ABSTRACT
The National Oceanic and Atmospheric Administration (NOAA) has conducted a study, the NOAA Satellite Observing System Architecture (NSOSA) study, to plan for the next generation of weather satellites. This study has been an opportunity to design a modern architecture with no pre-conceived notions regarding instruments, platforms, orbits, etc., but driven by user needs. The NSOSA study team developed and evaluated approximately 100 architecture alternatives, to include partner and commercial contributions that are likely to become available. The study team also collaborated with the NESDIS’ Office of Satellite Ground Services (OSGS) to ensure that the future ground system would support the future satellite architecture.
OSGS’ mission is to sustain legacy ground systems, enable the next generation of satellite ground segments, and create & deploy a common Ground Enterprise Architecture for the future. OSGS has developed the Enterprise Architecture (EA) for Ground Enterprise Architecture Services (GEARS) using EA best practices. GEARS utilizes the Open Group Architecture Framework (TOGAF) Architecture Development Method (ADM), Department of Defense Architecture Framework (DoDAF) Views, and select Federal Enterprise Architecture Framework (FEAF) reference models for governance and development support. The GEARS EA is being operationalized to support a transition from the current state of the NESDIS Ground Enterprise (NGE) to a future enterprise that maximizes use of promoted and/or developed Common Services, with a primary goal of achieving NGE cost efficiencies while continuing to effectively meet the evolving needs of NOAA NESDIS operational users. This presentation will describe the near-term and long-term strategy for implementing and maintaining the GEARS architecture; and lessons learned from what has already been implemented.
