DigitalGlobe was 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. [2]
The company's "WorldView" satellites should not be confused with the unrelated WorldView company (a stratospheric balloon operator).
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. [3] 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. [4] The company was initially funded with private financing from Silicon Valley sources and interested corporations in North America, Europe and Japan. Dr. Scott was head of the Lawrence Livermore Laboratories "Brilliant Pebbles" and "Brilliant Eyes" projects which were part of the Strategic Defense Initiative. Doug Gerull was the executive in charge of the Mapping Sciences division at the Intergraph Corporation. [5] The company's first remote sensing license from the United States Department of Commerce allowed it to build a commercial remote sensing satellite capable of collecting images with 3 m (9.8 ft) resolution. [3]
In 1995, the company became EarthWatch Incorporated, merging WorldView with Ball Aerospace & Technologies Corp.'s commercial remote sensing operations. [6]
In September 2001, EarthWatch became DigitalGlobe. [7]
In 2007, DigitalGlobe acquired online imagery provider GlobeXplorer to extend its imagery distribution capabilities via online APIs and web services. [8]
In 2011, DigitalGlobe was inducted into the Space Foundation's Space Technology Hall of Fame for its role in advancing commercial Earth-imaging satellites. [9]
In 2013, DigitalGlobe purchased GeoEye. [10] [11]
In February 2017, MacDonald, Dettwiler and Associates (MDA) and DigitalGlobe reached an agreement for MDA to acquire DigitalGlobe for US$2.4 billion. [12] As of May 2017, DigitalGlobe's image catalog contains 100 petabytes worth of data, and grows by 100 terabytes each day. [13] As of 5 October 2017, MDA has announced it has completed its acquisition of DigitalGlobe. [2] On 5 October 2017, DigitalGlobe and MDA Holdings Company merged to become Maxar Technologies [14]
On 30 December 2019, the company announced that it had entered into a definitive agreement to sell MDA to a consortium of financial sponsors led by Northern Private Capital for CAD$1 billion (US$765 million). The sale included all of MDA's Canadian businesses, encompassing ground stations, radar satellite products, robotics, defense, and satellite components, representing approximately 1,900 employees. [15]
On 8 April 2020, the sale of the MDA assets to NPC officially closed. The newly formed privately held Canadian company was named MDA. [16] [17]
EarlyBird-1 (COSPAR 1997-085A) commercial Earth imaging satellite was built for EarthWatch Inc. by CTA Space Systems (later part of Orbital Sciences Corporation) and launched on 24 December 1997, from the Svobodny Cosmodrome by a Start-1 launch vehicle. [18] It had a mass of 317 kg (699 lb) and a design life of 3 years (fuel reserves for 5 years). It included a panchromatic (black-and-white) camera with a 3 m (9.8 ft) resolution and a multispectral (color) camera with a 15 m (49 ft) resolution. The imaging sensor was derived from a 1998-cancelled NASA satellite called Clark (SSTI 2). [19] EarlyBird-1 was the first commercial satellite to be launched from the Svobodny Cosmodrome. Although the launch was successful, the satellite lost communications after only four days in orbit due to power system failure. [20]
IKONOS was launched 24 September 1999. It was the world's first high-resolution commercial imaging satellite to collect panchromatic (black-and-white) images with 0.8 m (2 ft 7 in) resolution and multispectral (color) imagery with 3.2 m (10 ft) resolution. [21] On 31 March 2015, IKONOS was officially decommissioned after more than doubling her mission design life, spending 5,680 days in orbit and making 83,131 trips around the Earth. [22]
QuickBird, launched on 18 October 2001, [6] was DigitalGlobe's primary satellite until early 2015. It was built by Ball Aerospace, and launched by a Boeing Delta II. It is in a 450 km (280 mi) altitude, 98° inclination Sun-synchronous orbit. An earlier launch attempt resulted in the loss of QuickBird-1; after this, the second satellite of the series, QuickBird-2 was launched and it is this satellite that became known simply as QuickBird (as no other QuickBird satellites were launched). It included a panchromatic camera with a 60 cm (24 in) resolution and a multispectral camera with a 2.4 m (7 ft 10 in) resolution. On 27 January 2015, QuickBird was de-orbited, exceeding her initial life expectancy by nearly 300%. [22]
The GeoEye-1 satellite collects images at 0.41 m (1 ft 4 in) panchromatic (black-and-white) and 1.65 m (5 ft 5 in) multispectral resolution. The satellite can collect up to 350,000 km2 (140,000 sq mi) of multispectral imagery per day. This is used for large-scale mapping projects. GeoEye-1 can revisit any point on Earth once every three days or sooner.
