Optical Time Distributor and Process for Optical Two-Way Time-Frequency Transfer

NIST Inventors
Laura Sinclair , William C. Swann and JD Deschenes
The invention is a method to compare and synchronize "clocks" (i.e., local timescales) through optical links across free space, which include open-air paths through the atmosphere to other terrestrial sites or to satellites, as well as satellite-to-satellite paths. The challenge is to compare the
