9. POES On-Orbit Status NOAA-17 Launched June 2002 Most Instruments are operating nominally Technical status: -STX-3 on 28April03 step decrease in power output from a nominal of 8watts to 2.48watts. Some degradation to users with dishes less than 1M. Evaluating need to reconfigure transmitters. -STX-4 decrease in power output from a nominal of 7.5watts to 6.4watts during a 10-15mins activation. Further tests show that the transmitter is slow to reach nominal power. Currently used for Svalbard tracking tests. -Digital Tape Recorder #5 anomaly on Feb 15, 2003. Removed from service on Feb16. Investigation underway -AMSU-A1 intermittent radiometric count changes in PLLO channels 9-14. Similar problem on NOAA-16. -AMSU-A1 periodic bias shift in channel 3 observed in internal warm and space view data.

10. POES On-Orbit Status NOAA-16 Launched September 2000 Most instruments are operating nominally Technical status: –Tape Recorder 4B anomaly 01/03. Test show can be used to record TIP data only. Investigation continuing. 4A is nominal. Tape recorders 5A, 5B, remain non-operational. –Channel 3B is selected for AVHRR (01May03). No switching to 3A at terminator. –SARR 121.5 placed in fixed gain mode for testing Dec 1-9, 2002 –AMSU-A1 intermittent radiometric count changes and noise in PLLO channels 9-14. Similar to NOAA-17.

14. POES On-Orbit Status NOAA-15 (continued) Technical status continued: –HIRS filter wheel chronic “minor” current surged week of April 16; Heater turned on to correct –Reduced Gyro test conducted April 19 – 22 successful

15. Other Spacecraft Highlights N-14 On 30 Mar, AVHRR scan motor improved to the point where imagery was bar code free for the first time since May 2003. Shortly thereafter, trend reversed and imagery again degraded. Spacecraft became a “permanent eclipse” vehicle starting on 30 March. Performance being closely monitored but no reconfigurations are currently planned. Bus voltage and shunt load were nominal throughout this reporting period. On 14 April, AVHRR scan motor toggled off then on for testing purposes associated with N16 AVHRR problem. Problems where encountered. No improvement in quality of data.

The project has issued a Special Change to LM to analyze the S/C to the new levels. ECD June 30 th. GSFC/Swales to analyze GFE to the new levels. ECD May 30 th.

36. NOAA-N’ Currently being evaluated by NOAA and DoC Senior Management Lockheed Martin assessment on functionality of: –Both CPUs will have been completely re-certified by end May. –3 of 4 RWAs have been assessed as reusable. –1of 2 MIMUs have been assessed as reusable. Unit with physical damage is functional, but spare is available. –New TCEs are being considered as qualification of the 3 TCEs damaged in the incident is not possible. The POES project at NASA has generated guidelines for the re-certifying the foreign supplied instruments. –DND awaiting the N prime re-build decision before applying funding to the recertification testing of the SARR. –CNES has completed initial assessment of the ADCS and SARP instruments. Awaiting re-build decision to determine qualification test schedule. –MHS Initial optical alignment test performed –No changes noted on limited items tested. –Quasi-optics alignment not tested. Electrical isolation checks performed with nominal results. Proceeding slowly to a power up test. Continuing investigation at a low level. NASA HQ has formed a team to evaluate the progress of Lockheed in rectifying issues identified by the Mishap Investigation Board as possible contributions to the N prime incident. NOAA OSD will have a representative (Fitzmaurice) on the team.
