With its improved agility, WorldView-2 is able to act like a paintbrush, sweeping back and forth to collect very large areas of multispectral imagery in a single pass. WorldView-2 alone is able to collect nearly 1 million km2 every day, doubling the collection capacity of our constellation to nearly 2 million km2 per day. And the combination of WorldView-2’s increased agility and high altitude enables it to typically revisit any place on earth in 1.1 days, revisit time drops below one day and never exceeds two days, providing the most same-day passes of any commercial high resolution satellite.
The WorldView-2 imaging payload is the second such system engineered and manufactured by ITT Space Systems Division for DigitalGlobe. WorldView-2 operates at an altitude of 770 kilometers, and the advanced on-board imaging system can capture pan-sharpened, multispectral images (with better than 0.46-meter resolution) from almost 500 miles above the Earth. These images supply unprecedented detail and geospatial accuracy, further expanding the applications for satellite imagery in both commercial and government markets. Added spectral diversity provides the ability to perform precise change detection and mapping.
In addition to numerous other technical improvements, WorldView-2 also has the ability to accommodate direct tasking, which will allow select customers around the world to load imaging profiles directly up to the spacecraft and execute delivery of the data directly down to their own ground stations.
