The Core Ground Segment is composed of four primary functional partitions:
The Mission Management (MM) function encompasses all operational functions of the spacecraft and instruments. This includes space/ground communications (both uplink and downlink), GOES Rebroadcast (GRB) relay, and raw data processing. MM also monitors the spacecraft health and safety and commands the spacecraft and instruments. It determines the mission scheduling and planning as well as satellite orbit maintenance and control. MM will be in charge of instrument calibration and performance measurements. MM will be able to support up to four GOES-R series satellites.
The Product Generation (PG) function generates all of the Level 0 and higher products from GOES-R raw data. In addition to generating all of the different level products, the PG will also assemble data sets for GRB. PG will run continuously, generating GOES-R products using GOES-R data and ancillary data to meet product spatial and latency requirements.
The Product Distribution (PD) function distributes the GOES-R products created by the PG function. PD sends data to the National Weather Service (NWS) Advanced Weather Interactive Processing System (AWIPS) for immediate use by the NWS forecast offices, GAS for distribution to and search and retrieval by users, and CLASS for long-term storage and management by the NOAA data centers.
The Enterprise Management/Infrastructure (EM/IS) function supports all of the above by monitoring, assessing, and controlling the configuration of the operational systems, networks, and communications for the GOES-R GS. EM serves as the “glue” that links the MM, PG, and PD functions and provides for a degree of automated control for routine system operations and failure recovery.
