Why are communication satellites placed in a geostationary orbit?
Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas (located on Earth) do not have to rotate to track them but can be pointed permanently at the position in the sky where the satellites are located.
Why are geostationary satellites far from Earth?
The satellites must also be located far enough away from each other so their communications don’t interfere with each other, which could mean a separation of anything between 1 and 3 degrees. As technology has improved, it’s possible to pack more satellites into a smaller spot.
What is the area coverage range for Irnss satellites?

Why is IRNSS needed?
The IRNSS is an independent regional navigation satellite system developed by India. It is designed to provide accurate position information service to assist in the navigation of ships in the Indian Ocean waters.
What is the use of IRNSS satellite?
IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area.
How many satellites are there in IRNSS?
The fully deployed IRNSS system consists of 3 satellites in GEO orbit and 4 satellites in GSO orbit, approximately 36,000 km altitude above earth surface.
What is a geosynchronous satellite called?
Geosynchronous Satellites. The orbits where geosynchronous satellites revolve are known as geosynchronous orbits. A satellite that’s in a geosynchronous orbit appears at exactly the same spot in the sky after a period of one sidereal day, when viewed from a specific position on Earth.
Why IRNSS is called the skeleton of NAVIC?
This is because IRNSS satellites are actually used to be the skeleton of NAVIC or the Indian Regional Navigation System. It consists of mainly 7 satellites… and is placed at an orbit of 36,000 km around the Earth since it is the ideal position for GPS tracking satellites.
What is a geosynchronous orbit?
The orbits where geosynchronous satellites revolve are known as geosynchronous orbits. A satellite that’s in a geosynchronous orbit appears at exactly the same spot in the sky after a period of one sidereal day, when viewed from a specific position on Earth. Geosynchronous orbits that are circular in shape have a radius of 26,199 miles (42,164 km).
