WorldView-3 satellite
WorldView-3 is the first in the industry commercial satellite with multi-payload, super-spectral and high-resolution. It operates at an altitude of 617 km and provides 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short-wave IR resolution and 30 m CAVIS resolution. WorldView-3 can collect up to 680,000 km2 per day due to the average revisit time of <1 day. The satellite is urged to enhance the DigitalGlobe collection capacity.
