NOAA-15 and 16 Elapsed Time Clock Up

Following is the bulletin issued by SOCC announcing their intentions to
correct the NOAA-15 and 16 elapsed time clocks. The Information
Processing Division will update the level 1B preprocessor replacing our
current adjustments at the same time. The level 1B user should not be
impacted by the update. Direct readout data users should update their
systems accordingly.
Thanks
Emily

"Due to a configuration error in ground equipment, the TIP clock errors
that are being reported for NOAA-15 and NOAA-16 have been determined to
be inaccurate by 900 milliseconds, i.e. actual clock errors are 900
milliseconds greater than the values being reported. The NOAA-15 TIP
clock is now reading 100 milliseconds and the NOAA-16 TIP clock is
reading +100 milliseconds. The actual errors are: NOAA-15 = +800
milliseconds, NOAA-16 = +1000 milliseconds. It is necessary to subtract
1.0 second from both spacecraft clocks to correct this error. These
corrections will take place on August 7th, 2001 via SCT at 23:59:00Z for
the control OBPs. The standby OBPs will be updated via real time
command (in the schedules)."
