  1. GPS Navigation System October 12, 2010 Timothy Davis Advisor: Frank Hludik

  2. GPS Navigation System • Additional independent study to accompany senior project to include: • In depth explanation of the different aspects of GPS and how they work • Factors that could affect the usability and accuracy of the GPS system The Global Positioning System

  3. GPS Navigation System • Space Segment • 30 satellites that transmit position and time • Satellites are in non-uniform position and time • 6 are visible from any point on earth • Continuously broadcasting messages to GPS receivers on earth Global Positioning System Wikipedia

  4. GPS Navigation System • Control Segment • World-wide • Maintain satellites proper orbit • Upload navigational data to satellites • Monitor health and status of satellites • Adjust Orbit Of Satellites GPS Explained: The Control Segment

  5. GPS Navigation System • User Segment • Most receivers can use at least 12 satellites simultaneously • Receives navigation messages from satellites • Calculates the transmission time of navigation messages • Receivers use data to calculate position, time, speed and direction of travel Global Positioning System Wikipedia

  6. GPS Navigation System • Problem Statement • Design and implement a compact, low power hand held GPS Navigation System for use on the University Of New Hampshire Campus

  7. GPS Navigation System • Design Objectives • Indicate current location on a map of the UNH Campus • Display current date and time • Display the number of satellites it is using to calculate location • Display the speed and direction of travel • Display current altitude • Hand held (small, battery powered)
