Published by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam,...Relativity in the Global Positioning System- January 28, 2003 The Global Positioning System (GPS) uses accurate, stable atomic clocks in satellites and on the ground to provide world-wide position and time determination. These clocks have gravitational and motional frequency shifts which are so large that, without carefully accounting for numerous relativistic effects, the system would not work. This paper discusses the conceptual basis, founded on special and general relativity, for navigation using GPS. Relativistic principles and effects which must be..http://www.livingreviews.org/lrr-2003-1 |
