WorldView-1

WorldView-1 is a commercial earth observation satellite owned by DigitalGlobe. It was launched September 18, 2007, followed later by the WorldView-2 in 2009. 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.

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
WorldView-1, was built by Ball Aerospace & Technologies. Ball Aerospace built the spacecraft bus and the camera (instrument) using the 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 750,000 km2 per day of half-meter imagery.
