FTS Report on DOY 167 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: $ Starting DOY 162 (MJD 57915) USNO multi-channel receiver has been displaying bad data, which could be due to the Klobuchar calculation. A lot of bad data are being removed by hand. 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.
