Ball Aerospace & Technologies has completed a series of environmental tests on WorldView-3, the next generation commercial remote-sensing satellite built for DigitalGlobe, a global provider of high-resolution earth imagery solutions.
The satellite and its integrated sensors and electronics successfully completed thermal vacuum, acoustic, vibration, and pyro-separation testing to confirm the design integrity of the spacecraft. Electromagnetic interference and electromagnetic compatibility will complete on April 23.
New to WorldView-3 is a Ball Aerospace-built atmospheric instrument called CAVIS, which stands for Cloud, Aerosol, water Vapor, Ice, Snow. CAVIS 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.
WorldView-3 is the first multi-payload, super-spectral, high-resolution commercial satellite for earth observations and advanced geospatial solutions. Operating at an expected altitude of 617 km, WorldView-3 collects imagery with 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short-wave infrared (SWIR) resolution, and 30 m CAVIS resolution. This level of resolution performance would be fundamentally impossible without the 1.1 m aperture telescope built by Exelis and carried by WorldView-3, which allows for a breadth of applications unmatched by smaller, lower-performance satellites. Currently, U.S. government restrictions require commercial satellite imagery provided to non-U.S. government customers be limited to no less than 50 cm panchromatic, 2.0 m multispectral, or 7.5 meter SWIR.
