What is GOES?

• GOES Geostationary Operational Environmental
  Satellite
• Operated by the NOAA and NASA
• It is used to support weather forecasting, severe
  storm tracking, and meteorological research
• Views continental US, Pacific and Atlantic Ocean,
  central and south America, southern Canada
• Used to get frequent cloud images, monitor
  earths surface temperature and water vapor
  fields, and sound the atmosphere for its vertical
  thermal vapor structures

History of GOES

• The first launch was in 1974 and the satellite
  was called SMS-1
• First GOES satellite was launched October 16th,
  1975
• After reaching orbit, GOES satellites are given
  numbers, so GOES-A becomes GOES-1
• SMS-A through GOES-C
• Essentially the same spacecraft
• GOES-D
• Improved data transmission
• GOES-H
• SARSAT
• GOES-I
• 3 axis stabilized
• Improved weather imaging and atmospheric sounding

History of GOES

• There are currently 4 satellites in operation
• GOES 9
• GOES 10
• GOES 11
• GOES 12
• There are other GOES satellites in orbit, but
  they are either inactive or being used for
  different reasons.

7
Instrumentation on the current GOES

• Imager
• Sounder
• Space Environment Monitor
• Ground Based Data Collector and Relay

8
GOES-R

• The next generation satellite in the GOES series
• Being developed by NOAA in partnership with NASA
• Will incorporate technically advances third
  generation instruments and spacecraft
  enhancements to meet evolving observational
  requirements of forecasting

Instruments on GOES-R

• Environmental Sensing Payloads
• Advanced Baseline Imager (ABI)
• Space Environmental In-Site Suite (SEISS)
• Solar Imaging Suite (SIS)
• Geostationary Lightning Mapper (GLM)
• Hyperspectral Environmental Suite (HES)
• Auxiliary Communication Services
• Data Collection
• Data Broadcast
• GOES Re-Broadcast (GRB)
• Search and Rescue (SAR)
• Emergency Managers Weather Information Network
  (EMWIN)
• Low Rate Information Transmission

10
Advanced Baseline Imager (ABI)

• Features 16 channels
• Two visible and 14 near infrared and infrared
• Spatial resolution
• 0.5 km in the visible band
• 1 km for the near infrared
• 2 km for the infrared
• In contrast the current GOES imager has only 5
  channels with resolutions 2 4 km.

GOES-R increased temporal coverage can be
illustrated by comparing the 5-minute coverage of
current GOES (left) with the 5-minute coverage
from the simulated GOES-R (right). GOES-R can
image the entire hemisphere in one-sixth the time
it takes for the current GOES system.

Space Environmental In-Situ Suite (SEISS)

• It will provide real-time measurements of the
  charged particle environment in geosynchronous
  orbit
• Consists of 3 sensors
• MPS magnetospheric particle sensor
• EHIS energetic heavy ion sensor
• SGPS solar and galactic proton sensor

Measurements GOES-R Current GOES
Electrons 30eV to 4MeV 30eV to 4MeV
Protons 30eV to 500MeV 80KeV to 700MeV
Solar Ion Mass Groups He, C-N-O, Ne-S, and Fe alpha particles only
The GOES-R magnetometer will measure the Earths
geomagnetic field in three-axes, providing
information on geomagnetic activity in space.
17
Solar Imaging Suite (SIS)

• Consists of 3 Sensors
• XRS Solar X-Ray Sensor
• EUVS Extreme UltraViolet Sensor
• SXI Solar X-Ray Imager

EUVS 5 127nm 10 126nm
SXI 0.6 10.0nm 0.6 6.0nm

The Geostationary Lightning Mapper (GLM)

• sensitive enough to detect 7090 percent of all
  lightning strikes
• help predict severe storms by continuously
  tracking the intensity, frequency, and location
  of lightning discharges
• provides rapid information that could be
  correlated with radar returns, cloud images, and
  other meteorological data
• Aerospace will support all these instruments
  through design, trades, satellite integration,
  and operations.

20
Hyperspectral Environmental Suite (HES)

• It will perform three tasks and one goal tasks
• Disk sounding
• Coastal waters imaging
• Severe weather/Mesoscale sounding
• The goal task is Open Ocean Imaging
• There is a huge improvement over the current
  sounder.
• The HES coverage rate will be about 5 times
  faster than the current sounder
• Regular coverage of the sounder can extend over
  an area that is much larger than the CONUS
• The number of spectral channels will also
  increase from 18 IR bands to about 1500 IR bands

21
Communication

• Communication Services
• Data Collection
• Data Broadcast
• GRB GOES-R ReBroadcast
• SAR Search and Rescue
• EMWIN Emergency Managers Weather Information
  Network
• LRIT Low Rate Information Transmission

22
Ground Systems

• Troubleshooting and Challenges
• Ground facilities will need to include a remote
  backup location, so its survival will not be
  threatened by the weather at primary sites.
• GOES-R will maintain a 30-day archive of raw data
  records and a 3-day archive of reconstructed
  unprocessed instrument data at full space-time
  resolution with supplemental information to be
  used in subsequent processing appended (Level 0).
  
• GOES-R will generate nearly 16 terabytes per day
  of meteorological and environmental (Level 2)
  products

23
Conclusion

• The GOES-R system will transition to operations
  around 2014, with the first launch planned for
  late in 2012.
• The GOES-R satellite series will operate for more
  than 16 years, providing regional environmental
  imagery and specialized meteorological, climatic,
  terrestrial, oceanographic, and solar-geophysical
  data.
• GOES-R will support a wide variety of end users
  such as National Weather Service, Federal
  Aviation Administration, Environmental Protection
  Agency, and Department of Homeland Security.
  GOES-R products will be useful to much of
  America's industry, including agribusiness,
  transportation, and construction.
• Aerospace participation in research, source
  selection, and program office activities has been
  instrumental in identifying difficult issues
  facing the GOES-R system.
• Aerospace's continued support in the upcoming
  acquisition phase can help ensure that the final
  architecture will be both feasible and powerful
  enough to meet the diverse user requirements.
• Aerospace expertise and continued involvement
  should enable NOAA to provide an improved
  geostationary weather and environmental sensing
  capability that can serve up to 2030.
