here some of the concepts are given below .
There are many kinds of satellites and many ways of building a satellite. Most satellites have similar parts, however. These parts include
(1) radios to talk to people on earth;
(2) rockets to move the satellite in space;
(3) batteries to supply energy; and
(4) computers to control the satellite. Some satellites also have cameras to take pictures from space

DIFFERENT PARTS

• Antennas and transceivers send and receive radio signals to and from the Earth or another satellite;
• Rocket motors move the satellite in space;
• Fuel tanks store the fuel for the rocket;
• Solar panels use solar cells to turn the sun's energy into electricity;
• Batteries store the electricity generated by the solar panels; and.
• On-board processors provide the “brain” of the satellite and tell the satellite to do what humans want it to do

ENGIEWS


- PROGRESS TOWARDS SUCCESS



VISION:

“To express ourselves (thoughts, views, opinions etc) independently that lead us in the right direction towards success.!!!”



We are happy to inform you all that we started a blog in the name ENGIEWS (http://engiews.blogspot.com).

It is for all those guys (peoples) who are interested in joining this blog and utilize their time effectively as well as fruitfully.



We began this blog considering this thought,

“A man of ordinary talent will always be ordinary whether he travels or not…

But a man of superior talent will go into pieces if he stays forever in the same place…”



Since we(especially YOUTHS) are of superior talent with extraordinary potential, we are capable of expressing our views independently that would take us at least one step forward in the progress and development of ourselves at first, then our society and finally our nation, INDIA.



This blog mainly helps us to share our views, thoughts, opinions, queries and discussions of all subjects(including education, technology, economics, social activities, politics, entertainment, sports etc) at all levels put to good cause and effect.



“If you want something which you never had before , Do something which you have never done before…”



Therefore , we request all of you to join us with great enthusiasm and commitment. You are free to participate and contribute your own views, thoughts and experiences for this good cause to a great extent..!!!
