Erroneous Second on Terra Spacecraft FIXED

Post by gumley »

From Bruce Macomber:

Dear Users of Terra Data via Direct Broadcast,
On July 1st (DOY182), the FOT uplinked tables and commands to the Terra S/C to subtract the extra second that was added the previous day. At the day roll-over (183/0000z), a negative second was applied to the S/C, effectively eliminating the erroneous second. The FOT monitored the day roll-over in real time and no issues were observed.

If you experienced any issues during the 182/0000z-183/0000z timeframe, please let me know, so I can capture the impact of this error.

Let me know if you have any questions.

Thank you,
Bruce
