GPS (global positioning system) plays a very important role in all of our lives. From allowing you to see where you are on the planet, to helping you get to destinations quickly, GPS has evolved the way in which we live our lives. Find out how GPS works, some of the roles things such as our own atmosphere has in reducing the accuracy of GPS and also how general relativity effects GPS accuracy too.
