What is the difference between geostationary and geosynchronous satellite?
Answers
Answer:
Geosynchronous Orbit
About 35,786 kilometers above the Earth’s surface, satellites are in geostationary orbit. From the center of the Earth, this is approximately 42,164 kilometers. This distance puts it in the high Earth orbit category.
At any inclination, a geosynchronous orbit synchronizes with the rotation of the Earth. More specifically, the time it takes for the Earth to rotate on its axis is 23 hours, 56 minutes, and 4.09 seconds, which is the same as a satellite in a geosynchronous orbit.
If you are an observer on the ground, you would see the satellite as if it’s in a fixed position without movement.
This makes geosynchronous satellites particularly useful for telecommunications and other remote sensing applications.
Geosynchronous Orbit
Geostationary Orbit
While geosynchronous satellites can have any inclination, the key difference to geostationary orbit is the fact that they lie on the same plane as the equator.
Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator. This one special quality makes it unique from geosynchronous orbits.
