FTS Report on DOY 319

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.

III.
Comments: SPC 40 GPS receiver A failed on DOY 256 (MJD 56548) /1138 UCT. SPC 40 data between DOY 257 (MJD 56549) and DOY 316 (MJD 56608) come from GPS receiver B.



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.
