multispectral

QuickBird was a high-resolution commercial

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

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]

QuickBird I

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

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

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]

Mission Extension

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.

Decaying

The last picture was acquired on December 17, 2014. On January 27, 2015, QuickBird re-entered Earth's atmosphere.
