Topic: S-NPP Table 21 Upload planned for Tuesday December 5, 2017

Date/Time Issued: December 4, 2017 2042Z

Products or Data Impacted: None Expected

Date/Time of Initial Impact:  December 5, 2017 1345Z

Date/Time of Expected End: December 5, 2017 1532Z

Length of Outage: See details below

Details/Specifics of Change:  

On Tuesday December 5, 2017 a Command Block Memory (CBM) Table (Table 21) will be re-loaded to S-NPP which restores the No-Slew On-board Stored Maneuver Sequence (OSMS) capability. The activity will be conducted during the Svalbard ground contact at 13:45Z. The on-board CSM and CBM will be stopped for table load, and will prevent some of ATMS Scan Reversals from running.  Scan Reversals will be managed via ground command and may not coincide with nominal cadence, and some reversals may be missed.

Timeline of activities are as follows:

Tuesday December 5, 2017:
13:48:01Z - 13:59:07Z Quiet commanding period during SVL 31641 for CBM upload. CSM and CBM stopped for approximately 5 minutes during upload.
13:54:13Z: Time when normal ATMS scan reversal would have been commanded from CSM.
13:56Z: Approximate time for manual ATMS scan reversal. Subject to miss reversal during this orbit.
14:44:57Z: Time when nominal ATMS scan reversal would have occurred over the South Pole
14:47Z: Approximate time of ATMS scan reversal over South Pole due to manual commanding above.  Subject to miss reversal during this orbit.
15:32:01Z: Nominal ATMS Cadence resumes when ATMS Scan Reversal CBM called from CSM
