3 Internet 1 and Internet 2 Earth Satellite Tachyon Central Ground Station San Diego Internet Sites Transportable Ground Station ©2004 Robert S. Dixon. All Rights Reserved.

4 Provide high-speed Internet access for ALL purposes, including computers, telephones and PDAs. Inexpensive to build and operate Off-the-shelf parts for easy duplication Easy to operate by one person with one day training, with NO hand tools. Small and light Reliable and adaptable to diverse field conditions Easily modified Transportable System Design Goals

5 ©2004 Robert S. Dixon. All Rights Reserved. Planned Applications Emergency communications. Provide distance learning in under connected locations such as rural areas and inner cities. Link field research to campus computers and laboratories and collaborators worldwide. Link field instruction and demonstrations to campus classrooms. Link field activities to remote databases, eg via PDAs. Special events, conferences, fairs, etc. Remote monitoring of construction projects.

6 Some Actual Applications Distance Teaching and Learning Conference Madison, Wis. August 2002 Ohio Farm Science Review rural Ohio, Sept 2002 and 2003 National Farm Progress Show rural Iowa, Sept 2002 Distance Learning Conference Worthington, Ohio October 2002 Kentuckyana Cattle Auction rural Kentucky, February 2003 Lewis and Clark Re-enactment Pennsylvania to Oregon and back

9 Reliability of the Satellite Trailer The Lewis and Clark Expedition has used it: Every day for 6 months At over 100 different rural locations Over 3500 miles traveled, including rough roads With NO FAILURES PS - They now set it up in 7 minutes, using 2 people.

10 Satellite Trailer Subsystems Dish and Radio Transceiver Power Leveling and Aiming Heating and Cooling On-Board Computer Local Wired and Wireless Connections Specialized Remote Units Telephone Video Broadcasting and Conferencing ©2004 Robert S. Dixon All Rights Reserved.

11 Ground Station Power Alternatives (ALL are provided) Local Power Outlet unlimited (long extension cord) Batteries via UPS 4 to 8 hours before (computer controlled) recharging Gasoline generator 3 days before (pushbutton start) refueling Type of power Running Time Also provides power to user-supplied equipment. ©2004 Robert S. Dixon All Rights Reserved.

12 Aiming System Satellites are 2 degrees apart in the sky; aiming accuracy must be better than 1/2 degree. GPS Receiver provides accurate local position to PC. (or just use Zip code) PC calculates azimuth, elevation and polarization settings. (or just use provided aiming maps) Dish is aimed with precision compass and inclinometer, using simple adjustments. Azimuth - motor drive Elevation - hand operated turnbuckle NO hand tools required. ©2004 Robert S. Dixon All Rights Reserved.

Automatic thermostatically controlled ventilation fan. No actual air cooling. Use provided parasol if needed. Contents: Radio transmitter and receiver UPS and batteries (more batteries elsewhere) Auditory dish aiming instrument Ethernet switch, DHCP/NAT server Laptop PC Local wireless access point Power line frequency meter

15 Computing System Laptop PC Runs 3 special programs: Satellite aiming Dish Transceiver control and monitoring UPS control and battery monitoring Also supports all Internet access tools such as: Web browsing H.323 Video Conferencing Distance Learning tools optional encryption ©2004 Robert S. Dixon All Rights Reserved.

16 Local Site Transportable Ground Station Long-Range wireless (up to 20 miles) Wall-Penetrating wireless (several non-metal walls) Local Wireless (1000 ft) Local Ethernet Cable (200 ft) Ground Station to Local Site Connection Alternatives (ALL are provided) ©2004 Robert S. Dixon All Rights Reserved. 4

17 Latest State-of-the Art Wireless Antenna Technology To achieve long range, wireless antennas MUST be directional. That requires careful aiming of the antenna at distant user. All distant users must be in the same direction. New phased array antenna: Aiming is done automatically and electrically. No actual physical aiming of the antenna. Covers a full sector all at once. Longer range than ANY other antenna.

18 Specialized Remote Units BoatAutomobile Backpack Equestrian Satellite Trailer (Wearable heads-up display under development)

19 Superimposed Video Information and Event Documentation Time and Date Exact Location Elevation above sea level Speed (if camera is moving) Camera Look Direction Customizable Identification Label Future: Street Address, City, County, State, Zip Code ANY available data as desired, such as: Voting Precinct Insurance Policy Number Soil Type Anything you can think of ©2004 Robert S Dixon.
