    1. 1. A Student should have……???
    2. 2. Confidential <ul><li>A Communication Satellites is an artificial Satellite placed into the space for the purpose of Telecommunication. These Satellites are also used for applications like TV and radio broadcasting. </li></ul>
    3. 3. <ul><li>Introduction </li></ul><ul><li>History </li></ul><ul><li>Major Satellites </li></ul><ul><li>Relevance </li></ul><ul><li>Functioning </li></ul><ul><li>Different orbits </li></ul><ul><li>GPS </li></ul><ul><li>Applications </li></ul>Confidential
    4. 4. <ul><li>Satellite is any object that revolve around a very huge object. </li></ul><ul><li>For example:- </li></ul><ul><li>Moon is a satellite of the Earth. </li></ul><ul><li>Earth is a satellite of the Sun. </li></ul>Confidential
    5. 5. <ul><li>The first artificial satellite was launched in 1957 by UK. </li></ul><ul><li>&quot;Artificially, any object placed into orbit around Earth, planets or the Sun to serve a specific task. </li></ul>Confidential
    6. 6. Confidential Satellites Details Year Herman Potocnik Describes Base Station. 1928 Arther C. Clarke First Geosynchronous orbit for communication. 1945 Sputnik-1 First satellite equipped by radio - transmitters . 1957 Project SCORE America's first communications satellite. 1958 Echo First passive reflector satellite. 1960 Molniya First Soviet communication satellite with highly elliptic orbit. 1965 Oscar-III First amateur radio communications satellite. 1965
    7. 7. <ul><li>Engineers have developed many kinds of satellites. </li></ul><ul><li>Each Satellite has been design to serve a specific task. </li></ul><ul><li>Like Telecommunication, broadcasting, Remote Sensing and whether forecasting etc. </li></ul>Confidential
    8. 8. <ul><li> Till now thousands of these &quot;man-made moons&quot; have been rocketed into Earth orbit. Artificial satellites play key role in the communication, industry, military intelligence and in the scientific study of both Earth and outer space. </li></ul>Confidential
    9. 9. <ul><li>Low Earth Orbit. </li></ul><ul><li>Mid Earth Orbit. </li></ul><ul><li>Highly Elliptical Orbit. </li></ul><ul><li>Geosynchronous Orbit. </li></ul><ul><li>Polar Orbit. </li></ul><ul><li>Molniya orbit. </li></ul>Confidential
    10. 10. <ul><li>A Geostationary appear to be fixed when observed from the earth. </li></ul><ul><li>Ht=34,000km </li></ul><ul><li>The orbiting time of Satellite and the rotating time of the earth are equal. </li></ul><ul><li>These are preferred for TV and radio Broadcasting, Remote Sensing </li></ul>Confidential
    11. 11. <ul><li>This Satellite Revolves around earth in a typical circular orbit. </li></ul><ul><li>Ht= 200-1000km </li></ul><ul><li>Time period=90-120 min </li></ul><ul><li>Preferred in whether forecasting, telemetry and tracking. </li></ul>Confidential
    12. 12. <ul><li> These satellites have high latitudes and appears to be geostationary in the lower horizon. </li></ul><ul><li> It Works in a elliptical orbit having earth’s centre at its one foci. </li></ul><ul><li>For telephony and Radio systems. </li></ul>Confidential

    17. 17. <ul><li>The GPS is divided into three major components :- </li></ul><ul><li>1)The Control Segment </li></ul><ul><li>2)The Space Segments </li></ul><ul><li>3)The User Segment </li></ul>Confidential
    18. 18. <ul><li>The Control Segment consists of five monitoring stations (Colorado, Ascension Island, Diego, Hawaii, and Kwajalein Island). Three of the stations (Ascension, Diego Garcia, and Kwajalein) serve as uplink installations, capable of transmitting data to the satellites. </li></ul>Confidential
    19. 19. <ul><li>The Space Segment consists of the Constellation of NAVASTAR earth orbiting satellites. The current Defense Department plan calls for a full constellation of 24 . The satellites are arrayed in 6 orbital planes, inclined 55 degrees to the equator. They orbit at altitudes of about 12000, miles each </li></ul>Confidential
    20. 20. <ul><li>The user segment is a total user and supplier community, both civilian and military. The User Segment consists of all earth-based GPS receivers. Receivers vary greatly in size and complexity, though the basic design is rather simple. The typical receiver is composed of an antenna and preamplifier, radio signal microprocessor, control and display device, data recording and power supply. </li></ul>Confidential
    21. 21. <ul><li>GPS is made up from 3 different components. The first segment of the system consists of 24 satellites, orbiting 20,000 km above the Earth.This means that it takes each satellite 12 hours to make a complete circle around the Earth. The satellites are divided into six groups of four. Each group is assigned a different path to follow. This creates six orbital planes which completely surround the Earth. </li></ul>Confidential
    22. 22. <ul><li>Telephony </li></ul><ul><li>Satellite television </li></ul><ul><li>Fixed Service Satellite </li></ul><ul><li>Direct broadcast </li></ul><ul><li>Mobile satellite </li></ul><ul><li>Satellite radio </li></ul><ul><li>Amateur radio </li></ul><ul><li>Satellite Internet </li></ul><ul><li>Military uses </li></ul>Confidential
