This letter, which appears as both a Web article and in a printable version, is part of a series written by a glacial geologist working in Antarctica. In her letters home, Stephanie Shipp shares her work and discoveries. This letter discusses how the compass and other navigation tools helped spur the exploration age, the many changes that navigation technology has gone through since then, the problems inherent in using many of these tools for navigating in and around Antarctica, and the many advantages offered today by the Global Positioning System (GPS). It also explains how the GPS works.
