WorldView-1(WV 1) is a commercialEarth observation satelliteowned byDigitalGlobe.WorldView-1 was launched on 18 September 2007, followed later by theWorldView-2in 2009.[4]First imagery fromWorldView-1was available in October 2007, prior to the six-year anniversary of the launch ofQuickBird,DigitalGlobe's previous satellite.[5]
WorldView-1 was partially financed through an agreement with theNational 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'sQuickBirdsatellite to meet the growing commercial demand for multi-spectralgeospatialimagery.[5]
Design[edit]
Ball Aerospacebuilt the WorldView-1satellite busand camera using an off-axis camera design identical to Quickbird, with the instrument's focal plane being supplied byITT Exelis.The camera is apanchromaticimaging 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 square kilometers (290,000 sq mi) per day of half-meter imagery.[5]
