After fixing an individual's location relative to a network of G.P.S. satellites orbiting 12,000 miles above the earth -- or, more crudely, by the time it takes signals to bounce off nearby cell towers -- personal locator services transmit the constantly updated information to a central database, where customers can retrieve it through the Internet, telephone or pager.
