What is the difference between a geosynchronous orbit and a 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.
Why is a satellite in 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 is it not possible to put a satellite in geosynchronous orbit above the North Pole?
There cannot be a geostationary satellite at the poles, basically because it would have to be at rest, which cannot happen as it would get pulled by the earth’s gravity and eventually crash to the surface.
What is geosynchronous orbit and why is it important or useful?
Geostationary orbit A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level. It maintains the same position relative to the Earth’s surface.
How do you achieve a geosynchronous orbit?
To achieve a geostationary orbit, a geosynchronous orbit is chosen with an eccentricity of zero, and an inclination of either zero, right on the equator, or else low enough that the spacecraft can use propulsive means to constrain the spacecraft’s apparent position so it hangs seemingly motionless above a point on …
What is a geosynchronous orbit advantages and disadvantages?
➨It is ideal for broadcasting and multi-point distribution applications. ➨Ground station tracking is not required as it is continuously visible from earth all the time from fixed location. ➨Inter-satellite handoff is not needed. ➨Less number of satellites are needed to cover the entire earth.
What is the difference between a geostationary and a geosynchronous satellite?
All geostationary satellites are geosynchronous. Not all geosynchronous satellites are geostationary. Think of it like this: the “synchronous” part of geosynchronous describes the rate of the satellite’s orbit but says nothing about its inclination—the orbit’s angle with respect to the equator.
What are the advantages and disadvantages of geostationary orbit?
The geostationary orbit has the advantage that the satellite remains in the same position throughout the day, and antennas can be directed towards the satellite and remain on track. This factor is of particular importance for applications such as direct broadcast TV where changing directions for the antenna would not be practicable.
What is GSO (a geostationary orbit)?
A Geostationary Orbit (GSO) is a geosynchronous orbit with an inclination of zero, meaning, it lies on the equator. All geostationary satellites are geosynchronous.
What is the purpose of a satellite in orbit?
Satellite in Orbit. From Earth, a satellite in geosynchronous orbit appears to “hover” over one spot on the Equator. This helps the receiving dish on the ground. It can get information from the satellite by pointing at just one point in the sky.
