QuickBird was a high-resolution commercial Earth observation satellite, [3] owned by DigitalGlobe, launched in 2001 and reentered after orbit decay in 2015. [4] QuickBird used Ball Aerospace's Global Imaging System 2000 (BGIS 2000). [1] The satellite collected panchromatic (black and white) imagery at 61 centimeter resolution and multispectral imagery at 2.44- (at 450 km) to 1.63-meter (at 300 km) resolution, as orbit altitude is lowered during the end of mission life. [5]
At this resolution, detail such as buildings and other infrastructure are easily visible. However, this resolution is insufficient for working with smaller objects such as a license plate on a car. The imagery can be imported into remote sensing image processing software, as well as into GIS packages for analysis.
Contractors included Ball Aerospace & Technologies, Kodak and Fokker Space. Original plans called for a constellation of three QuickBird satellites scheduled to be in orbit by 2008. In the end, two QuickBird satellites, QuickBird I and II, made it to launch pad. However, only QuickBird II made it successfully into orbit (QuickBird I suffered launch failure). Thus QuickBird II satellite is usually referred to simply as QuickBird, and by the name QuickBird is usually meant the satellite QuickBird II.
Prior to QuickBird I and II, DigitalGlobe launched the EarlyBird 1 successfully in 1997 but the satellite lost communications after only four days in orbit due to power system failure. [2]
The first QuickBird, QuickBird I (or QuickBird 1, QB 1, COSPAR 2000-074A) was launched 20 November 2000, by EarthWatch from the Plesetsk Cosmodrome in Russia by a Kosmos-3M rocket. QB-1 failed to reach planned orbit due to launch vehicle failure and was declared a failure. The satellite re-entered next day still attached to the upper stage of the rocket. [6] [7] The QB-1 satellite was in construction similar to QuickBird 2 satellite (described above and below in this article), which became later known simply as QuickBird. [8]
QuickBird II (also QuickBird-2 or Quickbird 2, QB-2, COSPAR 2001-047A) or as it was later known, simply QuickBird, was launched for DigitalGlobe October 18, 2001 from the Vandenberg Air Force Base, California, aboard a Boeing Delta II rocket. [2] The satellite was initially expected to collect at 1 meter resolution but after a license was granted in 2000 by the U.S. Department of Commerce / NASA, DigitalGlobe was able launch the QuickBird II with 0.61 meter panchromatic and 2.4 meter multispectral (previously planned 4 meter) resolution. [2] [8]
In April 2011, the Quickbird satellite was raised from an orbit of 450 km (280 mi) to 482 km (300 mi). [9] The process, started in March 2011, extended the satellite's life. Before the operation the useful life of Quickbird was expected to drop off around mid-2012 but after the successful mission, the new orbit prolonged the satellite life into early 2015.
The last picture was acquired on December 17, 2014. On January 27, 2015, QuickBird re-entered Earth's atmosphere.

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.
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.
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.
Monitor-E was the first Russian satellite of a fleet of newly designed, small Earth observing satellites. It was launched 26 August 2005 at 18:34 UTC from Plesetsk Cosmodrome, and placed in a Sun-synchronous orbit of 524 by 544 km.
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.
Resurs-DK No.1, also called Resurs-DK1, was a commercial Earth observation satellite capable of transmitting high-resolution imagery to the ground stations as it passed overhead. The spacecraft was operated by NTs OMZ, the Russian Research Center for Earth Operative Monitoring.
