FTS Report on DOY 102 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: @ Following the SPC 10 scheduled power outage on DOY 097 (MJD 56389) the Master Clock was recovered to -0.63 microseconds relative to USNO. % SPC 10 time offset was extrapolated from 56390 to 56393. # SPC 10 frequency offsets are calculated from 56390 to 56393. 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.
