WorldView-1 was launched on 18 September 2007 and WorldView-2 on 8 October 2009. Both were launched on Delta 7920 rockets from the Vandenberg Air Force Base. WorldView-1 is foreseen to last until 2018, while WorldView-2 is planned to last until 2017.
Both have a sun-synchronous orbit and descend over the equator during each orbit at 10:30 am. WorldView-1 orbits at an altitude of 496 km, has an orbital period of 94.6 minutes, with an average revisit time of 1.7 days. It carries a panchromatic imaging sensor. WorldView-2 orbits at an altitude of 770 km. has an orbital period of 100 minutes and carries a multispectral imaging sensor.
The main applications for the WoldView satellites are very high resolution mapping, change detection and stereo 3D imaging.
