 Two main methods for hiker navigation:  Compass & Map  Handheld GPS  Both of these have their limitations  There are few devices which successfully overcome these limitations  Individuals get lost

Processor GPS Receiver LCD UI Sensors Accelerometer Gyroscope Memory  A handheld navigation device that does not require a GPS signal to determine position  Use inertial navigation techniques  The user will not become lost

 Average of 1.7 million “backcountry campers” in US National Parks every year over the last 5 years. 1  “More than 20% of the 93 million Americans who participate in hiking, backpacking, mountain climbing, and camping are enthusiasts who participate frequently.” 2  Over 3.7 million personal navigation units sold in Q in the United States

 Patent Research: Honeywell  Competition: American GNC’s Palm Navigator series  Sensor advancements geared toward consumer electronics

 Transparency  Report critical information to the user  Acknowledge limits of the design  Trust  Be reliable and accurate enough to be trusted  Caring  Save lives by preventing individuals from getting lost  Cultural Appropriateness  Appeal to outdoor enthusiasts

 Project from ENGR Control Systems  Project from ENGR Computer Architecture  DornerWorks  Component Suppliers  Mr. Ryan Rooks - HPERDS department  Mr. Tim Theriault - GE Aviation

 Electronic component selection  Obtained evaluation board  Obtained accelerometers and gyroscopes  PPFS rough draft  Constructed a platform for data acquisition
