Satellites in aerospace engineering
With the advent of mobile communication, the world has come much closer and has become accessible within reach. Across the Americas, Europe and through-out much of the world, digital phones have opened up a new generation of communication.
This has changed the way of how we keep in touch and mobile phones continue to enhance our lives. Today, we not only use mobile technology just to communicate, but it is also being used to transfer data, surf the net, download and play music and various other content applications.
On the hand, it should be noted, that there are several areas in this world, where communication facilities are totally absent. A disaster area may be one such instance where communication is an imperative necessity.
In today’s modern world, we use satellite phone to communicate.
Aerospace engineering defines a satellite is an object which revolves around another object. For example, the Moon is a satellite of the Earth, and the Earth is one of the Sun.
The phenomenon interested mankind to investigate more on this idea and experiment on man-made satellite en-circling the Earth. It was thought that if such a satellite was put in the space, communication could be set up from one part of the world to the other.
A communication satellite orbits around the earth and in effect is an artificial satellite, stationed in space for the purpose of telecommunication.
These satellites use the geosynchronous orbits, Molniya orbits or low polar Earth orbits.
