The GOES-R Ground System (GS) will produce a much larger set of products with higher data density than previous
GOES systems. This requires considerably greater compute and memory resources to achieve the necessary latency and
availability for these products. Over time, new algorithms could be added and existing ones removed or updated, but the
GOES-R GS cannot go down during this time. To meet these GOES-R GS processing needs, the Harris Corporation will
implement a Product Generation (PG) infrastructure that is scalable, extensible, extendable, modular and reliable. The
primary parts of the PG infrastructure are the Service Based Architecture (SBA) and the Distributed Data Fabric (DDF).
The SBA is the middleware that encapsulates and manages science algorithms that generate products. The SBA is
divided into three parts, the Executive, which manages and configures the algorithm as a service, the Dispatcher, which
provides data to the algorithm, and the Strategy, which determines when the algorithm can execute with the available
data. The SBA is a distributed architecture, with services connected to each other over a compute grid and is highly
scalable. This plug-and-play architecture allows algorithms to be added, removed, or updated without affecting any
other services or software currently running and producing data. Algorithms require product data from other algorithms,
so a scalable and reliable messaging is necessary. The SBA uses the DDF to provide this data communication layer
between algorithms. The DDF provides an abstract interface over a distributed and persistent multi-layered storage
system (memory based caching above disk-based storage) and an event system that allows algorithm services to know
when data is available and to get the data that they need to begin processing when they need it. Together, the SBA and
the DDF provide a flexible, high performance architecture that can meet the needs of product processing now and as
they grow in the future.

The next generation of NOAA's Geostationary Operational Environmental Satellite system, Series R (GOES-R)
provides continuity of the GOES mission and improvement of its remotely-sensed environmental data. The GOES-R
system consists of the Space and Ground Segments. The Space Segment consists of spacecraft bus, its remote-sensing
instruments, and communications payloads; while the Ground Segment consists of all Earth-based functions, provides
satellite operations and instrument product generation and distribution. This paper presents an overview of the GOES-R
Ground Segment (GS) architecture as it continues to evolve consistent with the GOES-R Ground Segment Project (GSP)
approved requirements documents. The GOES-R Ground Segment operates from three sites. The first is the NOAA
Satellite Operations Facility (NSOF) in Suitland, MD which houses the primary Mission Management (MM), and
selected Enterprise Management (EM), Product Generation (PG), and Product Distribution (PD) functions. The Wallops
Command and Data Acquisition Station (WCDAS), located in Wallops, VA, provides the primary space
communications services, EM and MM functions, and selected PG and PD functions. The third site is a geographically
diverse remote backup facility (RBU) located at Fairmont, WV. The architecture has been developed to allow integrated
operation within a geographically distributed framework. Because of the unique configuration of the Mission
Management Element, the Wallops Command and Data Acquisition Site will have the ability to assume control of
satellite operations in the event of an emergency - when authorized by the primary NSOF controllers. This concept
allows the Enterprise Management element to have available a wide range of capabilities governed by operations policy
rather than the need for system upgrades. This concept also provides flexibility for addition and deletion of modules for
major functions. The use of Service Based Architecture concepts within the Product Generation element (PG) provides
service interaction capabilities for product generation with only a fraction of the necessary overhead.
The next-generation Geostationary Operational Environmental Satellites (GOES), designated the GOES-R Series, will
provide continuity and improvement of remotely-sensed environmental data from a geosynchronous orbit in the 2015-
2028 era. The GOES-R Ground Segment (GS) Project will acquire the integrated, distributed GS that will conduct
satellite operations and product generation and distribution. This paper describes improvements in GOES-R sensors and
measurements over previous GOES satellites and facets of the product generation subsystem capabilities. The GS will
be capable of producing several key environmental products at low latency on a continuous basis.
