FTS Report on DOY 160 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. SPC10 SPC40 SPC60 SPC40 SPC60 MINUS MINUS MINUS MINUS MINUS MJD DOY USNO USNO USNO SPC10 SPC10 57903 150 -1.966# 0.532 -0.930 2.498# 1.038# 57904 151 -1.954 0.514 -0.941$ 2.469 1.016$ 57905 152 -1.929 0.499 -0.917 2.428 1.015 57906 153 -1.903 0.483 -0.891 2.386 1.015 57907 154 -1.877 0.466 -0.864 2.342 1.015 57908 155 -1.852 0.451 -0.839 2.302 1.015 57909 156 -1.828 0.433 -0.814 2.261 1.017 57910 157 -1.804 0.418 -0.788 2.221 1.019 57911 158 -1.779 0.400 -0.764 2.179 1.018 57912 159 -1.756 0.385 -0.737 2.140 1.021 57911 158 -1.729* 0.369* -0.711* 2.097* 1.021* 57912 159 -1.705* 0.352* -0.686* 2.056* 1.021* II.

Comments: Values derived from linear least squares extrapolation or interpolation are indicated by (*) next to the time offset. # On DOY 150 (MJD 57903) SPC 10 online frequency was adjusted by 6*E-13. SPC 10 related frequency offsets were calculated from DOY 151. $ On DOY 151 (MJD 57904) SPC 60 online frequency was ajusted by 5.3*E-13. SPC 60 related frequency offsets were calculated from DOY 152. 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.
