Details/Specifics of Change: The purpose of this notice is to inform multi-mission segments of the plan to move the JPSS-2 (N21) Common Ground System, Command, Control, and Communications operations for the JPSS constellation from the B string to the A string on February 28th, 2023. A backup date for this activity has been scheduled for March 2nd, 2023 in the event the first attempt needs to be waived. NPP, N20, N21, DMSP and GCOM-W1 missions may experience data latency during this transition.
