AA 115Q: The Global Positioning System: Where on Earth are We, and What Time is It?
General Education Requirements
Course Description
How do we determine where we are? We will discuss the many kinds of navigation technology, from dead reckoning to sextants to satellite navigation using the Global Positioning System (GPS). Plenty of hands-on experience will be available with sextants and GPS receivers. We will use the GPS receivers to play geo-caching, which is an elaborate GPS/Internet-enabled treasure hunt. Along the way, we will learn how GPS works. More important, we will discover that GPS does not always work, and we will speculate about why, and what could be done to improve its performance.
