Handheld Technologies:–Smaller Screens–Touch Pads–Full Keyboards–Long Lasting BatteriesReceiver TechnologyReceiver Technology–2. Internet Connections–Regular Updates–Streaming video–3. Power–Longer lasting batteries–Easy to use chargers–Power Conservation ModesReceiver TechnologyReceiver Technology•What does this mean?•Longer lasting•Easier to use and read•Updated map access•Real time plottingReceiver TechnologyReceiver Technology•Potential Problems:•Strain on batteries•Cost of Service & Roaming•Larger receivers•Solutions:•Subscription to offset cost•Subscription to most used networkMarketability – The Cell Phone Marketability – The Cell Phone PhenomenaPhenomena•Make the GPS receiver essential:–Urban –Suburban–RuralCell Phone TechnologyCell 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
