC) in April 1995, signifying full availability of the military's secure Precise Positioning Service (PPS).[14]. This set of photos, declassified in 2002, consists of photographs from the KH-7 GAMBIT surveillance system and KH-9 HEXAGON mapping program. Satellite Imagery Intelligence for Defence Operations. Experience Earth on any device See all Earth versions. It is not possible to identify the exact number of these that are military satellites partly due to secrecy and partly due to dual purpose missions such as GPS satellites that serve both civilian and military purposes. Declassified satellite imagery (e.g., Corona, Argon and Lanyard) used in early mapping programs may be obtained from the USGS EROS Data Center at 605-594-6151 or custserv@usgs.gov or from the National Archives at 301-837-1926 or carto@nara.gov. The latest changes are being observed through satellite imagery at Hotan in occupied East Turkestan, now Xinjiang, which is one of the People’s Liberation Army Air Force’s (PLAAF) major fighter airbases. Commercial Data In Use. Six spacecraft were launched between 1994 and 2003, of which five are operational, with the sixth lost in a launch failure. During the Cold War arms race, the nuclear threat was used to justify the cost of providing a more capable system. The treaty became effective on 10 October 1967 and, as of May 2013, 102 countries are parties to the treaty with a further 27 pending full ratification.[16][17]. In a 19 June 2019 paper “Acceleration of ice loss across the Himalayas over the past 40 years,” the authors, reported on the use of HEXAGON KH-9 mapping camera imagery to improve their understanding of trends affecting the Himalayan glaciers from 1975 to 2016: “Himalayan glaciers supply meltwater to densely populated catchments in South Asia, and regional observations of glacier change over multiple decades are needed to understand climate drivers and assess resulting impacts on glacier-fed rivers.

This set of photos, declassified in 2011, consists of more photographs from the KH-9 HEXAGON mapping program. Pinkmatter's FarEarth Global Observer presents a live view of Landsat imagery as it is downlinked by ground-stations around the world. The USGS explains: “The images were originally used for reconnaissance and to produce maps for U.S. intelligence agencies. The US Navy required precise navigation to enable submarines to get an accurate fix of their positions before they launched their SLBMs. These sites are often clearly visible on CORONA imagery, enabling researchers to map sites that have been lost and to discover many that have never before been documented. The table of contents to the Earthshots webpages is shown below and is at the following link: http:// https://earthshots.usgs.gov/earthshots/, For the Aral Sea region, the Earthshots photo sequences start with ARGON KH-5 photos taken in 1964. Not only can you download the latest, greatest satellite imagery… but it’s all FREE. Google Earth on web Now available on Chrome and coming soon to more browsers. The USGS explains: “The images were originally used for reconnaissance and to produce maps for U.S. intelligence agencies. The first military satellites were photographic reconnaissance missions. The data applications include science, environment studies, resources and disaster management, computer science. When lives are at stake, defence and security-related decisions require accurate, actionable intelligence and a detailed understanding of the situation on the ground. The original film is held by the National Archives and Records Administration (NARA). 1. All you need to know is where to find them. [19], Skynet 5 is the United Kingdom's most recent military communications satellite system. This program has been superseded by the Space-Based Infrared System (SBIRS). While such imagery access is relatively rapid, it still prevents individuals and organizations from accessing data that needs to be more immediate. 7, July 2017. About 18,000 black-and-white images and 230 color images are available. Three stations were launched between 1973 and 1976: Salyut 2, Salyut 3 and Salyut 5. Bing Maps. Work within an analyst team and as an individual imagery … Stratfor Military Analyst Sim Tack explains a series of satellite images that show the construction of a Russian air base in Syria. In 1976, NRO deployed its first electronic imaging optical reconnaissance satellite known as KENNEN KH-11 (renamed CRYSTAL in 1982), which eventually replaced the KH-9, and brought an end to reconnaissance satellite missions requiring film return. Communications satellites are used for military communications applications. Free satellite imagery download is available from GBLF via an FTP client. The declassified imagery is held by the following two organizations: The declassified military satellite imagery available in the EROS archive is summarized below: USGS EROS Archive – Declassified Satellite Imagery – 1 (1960 to 1972), USGS EROS Archive – Declassified Satellite Imagery – 2 (1963 to 1980), USGS EROS Archive – Declassified Satellite Imagery – 3 (1971 to 1984), More information on the declassified imagery resources is available from the USGS EROS Archive – Products Overview webpage at the following link (see heading “Declassified Data”): https://www.usgs.gov/centers/eros/science/usgs-eros-archive-products-overview?qt-science_center_objects=0#qt-science_center_objects, 4. Not all KH-9 satellite missions included a mapping camera. Duplicate film held in the USGS Earth Resources Observation and Science (EROS) Center archive is used to produce digital copies of the imagery for distribution to users. [12], In 1978, the first experimental Block-I GPS satellite was launched[13] and by December 1993, GPS achieved initial operational capability (IOC), indicating a full constellation (24 satellites) was available and providing the Standard Positioning Service (SPS). Protected systems offer more sophisticated security protection like antijam features and nuclear survivability, while narrowband systems are intended for basic communications services that do not require high bandwidth. This satellite offers military-grade imagery to the masses. KH-7 image resolution is 2 to 4 feet (0.6 to 1.2 meters). The KH-9 mapping camera was designed to support mapping requirements and exact positioning of geographical points. The first satellite navigation system, Transit, used by the United States Navy, was tested in 1960. NRO’s website is here: NRO’s early generations of Keyhole satellites were placed in low Earth orbits, acquired the desired photographic images on film during relatively short-duration missions, and then returned the film to Earth in small reentry capsules for airborne recovery. CORONA image resolution improved from 