How Cell Phones Can Improve GPS
  • DGPS Coverage
  • Receiver Technology
  • Marketability
dgps coverage
DGPS Coverage
  • Current DGPS Coverage for the U.S. and Canada:
  • Detailed View: West CoastEast Coast

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?

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

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
receiver technology
Receiver Technology
  • Three Aspects that make an Impact:

1. Handheld Technologies:

        • Smaller Screens
        • Touch Pads
        • Full Keyboards
        • Long Lasting Batteries

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

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

Receiver Technology
  • Potential Problems:
      • Strain on batteries
      • Cost of Service & Roaming
      • Larger receivers
  • Solutions:
      • Subscription to offset cost
      • Subscription to most used network
marketability the cell phone phenomena
Marketability – The Cell Phone Phenomena
  • Make the GPS receiver essential:
    • Urban
    • Suburban
    • Rural

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
