Abstract
The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degrees of freedom two-way laser link between remote spacecraft succeeded on the first attempt. Active beam pointing based on differential wave front sensing compensates spacecraft attitude fluctuations. The LRI has operated continuously without breaks in phase tracking for more than 50 days, and has shown biased range measurements similar to the primary ranging instrument based on microwaves, but with much less noise at a level of 1 nm/Hz at Fourier frequencies above 100 mHz.

N1 - Funding information: The LRI team would like to acknowledge the GRACE Follow-On Project teams at JPL including project management, mission assurance and quality assurance, project and flight system engineering, mission operations and science data systems at JPL and CSR. It is a pleasure to acknowledge the spacecraft provider, Airbus Defence and Space, for their excellence in integrating the LRI instrument to precise requirements without which the LRI could not meet its goals. The LRI team would like to acknowledge the Deutsches Zentrum für Luft und Raumfahrt (DLR) and German Research Centre for Geosciences (GFZ) Mission Operation teams at the German Space Operation Center (GSOC) for their excellent work and support in commanding the LRI instrument in all mission phases. The Australian National University developed an alternative triple mirror assembly and were involved in testing and concept development for link acquisition. Part of the research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration. GRACE-FO is a partnership between NASA and German Research Centre for Geosciences in Potsdam, Germany. JPL manages the mission for NASA’s Science Mission Directorate. The development of the LRI in Germany was supported by Bundesministerium für Bildung und Forschung (BMBF), Project No. 03F0654B, Deutsche Forschungsgemeinschaft (DFG) and Deutsches Zentrum für Luft- und Raumfahrt (DLR).
