WorldView-2 (WV 2) is a commercial Earth observation satellite owned by DigitalGlobe. WorldView-2 provides commercially available panchromatic imagery of 0.46m (01.51feet) resolution, and eight-band multispectral imagery with 1.84m (06.04feet) resolution.[4]
It was launched 8 October 2009 to become DigitalGlobe's third satellite in orbit, joining WorldView-1 which was launched in 2007 and QuickBird which was launched in 2001.[5] It takes a new photograph of any place on Earth every 1.1 days.[6]
Ball Aerospace built the spacecraft, which includes an optical telescope that can image objects 18inches in diameter.
WorldView-2 was launched 8 October 2009 from Vandenberg Air Force Base on a Delta II flying in the 7920 configuration. The launch vehicle was provided by the United Launch Alliance and launch services were administered by Boeing.[7]
On 19 July 2016, the Joint Space Operations Center reported a debris causing event of at least 9 observable pieces, after which DigitalGlobe demonstrated the satellite to still be functional by releasing an image of downtown Oakland, California.[8] [9]
