Space Architecture

The GOES-R space architecture will accomplish the following:

• Maintain continuous service from a GOES system that meets the remote sensing requirements as specified by NOAA; that is, to provide for continuous observations of the Earth, its atmosphere, and the solar and space environment, from a

Two operational satellites positioned at 137 degrees West longitude for the Western Operational station, and at 75 degrees West longitude for the Eastern Operational station. During the on-orbit storage period, the satellites will be positioned at 105 degrees West longitude and a Launch/Check-out position is reserved at 90 degrees West longitude.

• Provide for continuous relay of GOES ReBroadcast (GRB) data to direct receive users as a follow on to today’s GVAR data stream. GRB will contain data from all instruments at a higher data rate than current GVAR data.
• Provide for reception and relay of data from ground based Data Collection Platforms (DCP) to the NOAA prime and backup Command and Data Acquisition (CDA) ground stations.
• Provide for continuous relay of Low-Rate Information Transmission (LRIT, formally known as WEFAX) data to small users, independent of all other functions.
• Permit relay of distress signals from aircraft or marine vessels to the Search and Rescue ground stations of the Search and Rescue Satellite Aided Tracking (SARSAT).
• Provide a spacecraft capability for permitting data transmission via the Emergency Manager’s Weather Information Network (EMWIN).
• Provide satellite platforms suitable for supporting the instrument payloads.

The Flight Project will implement the space architecture by issuing separate contracts for the development of the instruments and the spacecraft. The Flight Project will provide launch services and instruments as government furnished equipment (GFE) to the spacecraft contractor. After launch, the spacecraft contractor will support the NOAA Satellite Operations Control Center (SOCC) until the spacecraft checkout is completed and the spacecraft is turned over to NOAA for operations.

The Advanced Baseline Imager (ABI) will provide key performance parameters cloud and moisture imagery for Full Disk, Continental United States (CONUS), and Mesoscale coverage for monitoring, forecasting and severe weather warning. Additional instruments include Space Environment In-Situ Suite (SEISS), Extreme Ultraviolet Sensor/X-Ray Sensor Irradiance Sensors (EXIS), Solar Ultraviolet Imager (SUVI), Geostationary Lightning Mapper (GLM), and Magnetometer (MAG). The instruments will be provided to the Space Segment A&O contractor as Government Furnished Equipment (GFE) for integration into the spacecraft.
