Positions of geostationary (across centre) and polar orbiting satellites. Geostationary satellites orbit around the Earth at the same rate as the Earth rotates so that the satellites are over the same spot on Earth all the time. This allows them to collect a continuous stream of data for one location. The satellites are positioned 22, 300 miles above the Earth's surface in order to view the Earth's full disk and to maintain their geostationary orbit. Polar orbiting satellites circle the Earth, crossing the poles on each orbit. Typically, polar orbiting satellites are about 500 miles above the Earth's surface. The satellites travel at almost 17, 000mph, allowing them to orbit the Earth in roughly 100 minutes. A polar orbiting satellite is able to cover the whole Earth in less than one day. | |
