WorldView-1

WorldView-1 (WV 1) is a commercial earth observation satellite owned by DigitalGlobe. WorldView-1 was launched 18 September 2007, followed later by the WorldView-2 in 2009.[4] 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.[5]

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.[5]

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 750,000 square kilometers (290,000 sq mi) per day of half-meter imagery.[5]

Launch

gollark: Seems reasonable.
gollark: Now, rebuilding society will be much easier if your bunker also contains a giant manufacturing facility with everything needed to make at least late-20th-century tech. But that would need people to operate, so add those too, and also extra room and food and whatnot for them.
gollark: Ridiculous. Just make toilet paper out of trees directly.
gollark: And you need entertainment as well, so probably a few hundred terabytes of HDDs so you can store every movie you're ever likely to watch, with redundancy, and you might as well just store every scientific paper and book ever written to help rebuild society.
gollark: I guess you could install that too.
