World’s Largest Sub-Meter High Resolution Satellite Constellation
The DigitalGlobe Constellation
High Performance and Flexibility
Greatest Collection Capacity
The DigitalGlobe constellation of high resolution satellites offers incredible accuracy, agility and collection
capacity, imaging more of the world in the finest level of detail. By 2009, this constellation will be unprec-
edented in the industry, enabling customers around the globe to get the truest view of the world.
The DigitalGlobe Constellation
We currently are able to collect nearly 1 million km2 of quality imagery every day, building an ImageLibrary
already twice the size of any other as well as offering tremendous tasking capacity. And launching October
2009, WorldView-2 will double our collection capacity, add 8-band capability and provide intra-day revisit
to any place on Earth. You choose the world imagery you need and the way you need it—online, offline, on
your mobile device or directly into your GIS—and we deliver real-world perspective you can rely on.
