What are Indian Low Earth Orbit satellites?
Bengaluru, Mar 27: In a major announcement on Thursday, PM Modi said India has entered its name as an elite space power with successful test of an Anti-Satellite weapon (A-SAT) on a low earth orbit.
A Low Earth Orbit (LEO) is an orbit around earth with an altitude above earth's surface of 2,000 kilometers (1,200 mi). And at this height the satellite will orbit the earth between about 84 and 127 minutes.
The LEO are satellite systems used in telecommunication and internet. They are used mainly for data communication such as email and video conferencing. These orbit at extremely high speeds and are not fixed in space in relation to the earth.
Today, as India shot down an active satellite at very low orbit, at 300 km height, the debris would have entered into the earth atmosphere and burned out. In 2007, China shot down the satellite at 700 km height, this debris didn't enter earth as there is no gravity at that height. The debris is still floating in the space.
There are around 4000 Satellites at this orbit launched by governments and private companies.
