    Satellite technology has advanced dramatically since the launching of the first artificial satellite, Sputnik, in 1957. There are hundreds of satellites orbiting Earth right now, launched and funded by many different nations (the US included). They are used for things like GPS or cellular communication, but also for measuring different aspects of our planet. Satellites’ ability to see into different sections of the light spectrum enable them to collect data better and more efficiently than ever before

    Satellites A satellite is defined as an object that orbits or revolves around another object.  In basic terms, this relationship is due to the gravitational pull of the larger object while the smaller one has enough velocity and momentum to circle the larger one (Fitzgerald &Dennis).  This is a good definition if one is only speaking of the broad principles of why and how objects attract one another and where in nature this occurs.  The billions of stars and planets together make up a vast network

    Satellites orbit the earth doing our bidding in ways that enrich the lives of almost all of us. Through electronic eyes from hundreds of miles overhead, they lead prospectors to mineral deposits invisble on earth's surface. Relaying communications at the speed of light, they shrink the planet until its most distant people are only a split second apart. They beam world weather to our living room TV and guide ships through storms. Swooping low over areas of possible hostility, spies in the

  • Satellite Broadband

    communication satellites are beginning to emerge as an attractive solution in providing broadband connectivity to a variety of users. The wide area or global coverage of satellites enables service provision to a large number of dispersed users and solve the expensive "last-mile" issue without dedicating to each user cable, fiber, switching equipment ports, etc. The broadcast nature of satellites supports efficiently the transmission of the same message to a large number of stations, making satellites the natural

    Works Cited Incomplete Sputnik: The Satellite That Inspired Generations Introduction In 1950, a group of American and European scientists decided to establish a worldwide program to promote research and understanding of the world around them. They decided that July 1957 to December 1958 would be called the International Geophysical Year, or IGY. They hoped that drawing attention to geophysical matters would stimulate new projects and inventions, and increase the knowledge the world had of

    Satellites Satellite is probably the most useful invention since the wheel. Satellites have the capability to let you talk with someone across the nation or let you close a business deal through video communication. Almost everything today is heading towards the use of satellites, such as telephones. At&t has used this communications satellite (top right) ever since the late 1950s. TVS and radios are also turning to the use of satellites. RCA and Sony have released satellite dishes for Radio and

    Communication Satellites Have you ever thought about how that little phone in your hand works? What about how you always seem to have internet and cable access? A satellite is a device put into orbit around Earth that uses receivers, amplifiers, and transmitters to receive and send signals around the globe (“Communications Satellite Aug. 2007”). Satellites provide the signals to these and more devices. Satellites orbit Earth and provide global communications, as well as collect valuable data. Many

    Satellite Surveillance I. Preface My interest in satellite surveillance did not really appear to after I saw the movie "Enemy of the State" in 1998. The synopsis of the movie is: Robert Dean (Will Smith) is a labor lawyer who is unknowingly in possession of evidence related to a serious politically motivated crime. Government agents eager to hide their guilt believe that Dean is on to them, and proceed to turn his life upside-down, ruin his reputation, and frame him for various incidents, thanks

    B. Satellites for navigation Satellites provide the necessary information to the navigation system to measure vehicles location. There are about 31 active satellites used for GPS communication, which are rotating around the earth’s axis. Their orbit is inclined 55 degrees with respect to the equator. Satellites are placed at 20,000 km from the earth’s surface. The orbits are designed in such a way that each satellite rotates two orbits per day. Orbits are planned so that at least 6 satellites in
