WebThe global positioning system (GPS) provides a superb opportunity to introduce relativity concepts to undergraduate students, including non-physics majors. Familiarity with the numerous applications of GPS motivates students to understand relativity. A few fundamental principles need to be introduced, including the postulates of special relativity WebJul 18, 2006 · earth or comparing clocks that are thousands of km apart on earth’s surface but that have one or more GPS satellites in view at the same time. The relativity of simultaneity, the constancy of c, and the first-order Doppler effect are intimately related. In the next section, three important relativity principles are described.
