FTS Report on DOY 004 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 10 frequency was adjusted by 6*E-13 seconds on DOY 363 (MJD 55194) NOTES:All DSN data are from the new multichannel receivers. SPC 10 and SPC 60 offsets are commonviewed with NIST and with each other. SPC 40 offsets are all-in-viewed with NIST and with SPC 10.
