This document provides an overview of VSAT (Very Small Aperture Terminal) satellite communication technology. It describes how geostationary satellites are used to provide internet, voice, and data services to ships at sea via antennas on the vessels. Benefits of VSAT include always-on connectivity without extra usage fees. Challenges include latency from the long distance to satellites and potential interference issues. The document also outlines services and solutions provided by a specific VSAT network operator.
3. • Geostationary Satellites are Located 22,300 Miles (35,786 km) above
the Earth’s Equator
• Operates on “line of sight” basis
• “Latency” Due to Round Trip Distance to Satellite
– Approximately 500 Millisecond Roundtrip
– Impacts Internet page loading, voice call experience and fax
transmissions
• C-Band: Global Beam, Wide Coverage
– Requires 2.4-meter antenna minimum
– Circular and Linear Polarizations
• Ku-Band: Regional, Limited Coverage
– Requires 1.0-meter antenna minimum
• Coverage Area Is Described as a “Footprint”
– AOR, POR, IOR
– Regional, Spot, Hemi or Global Beams

4. • C-Band: Electromagnetic or Terrestrial Microwave Interference
• Ku-Band: “Rain Fade” in Extreme Weather
– Effects can be mitigated by higher power amplifiers from ship and
increased satellite power
• Military RF Interference
• Physical Blockage
– Buildings, Fjords or Ship Superstructure
• Terrestrial Outages
• Satellite Issues
– Solar Activity or Spacecraft Malfunction
• Ocean Currents should not affect performance due to stabilized
antenna design

sparingly
– Extend data networks to become “floating offices”
– Limit unnecessary travel to ships
– Reporting requirements are increasing

9. Our customers always receive:
• Committed Information Rate with “Burstability”
• CIR establishes bandwidth “floor”
• MIR establishes bandwidth “ceiling”
– We do not “oversubscribe” our network
– We do not sell your bandwidth to multiple other
customers and hope that everyone will not use it at
the same time
– We do not offer a “best efforts” or “contended” network in which
customers must compete with one another for capacity
– Your user experience will not degrade over time
– Burst pools are comprised of unused bandwidth on our network
and satellite inventory

12. • Ku-Band is outpacing demand for C-Band
– Largely due to cost and size
• Smaller and lighter Ku antennas
– 1.5m, 1.2m, 1.15m, 1.0m, 85cm, 60cm
• Multi-band LNBs (Low Noise Block)
– No mechanical intervention required for vessels transitioning
between satellites
• Maritime-specific satellite beams
– New launches in 2009 will greatly expand coverage
• Automatic Beam Switching
– Less intervention from shipboard personnel

14. • New VSAT equipment manufacturers create challenges for VSAT
service providers
• Supply chain
– How many antennas are available?
– Where are they?
• Spare parts
– Spares must be immediately available
• Training
– Are technicians and engineers confident in their ability to install,
troubleshoot and repair?
• Type approval
– Is the antenna compliant?
• Impetus to change
– Is it really a better mousetrap?
