DMC Constellation

The DMC Constellation provides rapid repeat coverage of the largest countries, regions and even continents. The DMC Constellation is capable of acquiring multispectral imagery at 22-24m resolution and panchromatic imagery at 12m.
Image size is adjustable up to very large images (i.e. 640 x 1,300km). Access to the DMC Constellation data supports our users in the development of applications and services across various markets such as wide-area change detection, forestry, agriculture, disaster management, land cover mapping and environmental monitoring.
The DMC Constellation offers multiple options for new imagery tasking through the "OneTasking" offer, as well as an extensive imagery archive going back to 2004.
ALSAT-1B joined the DMC Constellation offer in 2018 as a key continuity mission, and brings additional spectral bands and enhanced coverage frequency to the constellation.
