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 the definition of satellite communication?
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 at different locations on Earth.
What is satellite and how it works?
A satellite is any object that moves in a curved path around a planet. The moon is Earth’s original, natural satellite, and there are many man-made (artificial) satellites, usually closer to Earth. Sometimes, a satellite’s orbit looks like an ellipse, a squashed circle that moves around two points known as foci.
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.
What are the parts of a satellite?
Parts of a satellite
- The satellite consists of many parts. The main satellite parts which include transponder, antenna subsystems, solar cell, battery backup,camera,thrusters.
- Antenna subsystems:
- Solar cell and battery backup- It keeps satellite running in space.
