The most agile and sophisticated constellation of high-resolution commercial Earth imaging sensors

 

QuickBird

 

DigitalGlobe’s QuickBird satellite offers sub-meter resolution imagery, high geolocational accuracy, and large on-board data storage.

The QuickBird satellite is the first in a constellation of sub-meter spacecraft that DigitalGlobe has developed that offers highly accurate, commercial high-resolution imagery of Earth. QuickBird’s global collection of panchromatic and multispectral imagery is designed to support applications ranging from map publishing to land and asset management to insurance risk assessment. DigitalGlobe completed an orbit raise in April of 2011 designed to extend the mission life of the QuickBird sensor. An operational altitude of 482 km was achieved with an expected gradual descent to 450 km by early 2013.
