COMMENTS/CHANGES: MISC: N/A NOAA-15: There was relatively little change in the performance of the NOAA-15 bus & payload subsystems during the past week with the exception of the following: The spacecraft is performing nominally in mode with JFILT. Yaw errors are approximately +/- 1 degree (See Figure 1). NOAA-16: There was relatively little change in the performance of the NOAA-16 bus & payload subsystems during the past week with the exception of the following: N/A NOAA-18: There was relatively little change in the performance of the NOAA-18 bus & payload subsystems during the past week with the exception of the following: Nominal performance observed from NOAA-18 MIMU1. MIMU pressure has been dropping at a linear rate for 4 years (See Figures 2 & 3). MIMU1 pressure is now about 6.8PSI. The MIMU1 Z axis LIM reached 0.85 µamp on 24 July 2013 (13/205). Present value is 0.662 µamp. The automatic thruster unloading was deactivated on October 8th, and a switch to RGYRO ESTY (roll) was accomplished on October 9th with MIMU1 in use. The Y axis LIM is down to 62.9% since 20 September 2012 (12/264). NOAA-19: There was relatively little change in the performance of the NOAA-19 bus & payload subsystems during the past week with the exception of the following: NOAA-19 HIRS instrument filter wheel experienced a slight decrease in current 17 Nov 2013 (13/321) 13:00 UTC, which caused all IR radiometrics to decrease and the visible channel to increase slightly (See Figure 4). With this decrease in current, Channel 14 radiometrics are no longer saturated (See Figure 5). Nominal performance observed from NOAA-19’s (See Figure 6). There was relatively little change in the performance of the NOAA Instruments on MetOp-A spacecraft during the past week with the exception of the following: N/A MetOp-B: There was relatively little change in the performance of the NOAA Instruments on MetOp-B spacecraft during the past week with the exception of the following: N/A
