FTS Report on DOY 200 I. The following are clock offsets, in microseconds between the clocks at each DSN complex and each complex relative to UTC(USNO). The offset is a mean of readings using several GPS space vehicles in common view.

Comments: # On DOY 191 (MJD 56117), SPC 10 replaced worn fuses of the 100 MHz Distribution Assembly, and re-synced the time with the GPS. NOTES: All DSN data are from the new multichannel receivers. SPC 10 and SPC 60 offsets are commonviewed with USNO and with each other. SPC 40 offsets are all-in-viewed with USNO and with SPC 10.
