1.Weather monitoring.2.Communication,3 Education, 4.Research and 5.Defence purpose.Details of each use is obtained in any book of class ten science ( in chapter of space ).

Answer 2

Artificial satellite is an object constructed by humans and placed in orbit around the earth or other celestial body (see also space probe). The satellite is lifted from the earth's surface by a rocket and, once placed in orbit, maintains its motion without further rocket propulsion. The first artificial satellite, Sputnik I, was launched on Oct. 4, 1957, by the USSR; a test payload of a radio beacon and a thermometer demonstrated the feasibility of orbiting a satellite. The first U.S. satellite, Explorer I, launched on Jan. 31, 1958, returned data that was instrumental in the discovery of the Van Allen radiation belts. During the first decade of space exploration, all of the satellites were launched from either the United States or USSR. Today, there are more than three dozen launch sites in use or under construction in more than a dozen countries.
» Artificial satellites are used to transmit TV pictures and telephone calls, for navigation (the Global Positioning System - GPS) and for observation such as weather forecasting, map making, taking pictures of stars and planets and spying.
» Geostationary satellites orbit the Earth every 24 hours so remain over the same point on Earth.
Since the invention of satellites, there have been many changes. These new uses have been made possible due to the channeling of ideas between organizations and countries. They have become essential to people in almost all countries around the world.
Satellites of 1960's:
During the 1960's satellite use began to flourish for the regular use of humans. In August 1960, the United States launched Echo I; this satellite reflected radio signals to Earth making satellite communication possible. Also in April in 1960, Tiros I was sent out to space. Tiros was the first weather satellite that sent pictures of clouds to Earth. The U.S. navy developed the first navigation satellite, the Transit IB navigation satellite which first orbited in April 1960. By 1965 more than 100 satellites were being placed in orbit each year.

Satellites of 1970's:
During the 1970's there was innovation in the satellite world. New and more effective satellite instruments were being used. They have made use of computers and miniature electronic technology in satellite design and construction.
Satellites of 1980's:
During the 1980's satellites were used to save people and other satellites. The first satellite salvaging operation took place in November of 1982, when the Palapa B-2 satellite was coaxed into Challenger's (another satellite) cargo hold by space walking astronauts.

Satellites of 1990's:
The uses of satellites in the 1990's rapidly grew for common, everyday tasks. For example an independent company TRW Inc. planned to create a satellite system that would dominate the satellite communications network. This system called Odessey would be used for the phone business. TRW's satellites would focus on populated areas, as it would cover the Earth uniformly. According to Coy "the company hoped to build a cost effective lucrative entry into the potentially explosive satellite phone business". These innovations have been getting better each day.

Conclusion:
For years to come, we the people will continue to innovate throughout the 21st century. With the development going the way it is the satellite industry will be productive for years to come.

Answer 3

artificial satelite>>> satelites made by man which is sent in space in their specific orbital to perform some function like weather forecasting,transmission of waves like tv signal,mobile etc.
many satelliite have different function like hubble space is used as telescope.
mainly their are 2 types of atificial satellite 1> polar
2>equatriol
due to their position of oribital

Answer 4

They bounce signals of them around the world to other towers to transmitt signals over long distances. Spys bounce them off a number of satellities and towers in other countries to throw off the trace. the moon can be used as a satellite to bounce signals off

Answer 5

artificial satellites? You mean those in outer space? I believe it is used to provide worldwide coverage e.g. Cable connection in your home.

Answer 6

well you are asking this question online only bcoz of the presence of artificial satellites

Answer 7

mostly the articifial satellites are used in the communication.

Answer 8

they are used for telling the weather, taking pictures of the world, for TV pictures and sound, mobile and home phone signals
