Constellation Overview
The National Oceanic and Atmospheric Administration (NOAA) manages a constellation of four geostationary and eleven polar orbiting meteorological spacecraft. The spacecraft supported range in age from 1 to 17 years.
These satellites are distributed among three operational programs: the Geostationary Operational environmental Satellite Program (GOES), Polar Operational Environmental Satellite Program (POES)and the Defense Meteorological Satellite Program (DMSP). DMSP satellites have been operated by NOAA in support of the U.S. AirForce since 1997.

Managing the Nation’s Operational Environmental Satellite Systems
• Provides a continuous flow of global environmental information in support of national operational environmental requirements
• Requires two satellites on-orbit (one in an afternoon orbit and one in a morning orbit) to ensure continuous coverage.

POES Program Overview
POES Satellites provide continuous global environmental observations in support of operation requirements for:
– Weather Forecasting and Space Environment
– Detection of significant environmental events (e.g., fires, oil spills, volcanic eruptions)
– Measurement of climate variables (e.g., atmospheric ozone)
– Ocean observations (e.g., sea surface temperature)
– Collection of data from surface platforms (e.g., buoys)
– Search and rescue

• GOES satisfies national operational environmental requirements for 24-hour observation of weather and Earth’s environment to support storm-scale weather forecasting by forecasters and numerical models
• To meet requirements, GOES continuously maintains operational satellites at two locations (75 degrees West and 135 degrees West), with an on-orbit spare ready in case of failure

GOES Program Overview
• Warnings to U.S. Public -- Detect, track and characterize– Hurricanes– Severe or possibly tornadic storms– Flash flood producing weather systems
• Imagery for weather forecasting
• Sea Surface Temperature monitoring
• Winds for aviation and NWS numerical models
• Environmental data collection – platforms including buoys, rain gauges…
• Search and Rescue

GOES-N Features Summary
• Imaging/Sounding Through Eclipse – Larger Batteries
• Star Trackers as Primary Attitude Reference– Improved Navigation Performance– 2 km Pointing Accuracy vs. 4/6 km Current Performance– Faster Recovery Following Maneuvers
• Elimination of Solar Sail Yields Colder IR Detectors– Lower Noise Performance for IR Channels
GOES-N Operations Differences
• Improved Solar Baffles on Imager/Sounder Telescopes– Can image closer to Sun – No keepout zone for Imager
• Time-Tagged Onboard Commands – Fewer Lost Images
• Yaw Flip Twice per year, near equinoxes
