Satellite Technology in Practical Business Applications Michael J. O’Donnell MSIT 526
Presentation Outline • History and Development of Satellite Technology • Satellite Operation and Types of Satellites • Satellite Network Topologies • Benefits of Satellites over Terrestrial Networks • Current Satellite Solutions
Arthur C. Clark • “Extra-terrestrial Relays” 1945. • Three 24hr manned Orbiter to distribute television signals.
Dr. Harold Rosen, SYNCOM II • Dr. Harold Rosen
Communication Satellite Act 1962 • Build an international satellite • Resulted in COMSAT in 1965. • Early Bird
INTELSAT IV • 12 transponders vice one • Backbone of international communications
PanAmSat • Mr. Rene Anselmo • 1984-1st privately designed and operated Satellite in U.S.
Orion • 1st to use VSAT for Business Applications • Japan, India, Middle East, and Latin America biggest users of satellite
Motorola’s Iridium Project • 77 LEO satellites, $5 Billion dollars • Chapter 13 after 474 days of service • Bought for $25M
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
Low Earth Orbit (LEO) • Travel at high speeds, circle earth in 90 min.
Medium Earth Orbit (MEO) • Normally for satellites that cover the poles. Placed in an elliptical orbit.
GSO (Best type) • 22,282 miles above earth, same direct and speed of earth, 24 hours trip, View 1/3 of earth
Network Topologies Simplex Duplex Point to Multipoint Mobile Antenna Systems Star Mesh
Simplex • Broadcast transmissions such as TV, video and radio services.
Duplex • Voice Telephony transport • Data and IP transport Corporate networks • TV and Broadcast program contribution and distribution
Point to Multipoint • Corporate networks, including VSAT services and business television. • Video and broadcast distribution, including Direct-to-Home Internet services.
Mobile Antenna Systems • Satellite News Gathering • Special Event Backhaul and Broadcasting • Maritime services
Star Network • Corporate Networks • Distance Learning
Mesh Network • National and International Telephony and Data networks • Rural Telephony
Benefits of Satellites over Terrestial Networks Universal Versatile Reliable Expandable Flexible Availability
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.
Determining Satellite Needs for Your Business Technology Risk Coverage Transmission Quality Satellite Cost
Case Study- AMECO INTELSAT- Top Ten Satellite World Provider Domestic Long-haul Shipping Company Railroad, truck, airlift High data transmission, Inventory Control, Complete Zone area coverage.
Solution- GXB Business Broadband • Broadband Voice, data, and Video • 5.25 Mbps outbound, 2.25 Mbps inbound • Higher throughput compared to competing platforms
Future of Satellite • Government, Military, and Developing Countries • Mobile Satellite Services • BGAN is the future.
