Geostationary satellite is generally set at an altitude of about 36.000 km. But generally Polar satellites are positioned at an altitude of about 850 km, so that circle the earth every 100 minutes or more.

Polar's first satellite launched on February 24, 1996 and the national aeronautics and space administration (NASA). This is the second satellite to be launched under the international science geospace project. Tide / PSI investigation is the duty of the Polar satellite.

The purpose of Polar satellites gather information about Mionzi and other dangerous atmosphere. While satellite protection in the high atmosphere, the possibility that satellite instruments can be destroyed by the sun Mionzi dangerous.

Polar satellites using two visible light and infrared (IR) radiation measurements of heat and humidity in the atmosphere of the earth. Polar satellites also help record and soil water and sea water temperature, and monitor clouds and water / ice boundary. Polar satellite to receive, measure, process, and Retransmit data from balloons, buoys, and automatic stations distributed around the world village. These satellites can also carry transponders to seek help and rescue Search dropped an airplane or ship in distress.

Polar satellites to measure the Antarctic ozone levels, and long-term environmental measurements used to help change the world climate studies. Polar orbiting satellite earth also known origin (LEO). The Polar satellite you can only see a post or a small area in the world at that time. Polar orbit that crosses the equator special and all latitudes at the same time every day is sun synchronous orbit satellites.