40 feet (12.2 meters) for the KH-1 to about 6 feet (1.8 meters) for the KH-4B. And remember – if you just want to look at satellite imagery without downloading the data, check out our list of 25 satellite maps. Following Salyut 5, the Soviet Ministry of Defence judged in 1978 that the time consumed by station maintenance outweighed the benefits relative to automatic reconnaissance satellites. Military Strategic and Tactical Relay, or Milstar, is a constellation of military satellites managed by the United States Air Force. There are four Skynet satellites in orbit, with the latest launch completed in December 2012. A military satellite is an artificial satellite used for a military purpose, often for gathering intelligence, as a communications satellite used for military purposes, or as a weapon. In the United States the first formal military satellite programs, Weapon System 117L, was developed in the mid 1950s. All military reconnaissance satellite imagery was highly classified until 1995, when some imagery from early defense reconnaissance satellite programs was declassified. Use imagery to analyse and report significant features and activity at military installations. The big question for a lot of people is: "What can they see?" [citation needed] Corona was followed by other programs including Canyon (seven launches between 1968 and 1977[4]), Aquacade[5] and Orion (stated by US Government sources to be extremely large[6]). The smaller the pixel size, the sharper the image. In 1992, an Environmental Task Force evaluated the application of early satellite data for environmental studies. [2] Satellites within the Corona program carried different code names. With imagery collected from the past two decades, along with so many different options available, we can offer high resolution imagery for nearly any place on Earth. In this case, data are available as quick as within 3 hours of when imagery was taken. They are deployed in geostationary orbit and provide wideband, narrowband and protected military communication systems. The first US military optical reconnaissance satellite program, code named CORONA, pioneered the development and refinement of the technologies, equipment and systems needed to deploy an operational orbital optical reconnaissance capability. 14 Aug 2014. The first generation of U.S. photo intelligence satellites collected more than 860,000 images of the Earth’s surface between 1960 and 1972. You can explore the Aral Sea Earthshots photo sequences at the following link: https://earthshots.usgs.gov/earthshots/node/91#ad-image-0-0. Below are three screenshots  of the USGS Earthshots pages showing the KH-5 images for the whole the Aral Sea, the North Aral Sea region and the South Aral Sea region. Credit: Arianespace. They are typically used to take overhead photos for military missions. The declassified imagery is an important supplement to other Earth imagery sources. A European satellite designed to collect Earth sciences data and distribute it freely to people around the world has the unintended consequence of detecting military radars. A first military satellite named Noor is launched into orbit by Iran's Revolutionary Guards Corps, in Semnan, Iran April 22, 2020. Use imagery to analyse and report on the status and activity of deployed military forces. Resolutions for the sensors in this section range between 0.3 meter (the highest commercially available) to 1 meter. As the number of Earth-observing devices grows and their data output expands, Orbital Insight’s geospatial analytics platform finds observational truth in an interconnected world. The salinity level now exceeds 100 grams per liter in the South Aral, which is about three times saltier than the ocean.”, On the USGS website, the “Earthshots: Satellite Images of Environmental Change” webpages show the visible changes at many locations on Earth over a 50+ year time period. Dive … For security reasons, there are no published orbit schedules for the imagery spacecraft. A KH-12 is a $1 billion satellite that resembles the Hubble Space Telescope, except it is looking at our planet. The Atlas contains 833 archaeological sites. The first successful CORONA film recovery occurred on 19 August 1960. The first military use of satellites was for reconnaissance. [15], Since October 1967 satellite based weapons systems have been limited by international treaty to conventional weapons only. NASA satellite imagery and astronaut photography reveal where an English alphabet can be found in the landforms of the Earth. Since some of the major military activities of the U.S. army is in foreign territories, the U.S. government needs to subcontract satellite services to foreign carriers headquartered in areas with favorable climate.[18]. Analysis. 1 Description 2 Military satellite industry 3 Use by the U.S. Armed Forces 4 See also 5 References 6 Resources 7 External links Star Wars program A satellite by itself is neither military nor civil. However, the unique imaging geometry of the CORONA satellite cameras, which produced long, narrow film strips, makes correcting spatial distortions in the images very challenging and has therefore limited their use by researchers.”, CAST reports that they have “developed methods for efficient, orthorectification of CORONA imagery and now provides free public access to our imagery database for non-commercial use. “In regions like the Middle East, CORONA imagery is particularly important for archaeology because urban development, agricultural intensification, and reservoir construction over the past several decades have obscured or destroyed countless archaeological sites and other ancient features such as roads and canals. It was rebuilt in 2005 and named the Kok-Aral Dam…..The North Aral has stabilized but the South Aral has continued to shrink and become saltier. In the United States these satellites are operated by the Defense Support Program (DSP). KH-6 LANYARD  image resolution was about 6 feet (1.8 meters). As of 2013, there are 950 satellites of all types in Earth orbit. The first Landsat satellite was launched on 23 July 1972 with two electronic observing systems, both of which had a spatial resolution of about 80 meters (262 feet). The declassified military reconnaissance satellite imagery provides views of the Earth starting in the early 1960s, more than a decade before civilian Earth observation satellites became operational. The US Corona Project used a satellite to spy on Russia during the Cold War and now the images, taken in the 1960s and 1970s, are helping scientists better understand our planet. The United Kingdom also operates military communication satellites through its Skynet system. GEOINT consists of imagery, imagery intelligence and geospatial information.
