Team Ten, comprised of four engineering students in the Electrical & Computer Engineering concentration, is designing a navigational device that can be carried by a person on an excursion where traditional GPS signals are not available, such as in mountains or caves. This device will track an individual's path and will help the user retrace that path if he or she becomes lost. The end product will primarily use an inertial navigation system for tracking one's position, but will also include a GPS for informational coordinate updates. The device will be battery-powered and will not limit the typical duration of a long excursion. Its weight will be light enough to avoid excessive strain on the carrier, yet also durable enough to withstand the high-impact forces of the wilderness environment. The project will require a systems approach to engineering hardware and software to achieve the end design.
