FTS Report on DOY 282 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 272 (MJD 57294) SPC 10 online maser frequency was adjusted by 4.5*E-13. SPC 10 related frequency was calculated from MJD 57294. 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.
