  • Abstract
    Two strontium lattice clocks, one in Japan and the other in Germany were directly compared by a two-way satellite frequency transfer technique that utilizes the carrier phase of the transmitted signal. The comparison has resulted in a fractional difference of 1.1(1.6)×10-15, directly confirming the frequency agreement on an intercontinental scale.
