Why is geosynchronous orbit an altitude, rather than a velocity?
Mar 26, 2020 · What Are Uses of Geostationary Satellites? By Staff Writer Last Updated March 26, 2020 Most common geostationary satellites are either weather satellites, communication satellites relaying signals between two or more ground stations and satellites that broadcast signals to a large area on the planet. The best example of the latter is satellite TV.

What are the advantages of geostationary satellites?
Ans. The advantages of geostationary satellites are as follows: 1 Geostationary satellites provide us with high temporal resolution data. 2 The satellites are always fixed to a particular position in the sky with respect to the earth. This makes tracking down extremely simplified and cost-effective. 3 These satellites have important applications in defence and intelligence, communication broadcasting and weather forecasting factors.
Why are geostationary satellites used?
Geostationary communication satellites are used because they are visible from a large area of the Earth's surface which extends 81 degrees in both latitude and longitude. They are directly over the equator. To an observer near the pole, it appears lower in the sky.
What is geostationary transfer orbit?
Geostationary Transfer Orbit is a special case of geocentric orbits which serves as an intermediate orbit for satellites that are destined for Geostationary orbit. It is an elliptical orbit with the perigee as low as the Low earth orbit and apogee as high as geostationary orbit. This is one of the Hohman transfer orbits.
How long does it take for a satellite to return to its orbit?
This implies that the satellite will return to its position after twenty-four hours irrespective of its other properties.
Who invented the geostationary orbit?
The concept of the geostationary orbits was popularized by fiction writer Arthur C. Clarke in the 1940s as a popular way to revolutionize telecommunication. In 1963, the first satellite was placed in a geostationary orbit. The most commonly placed satellites in these geostationary orbits are the communication satellites.
Why is the orbit of a geostationary orbit zero?
Eccentricity of the orbit of the geostationary orbit is zero because of it being completely round and this favors the fact that the satellites are at a fixed radius from the earth which helps in its tracing.
What is a geosynchronous satellite?
What are Geosynchronous Satellites? Ans. A satellite that orbits in the geosynchronous orbit with an orbital period the same as that of the Earth rotation is known as a geosynchronous satellite. The term geosynchronous meaning is that the satellite has the same orbital period as that of the earth's rotation.
What is a Geostationary Satellite?
A geostationary satellite orbits the earth at approximately 35,800 kilometers, or 22,300 miles, over the one longitude at the equator. It revolves in the same direction the earth rotates, west to east. One orbit of a satellite takes 24 hours at this height, the same length as the planet requires to rotate once on its axis.
Pros and Cons of Geostationary Satellites
The geostationary satellite's main advantage is that an earthbound directional antenna can be aimed and left in position without further adjustment. This type of antenna is also much less expensive than a tracking antenna.
Applications of Geostationary Satellite
Geostationary satellites have been used for global communications, television broadcasting, weather forecasting, and defense and intelligence applications. They have been used to monitor fires for over 30 years.

Geostationary Satellite Definition
A geostationary satellite is a satellite that appears stationary when we observe them from the earth. This satellite is placed in a geosynchronous orbit. The geosynchronous orbit is the earth centred orbit that has the same orbital period that the earth takes to complete its rotation on its axis i.e. 24 hours.
Uses
As the geostationary satellite appears to be fixed in a sky i.e. they appear stationary this avoids the use of the moveable antenna. The clients on the earth can install small, cheap and stationary antennas directing towards the desired satellite.
Advantages And Disadvantages
A geostationary satellite makes constantly observe the area covered by the satellite.