Ball Aerospace built WorldView-1. [23] It was launched on 18 September 2007 from Vandenberg Air Force Base on a Delta II 7920-10C. Launch services were provided by United Launch Alliance (ULA). The National Geospatial-Intelligence Agency (NGA) is expected to be a major customer of WorldView-1 imagery. [24] It included a panchromatic only camera with a 50 cm (20 in) maximum resolution.
Ball Aerospace built WorldView-2. It was launched on 8 October 2009. DigitalGlobe partnered with Boeing commercial launch services to deliver WorldView-2 into a Sun-synchronous orbit. [25] [26] The satellite includes a panchromatic sensor with a 46 cm (18 in) maximum resolution and a multispectral sensor of 184 cm (72 in) [27]
Ball Aerospace built WorldView-3. It was launched on 13 August 2014. It has a maximum resolution of 25 cm (9.8 in). WorldView-3 operates at an altitude of 617 km (383 mi), where it has an average revisit time of less than once per day. Over the course of a day it is able to collect imagery of up to 680,000 km2 (260,000 sq mi). [28]
Previously, DigitalGlobe was only licensed to sell images with a higher resolution than 50 cm (20 in) to the U.S. military. [29] However, DigitalGlobe obtained permission, in June 2014, from the United States Department of Commerce, to allow the company to more widely exploit its commercial satellite imagery. The company was permitted to offer customers the highest resolution imagery available from their constellation. Additionally, the updated approvals allowed the sale of imagery to customers at up to 25 cm (9.8 in) panchromatic and 100 cm (39 in) multispectral ground sample distance (GSD), beginning six months after WorldView-3 became operational. WorldView-3 was launched aboard a United Launch Alliance Atlas V launch vehicle in the 401 configuration on 13 August 2014, at 18:30 UTC from Vandenberg Space Launch Complex 3 (SLC-3E) at Vandenberg Air Force base. [30]
WorldView-3 is the industry's first multi-payload, super-spectral, high-resolution commercial satellite. [31]
The WorldView-4 satellite was designed to provide panchromatic images at a highest resolution of 31 cm (12 in), and multispectral images at 124 cm (49 in). [32] Originally named GeoEye-2, the spacecraft was designed and built by Lockheed Martin, [33] while the camera payload was provided by ITT Corporation. [34]
Following the merger of GeoEye and DigitalGlobe, in 2013, DigitalGlobe announced that GeoEye-2 would be completed as a ground spare to be launched if or when required. [35] [36] It was renamed to WorldView-4 in July 2014, when the company announced that it would be launched in Fall 2016. [37] [38] It was launched on 11 November 2016.
