Length of Outage: Approximately 1 hour - 1.5 hours per transition opportunity.

Details/Specifics of Change: The purpose of this notice is to inform multi-mission segments of the plan to move the JPSS Common Ground System, Command, Control, and Communications operations for the JPSS constellation from the A-string to the CBU-string on March 17th, 2022. A backup date for this activity has been scheduled for March 18th, 2022 in the event the first attempt needs to be waived. NPP, N20, DMSP and GCOM-W1 missions may experience data latency during this transition.
