History of Satellite Communications The first idea of satellite communication came from an article in 1945 named Wireless World‚ where Author C. Clarke described the use of manned satellites in 24 hour orbits to distribute television programs. However‚ the first person to carefully evaluate the technical and financial aspects of such a venture was John R. Pierce of Bell Telephone Laboratories (Whalen‚ n.d.). In a 1954 speech and 1955 article‚ Pierce described the usefulness of a communications

Satellite imagery The first images from space were taken on the sub-orbital V-2 rocket flight launched by the U.S. on October 24‚ 1946. Satellite imagery consists of images of Earth or other planets collected by artificial satellites. History[edit] The satellite images were made from pixels. The first crude image taken by the satellite Explorer 6 shows a sunlit area of the Central Pacific Ocean and its cloud cover. The photo was taken when the satellite was about 17‚000 mi (27‚000

Artificial satellites are those put into orbit by man. Equipment on a satellite is hardened to survive in the radiation and vacuum of space. Since there is no air in space and therefore no air resistance‚ satellites come in many shapes and sizes. Types of Satellites and their Uses We use satellites for different purposes and all satellites can be placed in one of the following categories: Communications Satellites Distribution of television and audio signals‚ and telephone connections via satellite

Subject : Introduction to satellite (SCM01D4) Introduction Eclipses can only occur when the Sun‚ Earth‚ and Moon are all in a straight line. Solar occur at new moon‚ when the Moon is between the Sun and Earth and in contrast‚ lunar eclipses occur at full moon‚ when Earth is between the Sun and Moon. The apparent size of the Moon is roughly the same as that of the Sun‚ with both being viewed at close

India has launched 74 artificial satellites in space .Here are some of them- Aryabhatta It was indias first satellite.It was launched by the Soviet Union on 19 April 1975[1] from Kapustin Yar using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO) The launch came from an agreement between India and the Soviet Union directed by U.R. Rao and signed in 1972. It allowed the USSR to use India ports for tracking

Satellite Towns In 1927 there were approximately 2 billion people on the earth‚ however today our population is almost 6 billion. This huge amount of increase in human population brought crowded metropolitan areas. In order to create planned cities and houses we created satellite towns. These towns also started to be built in our country. Therefore‚ it might be a good idea to consider its advantages and disadvantages. The main advantage of a town with skyscrapers is its modernity. Since we

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
