Multi-Purpose Time Analyzer and Monitor for Deep Space Network Time Synchronization

Abstract

We report the development of a multi-purpose, automated, and continuously operating Time Analyzer to measure and monitor distributed 1 pps reference signals in the NASA Deep Space Network (DSN). The instrument reports the performance of each 1 pps signal relative to the station master clock and displays time offset and jitter (standard deviation) data for each measurement. The long-term stability of the primary and backup frequency standards are also monitored by measuring time offset data and analyzing over a 24-hour period. The instrument output includes alarms that alert the station operator of anomalies or an out-of-specification condition. All monitor and user displays are developed with Labview and use the LINUX operating system.
