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 . ... While the geostationary orbit lies on the same plane as the equator, the geosynchronous satellites have a different inclination.
Are geosynchronous and geostationary satellites the same?
In technical terminology, the geosynchronous orbits are often referred to as geostationary if they are roughly over the equator , but the terms are used somewhat interchangeably. Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, or geostationary Earth orbit.
What is non geosynchronous satellite?
Non-geostationary (NGSO) satellites occupy a range of orbital positions (LEO satellites are located between 700km-1,500km from the Earth, MEO satellites are located at 10,000km from the Earth), and do not maintain a stationary position, but instead move in relation to the Earth’s surface.
What is the difference between a geostationary geosynchronous satellite and a polar orbiting satellite?
While polar orbits have an inclination of about 90 degrees to the equator, geostationary orbits match the rotation of the Earth . ... Out of the three types of orbits (low, medium and high Earth orbits), polar orbits often fall into low Earth orbits. Learn more about geostationary and geosynchronous orbits.
What is special about a geosynchronous satellite?
Geostationary satellites have the unique property of remaining permanently fixed in exactly the same position in the sky as viewed from any fixed location on Earth , meaning that ground-based antennas do not need to track them but can remain fixed in one direction.
How high are geosynchronous satellites?
Geostationary orbit (GEO)
In order to perfectly match Earth’s rotation, the speed of GEO satellites should be about 3 km per second at an altitude of 35 786 km . This is much farther from Earth’s surface compared to many satellites.
What are the advantages of a non-geostationary satellite?
The advantages of NGSO systems are the lower latency, smaller size and lower losses in comparison to GEO satellite systems and that when a constellation is shaped a global coverage can be achieved. Now, new systems have been put in operation and are planned which are using NGSO satellites.
What are the 4 types of satellites?

- Geocentric Orbit type staellies – LEO, MEO, HEO.
- Global Positioning System (GPS)
- Geostationary Satellites (GEOs)

What are the application of geostationary satellite?
Geostationary satellite imagery has been used for tracking volcanic ash, measuring cloud top temperatures and water vapour, oceanography, measuring land temperature and vegetation coverage , facilitating cyclone path prediction, and providing real time cloud coverage and other tracking data.
Do geosynchronous satellites move?
A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. ... Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot.
What is the lowest orbit possible?
A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.
How fast do Geostationary satellites travel?
The aptly titled geosynchronous orbit is described in detail: “At an altitude of 124 miles (200 kilometers), the required orbital velocity is just over 17,000 mph (about 27,400 kph). To maintain an orbit that is 22,223 miles (35,786 km) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph) .
What are the advantages of geosynchronous satellites?
Advantages of geostationary satellites:
As geostationary satellites are positioned at a high altitude (a distance of 3.57 × 10 7 m away from the surface of the Earth), it can view a large section of the Earth and scan the same area frequently . Hence, they are ideal for meteorological applications and remote imaging.
Can you see geostationary satellites?
The GOES geostationary satellites are about 22,300 miles above Earth’s Equator and require a telescope to see, but you may be able to see a polar orbiting satellite (orbiting about 500 miles about Earth’s surface) with just a pair of binoculars or, if it’s dark enough, just your eyes!
Is Moon a geostationary satellite?
Our Moon is obviously not in synchronous , or more specifically geosynchronous orbit about the Earth. The period of its orbit around the Earth is not the same as our sidereal day; in fact, it takes the Moon about 27.3 of our days to complete one orbit of our Earth.
