  1. GPS

  2. Physics of GPS

  3. Newton's First Law • An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

  4. Gravitational force • Gravity is continually pulling the satellites down around the earth • The satellites are in a constant free falling state

  5. Electromagnetic waves • Electromagnetic waves do not need a medium to travel through, allowing them to move in a vacuum • This makes these waves perfect for sending data to and from space

  6. Commercial Application

  7. EASE • $109.95 • 3.5” screen • Maps of U.S. and Canada • Announces Street Names

  8. 340S and 540S • 4.3” screen for $139.95 • 5” screen for $159.95 • Maps of U.S., Canada and Mexico • Advanced lane guidance

  9. 350TM and 550TM • 4.3” for $169.95 • 5” for $199.95 • Lifetime traffic and map updates • Superior driving intelligence

  10. Choose your own design!Flags, sports, nature, and other designs also available.You can even upload your own!

  11. Mmm! Guide you there, I will! • $12.95 – Celebrity voice cards • Vader • Homer Simpson • John Cleese • Mr. T • Others

  12. Anecdotal Materials GPS

  13. The Three Satellite

  14. NAVTOOLS ROUTE is a complete route planning application. Unlike any other similar application. NavTools Route is able to calculate the most economical engine rpm setting to reach your destination on schedule, taking into account average or predicted weather along the route (data will include wind speed and direction as well as wave heights and current). Many handy tools are included.

  15. The History Of GPS

  16. Beginnings in WWII • LORAN and Decca Navigator • Used to guide ships away from shorelines • Heavily used by the Navy during WWII

  17. Developments in the 60’s • Transit and Timation Systems • Transit is the first satellite navigation system also used by the Navy • US Navy develops Timation satellite that proved the ability to put accurate clocks into space • GPS relies on this technology

  18. Movement toward GPS • Cold Arms Race helped justify spending the money for research and development of GPS • US Navy and Airforce jointly work together on their missile systems • Enabled them to pinpoint their location prior to launch • 1973 military officials at the pentagon agree on a single superior system Navstar, later known as GPS

  19. The Endless Uses of GPSand the Future
