Abstract:

Several activities are currently underway at the Jet Propulsion Laboratory in the frequency and timing systems. The development of the sources of precise frequencies includes work on the hydrogen maser, the trapped mercury ion standard, and cryogenic resonators. Precise frequency and time distribution systems are also under development based on fiber-optic systems. These activities are supported by the development of techniques, equipment, and methodologies that allow characterization of the stability and noise. The implementation of frequency and timing systems is also ongoing with efforts directed towards precise synchronization of stations via the OPS system, computerization of the status monitoring capability, automation of the Allan variance measuring equipment, and the distribution of stable and low phase noise 100 MHz signals to the antenna. The activities of the groups involved with the above is carried out in a new Frequency Standards Laboratory facility which houses offices and labs. This facility also houses the test and characterization laboratory which is equipped with unique instruments and environmental chambers. A comprehensive testing and characterization of the stability of all frequency standards and associated components and equipment is possible with this capability. The present and future efforts at the Jet Propulsion Laboratory will ensure that the frequency and timing requirements of the Deep Space Network continues to support the various missions and science activities.
