Robin Pfister (GOES-R Ground Segment Deputy Project Manager) Geostationary Operational Environmental Satellite R- Series (GOES-R) GOES R Ground Segment Overview Robin Pfister (GOES-R Ground Segment Deputy Project Manager) American Meteorological Society 5th GOES Users’ Conference New Orleans, LA Thursday, January 24, 2008

GOES-R Improvement Summary Improvements over current capabilities Imager (ABI) Better resolution (4X), faster coverage (5X), more bands (3.2X) and more coverage simultaneously Lightning detection (GLM) Continuous coverage of total lightning flash rate over land and water Solar/Space Monitoring (SUVI, EXIS, SEISS) Better Imager (UV over X-Ray) Better Heavy Ion detection, adds low energy electrons and protons Auxiliary Services Higher Data Rates for Environmental Data Relay The large increase in spatial, spectral, and temporal resolution of the ABI of GOES-R increases the data volume and drives a large increase in ground system processing requirements for product generation and for distribution of products to users. Advanced Baseline Imager (ABI) Monitors and tracks severe weather, winds, hurricanes, hazards, etc. Images clouds to support forecasts Volcanic ash tracking, fire and smoke detection, winds and icing detection Geostationary Lightning Mapper (GLM) Detects lightning strikes as an indicator of severe storms Previous capability only existed on polar satellites Solar Imaging Suite (SIS) and Space Environmental In-Situ Suite (SEISS) Images the sun and measures solar output to monitor solar storms (SIS) Measures magnetic fields and charged particles (SEISS) Enables early warnings for satellite and power grid operations, telecom services, astronauts, and airlines Auxiliary Services Environmental Data Relay Search and Rescue

Ground Segment Objectives Support the primary mission operations goals to safely launch and safely operate the GOES-R series spacecraft Design, develop, integrate and test the ground segment in a manner that minimizes the GOES-R ground segment and overall program costs Minimize the impact to existing users during the transition to GOES-R services Provide cost effective ground segment sustainment and maintenance once transitioned to government operations Provide cost effective and timely solutions to meet GOES-R evolving ground segment requirements through the application of open standards, modular, scalable, flexible system design and development and the application of industry standard system and software engineering practices Maintain compatibility with existing and enhanced versions of NOAA institutional systems required to support GOES-R series spacecraft

GOES-R Ground Segment Facilities Notional Functional Overview GOES East GOES West GOES-R Ground Segment Functional Elements GOES-R Re-broadcast Remote Backup (RBU) NOAA Wallops Ground Station (WCDAS) NOAA Satellite Operations Facility (NSOF) GOES-R Ground Segment Facilities Mission Management Product Generation Product Distribution User Community Enterprise Management Archive and Access (CLASS*; ESPC*) *CLASS: Comprehensive Large Array-data Stewardship System ESPC: Environmental Satellite Processing Center Mission Management includes mission (satellite and instruments) operations (telemetry and command), mission scheduling, mission state-of-health trending, and satellite orbital analysis. Product Generation includes algorithm definition, processing raw data, processing to Level 1b (including calibration, & navigation and registration) for rebroadcast, and for creation of higher level data products (Level 2+) including operational formatted products. Product Distribution includes distribution of Level 1b GOES-Rebroadcast data (GRB), eGVAR, and distribution and access to Level 0, 1b, and 2+ data and formatted products to authorized users Enterprise Management Provides situational awareness of all functions of the GOES-R GS by monitoring and reporting the configuration of the security, networks, communications, and operational systems NESDIS operational organizations retain operational roles for the GOES-R Ground System NESDIS Office of Satellite Operations (OSO) will provide mission operations and production of Level 1b data NESDIS Office of Satellite Data Processing and Distribution (OSDPD) will provide product generation and distribution Algorithm development, maintenance and instrument calibration supported by NESDIS Center for Satellite Applications and Research (STAR) The Ground Segment will operate from three sites: The NOAA Satellite Operations Facility (NSOF) in Suitland, MD contains the primary Mission Management (MM), Product Generation (PG), and Product Distribution (PD) functions The Wallops Command and Data Acquisition Station (WCDAS) in Wallops, V A transmits commands, GOES Rebroadcast Data (GRB) and communications services to the satellites, and will ingest telemetry and raw instrument data The Remote Backup facility (RBU) located at a geographically diverse site [TBD] will function as a backup for the MM, and minimal PG and PD functionality for the production and delivery of limited products, and will be concurrently and remotely operated from the NSOF remote site location will have visibility to all operational and on-orbit spare satellites.

Unique Payload Services (UPS) Additional capabilities include improved user services for direct readout users: GOES-R services include: LRIT--Low Rate Information Transmission EMWIN--Emergency Managers Wx Information Network DCS--Data Collection System SARSAT--Search and Rescue GRB – GOES Rebroadcast Follow on of L-Band GVAR EMWIN/LRIT Combination Desired Growth Requirements for GOES-R: EMWIN: 19.2  128 Kbps LRIT: 128  256 Kbps Proposed GOES-R solution: EMWIN and LRIT combined with a data rate of 400 Kbps Higher Data Rates for LRIT, EMWIN, DCS, and GRB Cougar Ace incident off of Alaska (24 rescued) was detected by GOES-11 at 830z (and NOAA-17 at 831z while it was within view of Hawaii).
