  3. Arthur C. Clark • “Extra-terrestrial Relays” 1945. • Three 24hr manned Orbiter to distribute television signals.

  4. Dr. Harold Rosen, SYNCOM II • Dr. Harold Rosen

  5. Communication Satellite Act 1962 • Build an international satellite • Resulted in COMSAT in 1965. • Early Bird

  6. INTELSAT IV • 12 transponders vice one • Backbone of international communications

  7. PanAmSat • Mr. Rene Anselmo • 1984-1st privately designed and operated Satellite in U.S.

  8. Orion • 1st to use VSAT for Business Applications • Japan, India, Middle East, and Latin America biggest users of satellite

  9. Motorola’s Iridium Project • 77 LEO satellites, $5 Billion dollars • Chapter 13 after 474 days of service • Bought for $25M

  10. INMARSAT’s BGAN • Leading Provider of Mobile Satellite Services • Next generation of satellite voice, video, and data communicate • http://broadband.inmarsat.com/about/BGAN_video.aspx?language=EN&textonly=False

  11. Satellite Operation

  12. Low Earth Orbit (LEO) • Travel at high speeds, circle earth in 90 min.

  13. Medium Earth Orbit (MEO) • Normally for satellites that cover the poles. Placed in an elliptical orbit.

  14. GSO (Best type) • 22,282 miles above earth, same direct and speed of earth, 24 hours trip, View 1/3 of earth

  15. BGAN Footprint

  16. Network Topologies Simplex Duplex Point to Multipoint Mobile Antenna Systems Star Mesh

  17. Simplex • Broadcast transmissions such as TV, video and radio services.

  18. Duplex • Voice Telephony transport • Data and IP transport Corporate networks • TV and Broadcast program contribution and distribution

  19. Point to Multipoint • Corporate networks, including VSAT services and business television. • Video and broadcast distribution, including Direct-to-Home Internet services.

  20. Mobile Antenna Systems • Satellite News Gathering • Special Event Backhaul and Broadcasting • Maritime services

  21. Star Network • Corporate Networks • Distance Learning

  22. Mesh Network • National and International Telephony and Data networks • Rural Telephony

  23. Benefits of Satellites over Terrestial Networks Universal Versatile Reliable Expandable Flexible Availability

  24. Satellite Problems and Solutions Echo Problems- Fixed using echo cancelers Transmission Delay Problems: ALOHA protocol Delay Control Unit (Spoofing) Cyclic Redundancy Check Still need Line of Sight Solar Cycles and Heavy weather conditions still adversely affect performance.

  25. Determining Satellite Needs for Your Business Technology Risk Coverage Transmission Quality Satellite Cost
