US: Ball Aerospace & Technologies has completed a series of environmental tests on WorldView-3, remote-sensing satellite built for DigitalGlobe. The satellite and its integrated sensors and electronics underwent completed thermal vacuum, acoustic, vibration, and pyro-separation testing. Electromagnetic interference and electromagnetic compatibility will complete on April 23.
The WorldView-3 has 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.
WorldView-3 is the first multi-payload, super-spectral, high-resolution commercial satellite for earth observations and advanced geospatial solutions. By carrying forward the satellites' advanced Control Moment Gyroscopes (CMGs), WorldView-3 builds upon WorldView-2 and WorldView-1 technology.
WorldView-3 is expected to launch from Vandenberg Air Force Base aboard a United Launch Alliance Atlas 5 rocket in mid-August. WorldView-3 is the fifth satellite built by Ball Aerospace for DigitalGlobe and the fourth that will join the remote-sensing constellation.
