Pleiades

 

Pléiades it is an optical observation system consisting of a twin satellites Pléiades 1A and 1B, which provide imaging with a resolution of 50 cm. Guarantee a daily return visit any place on Earth for both civilian and military purpose.

Pleiades satellites are programmed at approx. 8 hours. This translates into a very short waiting period between ordering and the execution and delivery of images. For example, take a picture of Warsaw requires its report no later than 5:30 am (daylight saving time)at the same day. Image after it is available usually after about an hour of execution – or approximately 1pm. Pleiades are the only commercial satellites with a resolution 50 cm with a daily return visit.
