FTS Report on DOY 154 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: 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. FTS Contacts: Connie Dang (626)305-6194 :: Linh La (626)305-6184 Page 1
