Specifications

downlink: 8.025-8.400 GHz
uplink: 2085.6875 MHz

CAVIS (which stands for Cloud, Aerosol, Water Vapor, Ice, Snow) will monitor the atmosphere and provide correction data to improve WorldView-3's imagery when it images Earth objects through haze, soot, dust or other obscurants. CAVIS has also been integrated with the spacecraft.

Like previous Worldview satellites, it carries Control Moment Gyroscopes (CMGs) which enable to reorient a satellite over a desired collection area in 4-5 seconds, compared to 30-45 seconds needed for traditional reaction wheels.
