Declaration of the Operational Status of NOAA-18
*Date/Time(UTC) Message Issued:*
29 August 2005,2030 UTC
*Date/Time(UTC) of Initial Implementation:*
30 August 2005, Time 0000 UTC
*Details/Specifics of Change:*
NOAA has established a NOAA-18 operational implementation date of August30, 2005. NOAA-18 will become the primary afternoon satellite in the POES constellation with priority over NOAA-16 in the event of conflicts. Recognizing that some end users are still transitioning to NOAA-18, we will continue to make all NOAA-16 orbital data available. The attached PDF contains information on the constellation change planned for all POES when NOAA-18 becomes operational. This constellation represents the best mix of operational support without jeopardizing the safety and health of our satellites.

POES Constellation Plan
NOAA-18: Primary Operational PM Satellite
All instruments and services are operational. However, the infrared temperature sensor (HIRSl4)
is experiencing an anomaly where channels 1-4 and 12 are out of specifications. The sensor is
considered operational with limitations and the anomaly is under investigation. Per established
NESDIS procedures, the imager channel 3b will be left on to support the fire detection
community. We will process stored global (GAC) and local area (LAC) data and direct readout
(HRPT) data in near-real time. LAC scheduling will start on August 30, 2005
NOM-17: Primary Operational AM Satellite
The microwave temperature instrument has failed. All other instruments and services are
operational. Per established NESDIS procedures, the imager channel 3a will on during day light
conditions to support the snow hydrology community and 3b will be on during night conditions.
We will process stored global (GAC) and local area (LAC) data and direct readout (HRPT) data
in near-real time.
NOAA-16: Back-up Operational PM Satellite
The imager, infrared sounder and ozone instruments are operational with limitations. All other
instruments are operational. All services are operational except APT which has failed. We will
process stored global GAC data but some passes may be delayed due to resource limitations.
NOAA-15: Back-up Operational AM Satellite
The imager, microwave temperature, infrared sounder instruments are operational with
limitations. All other instruments and all services are operational. Since NOAA-17's
microwave temperature sensor failed, we will process stored global (GAC) data in near-real time
on a "best level of effort basis". NOAA-15 will have priority over NOAA-16 if resource
NOAA-14: Back-up Operational PM Satellite
The imager is operating with limitations. All other instruments are marginal except the
microwave and stratospheric sounder units which are operational. The search and rescue
processor and APT services have failed. All other services are operational. We will process
non-imagery stored global data, but only download the stored data four or less times a day.
There may be some orbital passes lost due to resource limitations.
NOAA-12: Standby Satellite
The imager and space environmental monitor are operational. All other instruments have failed.
Direct readout services (HRPT and APT) will continue. We will only download stored data once
or twice a day to monitor satellite health. (Note: N-12 does not have a search and rescue
