My research this year explores the many factors that may limit the accuracy of the Global Positioning System (GPS).  The accuracy of a GPS-enabled device was tested through three main experiments: one experiment investigated the accuracy of an unmoving GPS device as time went on, while the other two tested its accuracy while the device moved at a relatively constant speed.  The accuracy of the device was tested to prove that variation in GPS accuracy can be quantized and possibly predicted based on several factors (such as direction of travel).  My research also examines how improved accuracy of GPS-enabled devices can aid in improving environmental and human safety, based on several articles describing new uses and ideas for GPS technology.
