WV110  

Definition

  • WV110 was designed and developed at ITT Corporation's Space Systems Division of Rochester, NY. The objective of the WV110 instrument is to provide high-resolution panchromatic as well as 8-band multispectral imagery for enhanced mapping and monitoring applications (including stereo imagery due to rapid retargeting capability). In September 2008, BATC started with the integration of the WV110 camera. On Feb. 24, 2009 the WV110 camera had been integrated into the WorldView-2 spacecraft and system-level testing has commenced.
