NOAA is developing a state-of -the-art ground system that will receive data from the GOES-R spacecraft and generate real-time GOES-R data products. This is accomplished via a core set of functional elements (mission management, product generation, product distribution, and enterprise management/infrastructure), an antenna system, and a product access element.

The GS will operate from two primary locations: the National Satellite Operations Facility (NSOF) in Suitland, MD, and the Wallops Command Data Acquisition Center (WCDAS) at Wallops, VA. A third operations facility in Fairmont, WV will serve as the Remote Backup (RBU) in case of a systems or communications failure at either or both the NSOF and WCDAS.
• Level 0:
Unprocessed instrument data at full resolution
• Level 1b:
Level 0 data with radiometric and geometric correction applied to produce parameters in physical units
• Level 2+:
Derived environmental variables with comparable to Level 1 spatial and temporal resolution
Roles and Responsibilities
The GOES-R Ground Segment (GS) will receive the raw data from GOES-R series spacecraft and generating Level 0, Level 1b and Level 2+ products. The GS will also make these products available to users in a timely manner consistent with the GOES-R latency requirements.Level 1b data from each instrument and Level 2 data from the Geostationary Lightning Mapper (GLM) will be distributed to the hemisphere by means of spacecraft relay as GOES-R Rebroadcast (GRB). Level 0 data will be provided to the Comprehensive Large Array-data Stewardship System (CLASS) for archival storage.
Solers, Inc. of Arlington, VA, is developing the Environmental Satellite Processing and Distribution System (ESPDS), which provides the GOES-R Access Subsystem (GAS) functionality required for terrestrial, near-real time distribution of higher-order GOES-R products.
