NOAA’s Polar-orbiting Operational Environmental Satellites (POES) Overview
Tom SchottNESDIS/OSD Satellite Product ManagerU.S. Department of Commerce - NOAA
NOAA Satellite ConferenceApril 8-12, 2013
1
Topics• Polar-orbiting Operational Environmental
Satellite (POES)• Initial Joint Polar-orbiting System (IJPS)
2
POES Mission• To provided uninterrupted flow of global environmental
information in support of operational requirements for:– Global Soundings – Global Imagery– Global and Regional Surface & Hydrological Obs– Direct Readout, Data Collection, Search and Rescue– Space Environment and Ozone Observations
• To establish long-term continuous data sets for climate monitoring and change predictions
• Uninterrupted data requires two satellites for continuous coverage placed in orbits selected to optimize support for both weather services and climate requirements.

NOAA-17 Decommissioning• After nearly 11 years of
service NOAA-17 will be decommissioned on April 10, 2013
• Decision based on evaluation of NOAA-17’s health, ability to provide meaningful data to the scientific and weather community, and resource demands in NESDIS/OSPO
• Since launch, the electrical power subsystem has degraded extensively, and AVHRR and AMSU-A1 instruments are no longer functional
• Metop-A and B will replace NOAA-17’s data coverage
10
NOAA-17 (NOAA-M) was launched on June 24, 2002
Initial Joint Polar-orbiting System (IJPS)
• IJPS consists of two independent, but fully coordinated, polar satellite systems to provide for the continuous and timely collection and exchange of environmental data from space.
• Afternoon orbit provided by NOAA – NOAA-18 launched May 2005– NOAA-19 launched Feb 2009
• Mid morning orbit provided by EUMETSAT– MetOp A launched Oct 2006– MetOp B launched Sep 2012– MetOp C planning launch date 2017

Summary• NOAA continues to partner with EUMETSAT in
the mid-morning polar orbit• NOAA-19 is the last of the POES satellites for the
afternoon polar orbit– POES satellites have served the nation since the early
1960s• Joint Polar Satellite System (JPSS) ensures
afternoon polar orbit capabilities continue
