FREQUENCY AND TIMING ACTIVITIES A REVIEW OF THE JET PROPULSION LABORATORY

L. Maleki, P.F. Kuhnle

Abstract:	The Jet Propulsion Laboratory is the NASA Lead Center for research, development, implementation, and testing of frequency and timing systems. The spectrum of activities at JPL span from research and development in the areas of precise frequency sources and distribution systems to testing and Implementation of time and frequency subsystems in NASA's Deep Space Network (DSN). These activities are carried out by two groups, one broadly engaged in R&D, and the other in engineering and implementation of F&T systems. Current activities in the R&D areas include the development of a Trapped Mercury Ion frequency standard, Superconducting Cavity Stabilized Maser, Hydrogen maser, and fiber optic time and frequency distribution networks. The engineering and implementation activities include the installation of the new MARK IV Timing Subsystem in the DSN, the development and installation of techniques and methodology for precise time synchronization for the DSN, and the operation of the Frequency Standards Test Laboratory. In October of 1985 the two groups were located in a new facility which houses all the frequency and timing personnel and laboratories, including a unique test facility for characterization of the performance of all frequency standards, time and frequency equipment and components. In this paper details of the activities in frequency and timing at JPL will be presented.
