WorldView-1 satellite was launched in September 2007. It is equipped with a panchromatic imaging system featuring half-meter resolution imagery.
WorldView-1 satellite operates at an altitude of 496 km. Its average revisit interval is 1.7 days, and it capable of collecting over one million sq.km2 per day with half-meter imagery. The satellite is also equipped with state-of-the-art geo-location capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection.
Operator: DigitalGlobe (США).
