WorldView-3

WorldView-3

WorldView-3 Satellite Sensor (0.31m)

The WorldView-3 satellite sensor was licensed by the National Oceanic and Atmospheric Administration (NOAA) to collect in addition to the standard Panchromatic and Multispectral bands, eight-band short-wave infrared (SWIR) and 12 CAVIS imagery. The WorldView-3 satellite was successfully launched on August 13, 2014.

WorldView-3 is the first multi-payload, super-spectral, high-resolution commercial satellite sensor operating at an altitude of 617 km. WorldView-3 satellite provides 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short wave infrared resolution and 30 m CAVIS resolution. The satellite has an average revisit time of <1 day and is capable of collecting up to 680,000 km2 per day.

WorldView-3 satellite bears a strong resemblance to WorldView-2 launched on October 8, 2009 in terms of its performance characteristics. The WorldView-3 satellite sensor benefits from significant improvements including cost savings, risk reduction, and faster delivery for its customers.
