Advances In Satellite Communication

  1. 1. Govt. Engineering College, Aurangabad Submitted By :-- Rasal Abhijeet Dharmaraj (BE12F04F043) Guided By :-- Jain Ma’am Advances In Satellite Communication
  2. 2. Content • Introduction • Development • Recent Trends
  3. 3. Introduction • A satellite communication is an artificial satellite that relays and amplifies through the use of a transponder between a source and a receiver. • Satellite communication has served mankind in many ways. • Transition from point - point to multipoint - multipoint. • The latest development is the use of networks of small satellites in low earth orbits.
  4. 4. • In this present era, communication plays a vital role. • A satellite receives a microwave signal from a ground station on the earth then amplifies and retransmits the signal back to a receiving station at a different frequency. EARTH Ground Station Transmitting Ground Station receiving Satellite
  5. 5. Development • First communications satellites were designed to operate in a passive mode. • Echo 1 launched by the US in 1960 and Echo 2 in 1964. • Score launched by the US in 1958, was the first active communications satellite.
  6. 6.  Commercial • Foundation of the Communications Satellite Corporation (COMSAT) in 1963. • International Telecommunications Satellite Organization (INTELSAT) was formed in 1964. • Early Bird in 1965. • The first of the Intelsat 4s provided 4,000 voice circuits. • In the early 2000s, INTELSAT had 21 satellites in orbit, providing the world's most extensive telecommunications system.
  7. 7.  Services • Broadcasters use data from meteorological satellites to predict weather and to broadcast storm warnings when necessary. • Collect meteorological and infrared information about the atmosphere and the ocean. • Global village. • Television Infrared Observation Satellite (TIROS) 1 in 1960. • International Mobile Satellite Organization (INMARSAT) in 1979.
  8. 8. Recent Trends • Frequency reuse • Multiple spot beam • Laser beam • Network of small satellite in low orbit.
