## STATUS OF OPERATIONAL SATELLITES

- 4

**STATUS OF**** OPERATIONAL SATELLITES**

_**NOAA-17/M **_**(Launched June 2002)**
- mid AM Satellite (Primary orbit)
*DCS Fully Operational*
- AMSU A1 failure-power supply
- Technical status:
- STX3 degradation (affects very small dish users of HRPT)
- Currently, SOCC retrieves all DCS data for every 24 hour period through GAC playbacks with primary morning mission priority (10-11 playback passes/day).

## STATUS OF OPERATIONAL SATELLITES

- 5

**STATUS OF**** OPERATIONAL SATELLITES**

_**NOAA-16/L **_**(Launched Sep 2000)**
- PM Satellite (Primary orbit)
*DCS Fully Operational*
- AVHRR and HIRS performance has been erratic and necessitated NOAA N call-up
- Technical status:
- 3 of 10 tape recorders have failed. Another failure could impact mission data availability.
- Transmitter for upper frequency (1707 Mhz) HRPT degraded, HRPT move to lower frequency (1698 Mhz). No visible impact to users.
- Currently, SOCC retrieves all DCS data for every 24 hour period through GAC playbacks with primary PM mission priority (10-11 playback passes/day).

## STATUS OF OPERATIONAL SATELLITES

- 6

**STATUS OF**** OPERATIONAL SATELLITES**

_**NOAA-15/K **_**(Launched May 1998)**
- Primary AM Satellite, due to erratic AVHRR, HIRS, and AMSU on NOAA-16 and NOAA-17
- Most instruments operating nominally
*DCS Fully Operational*
- Technical Status:
- Currently, SOCC retrieves all DCS data for every 24 hour period through GAC playbacks with primary morning mission priority (8 playback passes/day).
- Antenna anomalies allow only omni directional antennas to be used for data retrieval. Affects data reception facilities gain margin, no known impacts to operational system.

## STATUS OF OPERATIONAL SATELLITES

- 7

**STATUS OF**** OPERATIONAL SATELLITES**

_**NOAA-14/J**_** (Launched Dec 1994)**
- Backup PM Satellite;
*DCS Fully Operational*
- Currently, SOCC retrieves all DCS data for every 24 hour period through STIP playbacks with backup morning (drifted into N15 orbit) mission priority (4 playback passes/day).
_**NOAA-12/D**_** (Launched May 1991)**
- Backup AM satellite
*DCS Fully Operational*
- Currently, SOCC retrieves 3 hours (2 orbits) of DCS data for every 24 hour period through a single STIP playback with backup morning mission priority. (1 playback pass/day, not routine coverage).
_**NOAA-11/H**_** (Launched Sept 1988)**
- Deactivated June 16, 2004 with DCS community “blessing”
