FTS Report on DOY 187 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. NOTES: As of DOY 135 (MJD 54966) SPC 10 data are from the newly installed multichannel receiver commonview with NIST. As of DOY 68 (MJD 54899) data from (SPC40-SPC10) and (SPC60-SPC10) are derived from direct subtraction. As of DOY 158 (MJD 54989) SPC 40 TTR5 single-channel receiver failed. It came back shortly after station personnel power cycled it but failed again soon after, and has been dead since.