In January 2019, the company reported the failure of a control moment gyroscope on the satellite, rendering it inoperable. [39]
Currently being built by Maxar Technologies, WorldView Legion is Maxar's next generation of Earth observation satellites. WorldView Legion comprises six satellites planned to launch in 2023 [40] into a mix of Sun-synchronous and mid-latitude orbits. [41] [42] These satellites will replace imaging capability currently provided by Maxar's WorldView-1, WorldView-2 and GeoEye-1 Earth observation satellites. [43]
The six WorldView Legion satellites are contracted to launch on three flight-proven SpaceX Falcon 9 launch vehicles. [44]
DigitalGlobe's customers range from urban planners, to conservation organizations like the Amazon Conservation Team, [45] to the U.S. federal agencies, including NASA [7] and the United States Department of Defense's National Geospatial-Intelligence Agency (NGA). [46] Much of Google Earth and Google Maps high resolution-imagery is provided by DigitalGlobe. [47]
DigitalGlobe's main competitor is Airbus with Spot and Pleiades satellites. [48]
Landsat 7 is the seventh satellite of the Landsat program. Launched on 15 April 1999, Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat program is managed and operated by the United States Geological Survey, and data from Landsat 7 is collected and distributed by the USGS. The NASA WorldWind project allows 3D images from Landsat 7 and other sources to be freely navigated and viewed from any angle. The satellite's companion, Earth Observing-1, trailed by one minute and followed the same orbital characteristics, but in 2011 its fuel was depleted and EO-1's orbit began to degrade. Landsat 7 was built by Lockheed Martin Space Systems.
SPOT is a commercial high-resolution optical Earth imaging satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES in the 1970s and was developed in association with the SSTC and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. The SPOT system includes a series of satellites and ground control resources for satellite control and programming, image production, and distribution. Earlier satellites were launched using the European Space Agency's Ariane 2, 3, and 4 rockets, while SPOT 6 and SPOT 7 were launched by the Indian PSLV.
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. By extension, a panchromatic sensor is an image sensor sensitive to the whole visible spectrum. A panchromatic image is the resulting picture.
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.
IKONOS was a commercial Earth observation satellite, and was the first to collect publicly available high-resolution imagery at 1- and 4-meter resolution. It collected multispectral (MS) and panchromatic (PAN) imagery. The capability to observe Earth via space-based telescope has been called "one of the most significant developments in the history of the space age", and IKONOS brought imagery rivaling that of military spy satellites to the commercial market. IKONOS imagery began being sold on 1 January 2000, and the spacecraft was retired in 2015.
QuickBird was a high-resolution commercial Earth observation satellite, owned by DigitalGlobe, launched in 2001 and reentered after orbit decay in 2015. QuickBird used Ball Aerospace's Global Imaging System 2000. The satellite collected panchromatic imagery at 61 centimeter resolution and multispectral imagery at 2.44- to 1.63-meter resolution, as orbit altitude is lowered during the end of mission life.
TerraServer was a commercial website specializing in aerial and satellite imagery which was originally launched in 1997. It is owned and operated by TerraServer.com, Inc. in Raleigh, North Carolina. The company was previously named Aerial Images until May 2002 when the assets of Aerial Images were sold and the company renamed itself TerraServer.com, Inc.
Earth Satellite Corporation (EarthSat), an American company, was a pioneer in the commercial use of Earth observation satellites. Founded in 1969, EarthSat was first headquartered in Washington, D.C., and later moved its offices to Bethesda, Maryland, and finally to Rockville, Maryland, in the late 1980s. In 2001, EarthSat was acquired by MacDonald, Dettwiler and Associates Ltd. (MDA) of Vancouver, British Columbia. In August 2005, EarthSat was incorporated as MDA Federal Inc., the U.S. operation of MDA Geospatial Services.
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.
GeoEye Inc. was an American commercial satellite imagery company based in Herndon, Virginia. GeoEye was merged into the DigitalGlobe corporation on January 29, 2013.
Pansharpening is a process of merging high-resolution panchromatic and lower resolution multispectral imagery to create a single high-resolution color image. Google Maps and nearly every map creating company use this technique to increase image quality. Pansharpening produces a high-resolution color image from three, four or more low-resolution multispectral satellite bands plus a corresponding high-resolution panchromatic band:
Low-res color bands + High-res grayscale band = Hi-res color image
