WorldView-1 (WV 1) is a commercial Earth observation satellite owned by DigitalGlobe. WorldView-1 was launched on 18 September 2007, followed later by the WorldView-2 in 2009.{{cite web |url=http://www.spaceflightnow.com/news/n0701/07worldview2/ |title=DigitalGlobe announces Ball building WorldView 2 satellite |publisher=Spaceflight Now |access-date=2 February 2007}} First imagery from WorldView-1 was available in October 2007, prior to the six-year anniversary of the launch of QuickBird, DigitalGlobe's previous satellite.{{cite web |url=http://media.digitalglobe.com/index.php?s=press_release_popup&item=135 |title=DigitalGlobe Successfully Launches Worldview-1 |publisher=DigitalGlobe |access-date=21 September 2007 |archive-date=2 March 2009 |archive-url=https://web.archive.org/web/20090302000726/http://media.digitalglobe.com/index.php?s=press_release_popup&item=135 |url-status=dead }}

WorldView-1 was partially financed through an agreement with the National Geospatial-Intelligence Agency (NGA). Some of the imagery captured by WorldView-1 for the NGA is not available to the general public. However, WorldView-1 freed capacity on DigitalGlobe's QuickBird satellite to meet the growing commercial demand for multi-spectral geospatial imagery.

Design

Ball Aerospace built the WorldView-1 satellite bus and camera using an off-axis camera design identical to Quickbird, with the instrument's focal plane being supplied by ITT Exelis. The camera is a panchromatic imaging system featuring half-meter resolution imagery. With an average revisit time of 1.7 days, WorldView-1 is capable of collecting up to {{convert|750,000|km2|sqmi|sp=us}} per day of half-meter imagery.
