  21. 21. GPSDoesn’t Work Indoors – does it?<br />“GPS tracking dot”<br />“It’s accurate within two feet anywhere on the globe”<br />
  22. 22. GPSHigh Precision – Too Expensive?<br />
  23. 23. What are the Challenges?<br />New applications<br />Seamless indoor-outdoor personal navigation<br />Intelligent Transport Systems<br />Rail signalling<br />Precision aircraft landing<br />Ships in harbours<br />Location-dependent billing and virtual security fences<br />Tracking people/animals/assets<br />Social inclusion<br />Creates new challenges<br />New technology<br />More GNSS satellites<br />More GNSS signals<br />Communications<br />WiFi / RFID<br />UWB, Sparse Band<br />Digital broadcasting<br />Smaller, cheaper inertial sensors<br />New mapping (outdoor & indoor)<br />More processing power<br />Drives new applications<br />
  24. 24. Multi-sensor Approach<br />GNSS<br />Dead-reckoning sensors<br /> Different technologies solve different parts of the positioning problem<br /> More information enables greater integrity<br /> Diverse technology gives better availability<br />Positioning<br />Terrestrial radio navigation<br />Feature-matching sensors<br />Mapping<br />Communi-cations<br />
