Satellite family: Digital Globe - MDA ConstellationDigitalGlobe is an American supplier of very high-resolution commercial satellite imagery. DigitalGlobe owns and operates a fleet of Earth imaging satellites including IKONOS, Quickbird, GeoEye-1 and WorldView 1,2,3 and the recently launched WorldView 4 capable of seeing objects as small as 30 cm.
On February 2017, DigitalGlobe has agreed to combine with MDA, the Canadian radar, telecommunications, and imagery corporation.
With IKONOS, a new era of 1m spatial resolution imagery began for spaceborne instruments in the field of civil Earth observation. IKONOS-2 was the world’s first commercial satellite to collect panchromatic images with 80 cm resolution and multispectral imagery with 3.2 meter resolution. It was decommissioned in March 2015 ending a 15 year mission life.
