About WorldView-1
WorldView-1, launched September 2007, is the first of our next-generation satellites—the most agile satellites ever flown commercially. The highcapacity, panchromatic imaging system features half-meter resolution imagery. Operating at an altitude of 496 km, WorldView-1 has an average revisit time of 1.7 days and is capable of collecting over one million sq km per day of half-meter imagery. The satellite is also equipped with state-of-theart geolocation accuracy capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection. WorldView-1 resides in a descending node of 1:30pm.
