Difference between Geostationary and Geosynchronous
Geostationary and Geosynchronous are two types of orbits used by satellites around the Earth.
The main difference between Geostationary and Geosynchronous is that a Geostationary satellite stays fixed in one spot above the Earth’s equator, while a Geosynchronous satellite’s position can change slightly over time.
Before we move to the differences, let’s understand what are Geostationary and Geosynchronous:
- Geostationary: A geostationary orbit is a path high above Earth where satellites move at the same speed as the planet. This means they stay in the same spot in the sky all the time.
- Geosynchronous: A geosynchronous orbit is also a path for satellites, but here they don’t stay in one spot. They move at the same speed as Earth but can shift from north to south.
Now, let’s move to Geostationary vs Geosynchronous:
Major differences between Geostationary and Geosynchronous
| Geostationary | Geosynchronous |
|---|---|
| A geostationary orbit remains at a fixed position in the sky as observed from the Earth’s surface, | A geosynchronous orbit can appear to move in the sky throughout the day. |
| Geostationary orbits are always located above the Earth’s equator, | Geosynchronous orbits can be inclined at any angle to the equator. |
| Satellites in geostationary orbit follow the Earth’s rotation exactly, | Satellites in geosynchronous orbit may not match the Earth’s rotation perfectly. |
| Geostationary orbits are a type of geosynchronous orbit, | Not all geosynchronous orbits are geostationary. |
| Satellites in a geostationary orbit are ideal for weather monitoring and communication purposes, | Satellites in a geosynchronous orbit are often used for different purposes, such as spying or studying the Earth’s magnetic field. |
That’s it.
Note that sometimes, the question might also be asked as “distinguish between Geostationary and Geosynchronous”.
