Satellites have silver plates that recharge the power source stored in batteries. Some satellite uses fuel energy that changes compound energy into electricity. There are satellites that run on nuclear energy. Miniature propellers offer outlook, elevation, as well as forward motion parameters to develop and alleviate the satellite's site in space. To supplement climate monopoly onboard, energy is needed. Specialized configurations accomplish the errands dispersed to the satellite. These mostly incorporate sensors competent of photographing a variety of signal lengths. Whereas ecological satellite demands optics, telecommunications satellites don't. Ecological satellite remits statistics in binary format on a computer that translates the same numbers into geometric images. Gerven S.V and Compernolle D.V (2000)

Introduction

Communication satellite is a radio transmitter antenna that orbits above the earth that receives, intensifies, and prejudices analog and digital indications carried on unambiguous radio regularity.

Summary

Satellite launching is rather a ubiquitous phenomenon that has evolved from halting the country's commerce to warranting that if functions like clockwork. Like any other scientific advances the reminiscent of computers, clocks and phones, the satellite has advanced to become one of the most reliable technology through which information is relayed .Satellites dole out elementarily for map-reading, connections, backdrop scrutiny as well as climate forecasting…
