FTS Report on DOY 021 I. The following are clock offsets, in microseconds between the clocks at each DSN complex and each complex relative to UTC(NIST). The offset is a mean of readings using several GPS space vehicles in common view.

Comments: * Values derived from linear least squares extrapolation or interpolation # SPC 40 experienced a failed power supply to the CRG on DOY 11/0504 UTC (MJD 54842). # Maintenance personnel replaced the 10 MHz distribution amplifier. # The SPC 40 CRG was fixed on DOY 11/2310 UTC (MJD 54842). The Master clock was re-sync. $ SPC 40 HM1 was swapped back to be prime at about DOY 20/2140 UCT. Frequency was adjusted by 4.3*E-13 seconds. ! SPC 60 offsets that don't coincide with TA GPS true time.
