Space: The High Eyes Of The Chinese Carrier Killer

But a geostationary orbit is much farther out, beyond the range of smaller anti-satellite launched from the surface, In a geostationary orbit a satellite can cover a much larger area. In the case of Gaofen this is a circular patch of the planet 7,000 kilometers wide off the coast of China. Satellites like Gaofen use an optical sensor which can detect objects at sea as small as 50 meters from a geostationary orbit. An American aircraft carrier is over 300 meters long and when its moving the Gaofen can not only spot, identify and track it but does so in real time. Continue reading
