Slide__XoNycKOdEd-WfYQ0GneCwQ_subTitle=The less the gravitational field acting on clocks, the faster they run. Using the uncorrected onboard time of a satellite at 20 kilometres height above sea level would lead navigation on Earth astray by about 12 kilometres a day. <p></p> <p>This effect of General Relativity is clearly stronger than that of Special Relativity, and it acts in the opposite direction.</p> <p>For the Global Positioning System (GPS), the total relativistic error amounts to about 10 kilometres per day. This error is corrected by the GPS receiver.</p>
