Correct option is B
The
INSAT (Indian National Satellite) series consists of
geosynchronous satellites. These satellites revolve around the Earth at the same rotational speed as the Earth, allowing them to appear stationary relative to a specific point on the surface. INSAT satellites are used for communication, broadcasting, meteorology, and disaster warning services in India.
Information Booster:
1.
Geosynchronous Satellites: Orbit the Earth at a fixed position relative to the Earth's surface, typically at an altitude of approximately 35,786 km.
2. Geosynchronous Orbit: Matches the Earth's rotation, enabling continuous coverage of a specific area.
3. Polar Orbits (Sun-synchronous): Cross the equator at consistent local solar times, ideal for Earth observation satellites like IRS and LANDSAT.
Additional Knowledge:
· I.R.S. (Indian Remote Sensing Satellites): Operates in polar orbits, used for resource monitoring and mapping.
· LANDSAT: A U.S. satellite series used for Earth observation, primarily in sun-synchronous orbit.
· SPOT H.R.V.: French satellite series for high-resolution Earth observation, also in sun-synchronous orbit.
