A New Test of Relativity
Abstract
A new fundamental test of Einstein's theory of special relativity is currently underway, employing instrumentation of the National Aeronautics and Space Administration Deep Space Network (DSN) and the Global Satellite Positioning System (GPS). The scientific objective of this experiment is to search for a possible spatial variation of the one-way velocity of light. The experiment involves monitoring over a full rotation of the Earth the time of flight of laser pulses transmitted along optical fibers connected to hydrogen maser clocks separated by several kilometers. These clocks are additionally compared by radio link using GPS satellites. This unique experimental configuration, coupled with state-of-the-art technology, allows us to test precisely the assumed constancy of the one- way velocity of light.
