Ground Segment Overview
  Simplified GOES-R System Architecture
image: Simplified System Architecture
Ground support is critical to the GOES-R mission. 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, Maryland, and the Wallops Command Data Acquisition Center (WCDAS) at Wallops, Virginia. A third operations facility in Fairmont, West Virginia, will serve as the Consolidated Backup (CBU) in case of a systems or communications failure at either or both NSOF and WCDAS.

Data Levels
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 generate 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 direct readout users with antenna receives by means of spacecraft relay as GOES Rebroadcast (GRB). Level 1b products and Level 2+ products will be provided to the Product Distribution & Access (PDA) System for users including the Data Archive centers (CLASS).

Prime Contractors

The Harris Corporation, Government Communications Systems Division of Melbourne, Florida is developing the GOES-R GS. The 10-year contract calls for Harris to design, develop, test, and implement the core GS functional elements. Click here for the NOAA press release on the award of the Core Ground System contract.

Harris was also awarded a separate 10-year contract to supply the ground antenna system for GOES-R. The contract includes design, manufacturing, and testing of six new antennas and upgrading four existing antennas at the three ground station facilities. Harris, under the core GS contract, will integrate the antenna system into the core GS. Click here for the NOAA press release on the award of the ground antenna system contract.

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.
