Absolute frequency readout derived from ULE cavity for next generation geodesy missions

Rees, Emily Rose; Wade, Andrew; Sutton, Andrew; Spero, Robert; Shaddock, Daniel; McKenzie, Kirk


The next generation of Gravity Recovery and Climate Experiment (GRACE)-like dual-satellite geodesy missions proposals will rely on inter-spacecraft laser interferometry as the primary instrument to recover geodesy signals. Laser frequency stability is one of the main limits of this measurement and is important at two distinct timescales: short timescales over 10-1000 seconds to measure the local gravity below the satellites, and at the month to year timescales, where the subsequent gravity...[Show more]
