  1. GPS and Cell Phone Technology FRS 142 The Science and Application of GPS Professor Edward Groth Jonathan Nussbaum

  2. How Cell Phones Can Improve GPS • DGPS Coverage • Receiver Technology • Marketability

  3. DGPS Coverage • Current DGPS Coverage for the U.S. and Canada: • Detailed View: West CoastEast Coast

  4. DGPS Coverage • DGPS range can extend to 250 miles. • However, conditions often limit it to as small a range as 25 miles • What could boost this coverage?

  5. DGPS Coverage • Cingular

  6. DGPS Coverage • Verizon

  7. DGPS Coverage • Sprint

  8. DGPS Coverage • DGPS stations can be relatively inexpensive at low power

  9. DGPS Coverage • Are the benefits worth the cost? • Yes: • Extra coverage in rural areas • New towers not needed • High power DGPS could penetrate buildings • Cell companies could cut deal with GPS or Government • Coverage discrepancies worse in other countries • No: • Non-populated areas still not covered • Cell companies may not be compensated • Planned DGPS expansion

  10. Receiver Technology • Three Aspects that make an Impact: 1. Handheld Technologies: • Smaller Screens • Touch Pads • Full Keyboards • Long Lasting Batteries

  11. Receiver Technology • 2. Internet Connections • Regular Updates • Streaming video • 3. Power • Longer lasting batteries • Easy to use chargers • Power Conservation Modes

  12. Receiver Technology • What does this mean? • Longer lasting • Easier to use and read • Updated map access • Real time plotting

  13. Receiver Technology • Potential Problems: • Strain on batteries • Cost of Service & Roaming • Larger receivers • Solutions: • Subscription to offset cost • Subscription to most used network

  14. Marketability – The Cell Phone Phenomena • Make the GPS receiver essential: • Urban • Suburban • Rural

  15. Cell Phone Technology • GPS easier to use, with more features • Real time maps and photos of the area • DGPS Coverage anywhere • A potential “ground constellation” • GPS Service Indoors, in the City
