equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth with respect to the stars‚ or 23 hours 56 minutes 4.1 seconds‚ and thus by Kepler’s third law the orbital radius is 42‚164 km. Taking into account the radius of the earth‚ the height of a satellite above the equator is 35‚786 km. Clarke observed that only three satellites would be required to provide communications

infared satellite. I say this because it is looking underground‚ even if it is just a foot‚ and seeing things that you wouldn’t be able to see with just your eye. These Egyptologists‚ are taking these devices and looking at different denser areas in the ground to find out if there was once a city‚ tomb‚ or road there. "If I had approched this as a traditional foot survey‚ it would have taken me three and a half years" (Article 3‚ Paragraph 5)‚ this shows how effective the infared satellite is.

Whatever the mission‚ be it manned or unmanned‚ for scientific research‚ applications or space transportation‚ a spacecraft must withstand the extreme stresses which occur during the launch phase‚ and once in orbit‚ the rigours of the space environment. There is one way of making sure of this: to test the spacecraft on Earth under conditions simulating‚ as closely as possible‚ those it will meet during the launch and its orbital life. This can be done with with tests which demonstrate by application

of satellite communication systems have been proposed using geosynchronous (GEO) satellites‚ as well as low earth orbit (LEO) constellations operating in the Ka-band and above. At these frequencies satellite networks are able to provide broadband services requiring wider bandwidth than the current services at C or Ku-band. As a consequence‚ some of the new services gaining momentum include mobile services‚ private intranets and high data rate internet access carried over integrated satellite-fiber

The Future of Satellite Internet: For many people throughout the world‚ the only way to get online is by using satellite internet service. This is because they live in regions where traditional cable or DSL lines are not there. This may be because of landscape or the fact that some homes and businesses are simply located too far into rural regions and it is not cost effect for traditional companies to run lines to only one or two clients. However‚ a satellite internet connection does not rely
