POES Operational Status

Welcome to the Polar Operational Environmental Satellites (POES) spacecraft status page. This site provides up to date status information on each spacecraft and its various subsystems.

Below are the color designations for each satellite status:

Status Color Green Yellow Orange Red Blue Blank
Meaning Operational (or capable of) Operational with limitations
(or Standby)
Operational with Degraded Performance Not Operational Functional,
Turned Off
No Status Reported
Spacecraft Operational Status Status
NOAA-11, -12, -14, -16, -17 Decommissioned RED
NOAA-15 AM Secondary GREEN
NOAA-18 PM Secondary GREEN
NOAA-19 PM Prime Services Mission GREEN

NOTE:  All LTAN values are valid as of September 20, 2023.
