Introduction
The goal of this project was to design a GPS device capable of outputting
 directions via interstates to any major city in the continental United States.
  The device was designed to interface with any GPS receiver capable of 
outputting NMEA v0183 RMC sentences via RS232 connection.  Our 
motivation behind this project was to create an expandable design capable
 of using a larger database of cities and connecting roads.  The device was
 programmed with a small database consisting of major cities and connecting
 interstates.  Please see below map of cities and connections included in our
 database.  This database is used to map out directions between any two 
major cities in the database.  This design could easily be expanded and made
 portable for use in automobiles or other vehicles.  This project was intended
 to demonstrate some ideas that could be used to create a commercially 
available Global Positioning Device.
