A satellite is a body that moves around another body in a mathematically predictable path called an Orbit.
A communication satellite is nothing but a microwave repeater station in space that is helpful in telecommunications, radio, and television along with internet applications.
What is the principle of satellite?
The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity.
What is meant by satellite communication?
Communications satellites are commonly used for mobile phone signals, weather tracking, or broadcasting television programs. Communications satellites are artificial satellites that relay receive signals from an earth station and then retransmits the signal to other earth stations.
What is the role of satellite in communication?
Communications satellites are used for television, telephone, radio, internet, and military applications. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.
What is satellite communication and how does it work?
A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver(s) at different locations on Earth. Wireless communication uses electromagnetic waves to carry signals.
What are the 4 types of satellites?
Types of Satellites and Applications
- Communications Satellite.
- Remote Sensing Satellite.
- Navigation Satellite.
- Geocentric Orbit type staellies – LEO, MEO, HEO.
- Global Positioning System (GPS)
- Geostationary Satellites (GEOs)
- Drone Satellite.
- Ground Satellite.
What are 3 uses of satellites?
Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and space telescopes. Space stations and human spacecraft in orbit are also satellites.
What are the elements of satellite communication?
The satellite itself is also known as the space segment, and is composed of three separate units, namely the fuel system, the satellite and telemetry controls, and the transponder.
What are the components of satellite communication?
Satellite communication has two main components: the ground segment, which consists of fixed or mobile transmission, reception, and ancillary equipment, and the space segment, which primarily is the satellite itself.
What are the advantages of satellite communication?
Customers in rural and remote regions around the world who cannot obtain high speed Internet access from a terrestrial provider are increasingly relying on satellite communications. Superior Reliability – Satellite communications can operate independently from terrestrial infrastructure.
What is the importance of satellite?
The bird’s-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground. Satellites also can see into space better than telescopes at Earth’s surface.
Which frequency is used in satellite communication?
Used for satellite communications. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra.
What is the main purpose of a satellite?
Most artificial satellites orbit Earth. People use them to study the universe, help forecast the weather, transfer telephone calls over the oceans, assist in the navigation of ships and aircraft, monitor crops and other resources, and support military activities.
