    "abstract": "An orbiting `photon clock\u0027 is proposed to test directly the relativity of\nsimultaneity effect of special relativity. This is done by exchanging microwave\nsignals between two satellites in low Earth orbit carrying clocks that have\npreviously been synchronised in the Earth-centered inertial system. A similar\nexperiment using synchronised signals from two GPS satellites with the receiver\non a single satellite in low Earth orbit, is also proposed.",
