QuickBird, the first satellite of DigitalGlobe, was launched October 18, 2001 from Vandenberg Air Force Base (USA, California).

The satellite was launched into a 450 km high near-Earth solar-synchronous orbit providing its passage over any area of the Earth every 1-5 days (subject to latitude).
The main advantages of QuickBird are a wide coverage (scene size is 16.5x16.5 km), high metric accuracy and possibility of ordering complex polygons.
Currently, an archive of panchromatic and multispectral images is available around the world.
