Differentiate between IRS and INSAT Series of Satellites.

The sensors recording the energy that they receive are placed in a near-polar sun synchronous orbit at an altitude of 700 - 900 km. Thesesatellites are known as remote sensing satellites (e.g. Indian RemoteSensing Series). As against these satellites, the weather monitoring andtelecommunication satellites are placed in a Geostationary position (thesatellite is always positioned over its orbit that synchronises with thedirection of the rotation of the earth) and revolves around the earth (coinciding with the direction of the movement of the earth over its axis) at an altitude of nearly 36,000 km (e.g. INSAT series of satellites).
