worldview 4

Introducing WorldView-4, a multispectral, high-resolution commercial satellite. Operating at an expected altitude of 617 km, WorldView-4 provides 31 cm panchromatic resolution, and 1.23 m multispectral resolution. WorldView-4 has an average revisit time of <1 day and is capable of collecting up to 680,000 sq km per day, further enhancing the DigitalGlobe collection capacity for more rapid and reliable collection

Very high-resolution - Panchromatic 31 cm - Visible & near-infrared 1.24 m

Industry-leading geolocation accuracy

Industry-leading geolocation accuracy

High capacity in various collection modes

Bi-directional scanning

Rapid retargeting using Control Moment Gyros (>2x faster than any competitor)

Direct Access tasking from and image transmission to customer sites

Daily revisits

Simultaneous, high resolution, super-spectral imagery

Large area mono and stereoscopic collection eliminates temporal variations

Precision geolocation possible without ground control points

Global capacity of 680,000 sq km per day, which doubles 30 cm collection capability and the ability to collect for large-area mapping projects at the highest commercially available resolution
