SkySat-1 was launched on November 21, 2013 from Yasny, Russia on a Dnepr rocket. SkySat-1 is the first of a planned constellation of small 24 Earth observation satellites. SkySat-1 has a mass of 100 kg and is capable of producing sub-meter resolution imagery and high-definition video. The satellite will operate in a circular orbit at approximately 450 km above the earth, significantly lower than the proposed 617 km high orbit of Worldview-3.
The first images returned from SkySat-1 have been published. They were taken over Perth, Australia, on December 4, 2013 at 10:25AM and are untuned and uncalibrated. The detail is incredible for a satelite weighting almost 30x less than the 2,800 kg Worldview-2.
