The key functions of the Ground Segment are as follows:
The Mission Management (MM) encompasses all functions of the spacecraft and instruments operations and health and safety. This includes space/ground communications (both uplink and downlink), GOES-R 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) 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) distributes the GOES-R level 0, level 1, and level 2+ products created by the PG function through a variety of means. Users of GOES-R data, including NOAA weather forecasters, research scientists, and the general public will have different means of accessing GOES-R data. PD sends data to the National Weather Service (NWS) Advanced Weather Interactive Processing System (AWIPS) for immediate use by the NWS forecast offices, PDA for distribution to and search and retrieval by users, and CLASS for long-term storage and management by the NOAA data centers. Additional information regarding GOES-R data access can be found in the User Readiness section of this site.
The Enterprise Management/Infrastructure (EM/IS) supports all of the above by monitoring, assessing, and controlling the configuration of the operational systems, networks, and communications for the GOES-R ground system, as well as providing common insfrastructure and services. 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.
