Abstract
The NASA-JPL Frequency and Timing System (FTS) of the Deep Space Network (DSN) consists of a collection of three sets of clocks (located in Australia, California, U.S.A., and Spain) driven by independent atomic oscillators. It is the synchronization of the output frequencies (syntonization) of these oscillators (reference frequency standards) that is reported here. Prior to 1980 there was no DSN direct specification of syntonization. However, there was an implied specification of a +5.5 X 1 012 related to the DSN time synchronization specification of a +100 microseconds. Both the syntonization within the three sets and the syntonization of the sets to the international standard [International Atomic Time (TAI, UTC (BIH))] are considered.
