Question

difference between Geostationary and sunsynchronous satellite

Answer 1

geostationary satellites are situated near the equator of earth and are three in no. it revolves around the earth with the same speed of rotation of earth so it is called stationary

Answer 2

geostationary satellite
A geosynchronous orbit is an orbit around the Earth, where the object orbits once per day. A common kind of geosynchronous orbit is called a geostationary orbit, where the object orbits above the same part of the Earth at all times.

This is an extremely useful type of orbit and is used for anything where a satellite needs to send or receive signals from the same part of the Earth all the time. It's used for cell phone satellites, television satellites, weather satellites, as well as some military satellites.

Sun-Synchronous Orbits

A sun-synchronous orbit is an orbit around the Earth, where the movement of the satellite always looks the same when viewed from the Sun. A satellite in a sun-synchronous orbit still orbits the Earth, but does so in such a way that over the course of the day, its distance to the Sun will change in a consistent pattern no matter the time of year.
