  1. Agenda Item: 1.b.iNOAA-19, NOAA-18 (IJPS) StatusDec – April 2013 (nb-NOAA-18 data is no longer provided to EUM from NOAA) by: NOAA/Renee SmithDearring POES Engineering Team Lead Tel.: +1-301-817-4117 Mail: renee.smith@noaa.gov

  2. Agenda • Describe Significant events, change of status of NOAA-19 and -18 since last face-to-face meeting (held 12/2012) and any significant anomalies we are operating with: • Items in bold reflect an anomaly we are operating with. • Date format attached to each event: ddMMMyyyy (yy/Jday) • Describe major milestones for POES Operations

  3. Performance Status June 4, 2013

  4. NOAA-19 (1 of 1) • ADACS/FSW • 12 Dec 2012 (12/347) uploaded these two FSW patches: • RGMOON, removes the moon-contaminated quadrant from sun-moon warning occurs in two opposite quadrants when Reduced Gyro (RGYRO) is in control of ADACS. • DRIBBLE, adds a bias to the ADS computation of roll and pitch error angles when entering/exiting a sun-moon warning period. When not in sun-moon warming the bias is gradually dribble away to zero. • 1 May 2013 (13/122) uploaded the Enhanced RGYRO: • Enhancements to the Gyroless (GYE) code • JFILT filters the estimated yaw output from ESTX RGYRO control to smooth out excessive amount/magnitude of torque commands applied to the yaw reaction wheel due to excitation of Solar Array structural frequencies.

  5. NOAA-18 (1 of 2) • EPS/THM • 21 Jan 2013 (13/021) – PSE Phase Controller Switched to Backup • Similar to the 08 Mar 2011 (11/067) incident • Commanded PSE Phase Controller back to primary on 22 Jan 2013 (13/022) • MHS • Channel 5 • 29 NOV 12 (12/334): LO swap A to B, Gain reset to 0dB

  6. NOAA-18 (2 of 2) • SBUV • Chopper Motor Stall 12 Dec 12 (12/347) • Automated macro power toggling began once chopper motor temperature reached 40C. Power toggled when low temperature set-point of 28C reached • 20 Dec 12 (12/355): Removed routine commanding from Schedule • 21 Dec 12 (12/356): Configuration clean-up • 03 Jan 13 (13/003): Modified low temperature set-point for macro power toggling from 28C to 35C • 16 Jan 13 (13/016): Removed low temperature set-point and allowed 200 minute cool-off prior to power toggle • 24 Jan 13 (13/024): Turned off the Calibration Lamp Heater • 21 Mar 13 (13/080): 200 seconds continuous power toggling

  7. Upcoming Spacecraft Events • Upcoming NOAA-18 FSW patches load • MIMU Patches (May 21-23): • Allow continued operation of MIMU with 0.67 PSI while requiring 3.1 PSI for turn-on. • Remove bug preventing power cycling of a MIMU if the other MIMU had a pressure failure. • Substituting a MIMU switch instead of a MIMU power cycle if the MIMU data rate changes to high. • MIMU1OPS Patch: • When either MIMU1 roll or pitch axis Laser Intensity Monitoring (LIM) data reaches 0.85μA, a s/w patch will be uploaded and the alignment matrix for the failed gyro. • Note that MIMU roll gyro supplies Spacecraft pitch data and MIMU pitch gyro supplies Spacecraft roll data. 7

  8. Upcoming Spacecraft Events • Upcoming ADACS Configuration Changes: • NOAA-18 will be put into Gyroless (GYE) while uploading MIMU1OPS patch. • NOAA-18 will be put into Estimated Pitch (ESTZ) if MIMU1 roll gyro fails or Estimated Roll (ESTY) if MIMU1 pitch gyro fails. • NOAA-18 will be put into GYE once both MIMU1 roll and pitch axes LIM data have reached 0.85μA until: • Both gyros have a hard failure (LIM data gets below 0.73μA) • Failed gyros data is collected for one orbit and provided to Lockheed Martin (LM) • LM reviews the collected MIMU raw data and decides if the noise from the failed gyros when projected on the working gyro is: • Not overwhelming the signal from the MIMU 1 X gyro axis: • Upload the alignment coefficients for MIMU 1 Y and Z RLG failure and place NOAA-18 in Estimated Roll Pitch (ESTYZ). • Overwhelming the signal from the MIMU 1 X gyro axis: • Stay in GYE instead of going to MIMU 2 Estimated Yaw (ESTX) ADACS mode which has demonstrated larger attitude pointing errors than GYE. 8
