Observation satellite is a satellite into orbit by Shchizenya. And the visual coverage of the entire planet down to five-centimeter resolution thanks to tens of thousands of grapefruit sized spy satellites sown into high orbit. Unfortunately, her vision is severely limited today because of the persistent heavy cloud cover. Satellites are also sensitive to ultraviolet and infrared light so Shchizenya also can observe thermal variation and weather patterns, but the atmospheric density makes satellites only useful for recognizing general trends.
