1 December 4, 2009 Calvin College ENGR 339 Senior Design

2  The Team  Problem & Solution Recap  Feasibility  Design Norms  Resources  Major Achievements  Current Status  Next Steps  Questions

3 DaveAnthonyAndrewDanny MoelkerBoorsmaHoogendamVanderspek

4  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

5 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

6  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 3 1.http://www.nature.nps.gov/stats/viewReport.cfm?selectedReport=SystemMultiReport.cfm 2.http://www.activemarketinggroup.com 3.http://www.canalys.com/pr/2008/r htm

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

8  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

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

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

11  Digitally communicate between the microcontroller and accelerometers  Microcontroller stores the data  Transfer data to a PC for algorithm testing and development

12  Further development of data acquisition platform  Build the algorithms for filtering the noisy data from the sensors  PPFS Revisions

13  Add gyroscopes into the data acquisition platform  Printed circuit board layout  Purchase components  Develop the algorithms to convert sensor readings to positions accurately
