GOES-J was decomissioned on 14 June 2007. There were two orbit-raising burns spaced 12 hours apart (one to raise apogee, the other to raise perigee), followed by a fuel-depletion burn (to avoid a future debris-causing explosion) and spacecraft shutdown.
GOES-J's momentum wheels became noisy in 1998, and the satellite was shut down and left orbiting in cold storage until 2002. GOES-K was called up in the summer of 1998 to replace GOES-J as the operational GOES-WEST bird at 135W in August 1998. In 2002-2003, GOES-9 was revived by NOAA to provide a temporary on-orbit replacement for Japan's failing GMS-5 satellite. GOES-9 was operated at 155 dgrees east from Fairbanks Alaska until 15 November 2005.

For details regarding broadcast of GOES-9 WEFAX via GMS-5, please see: http://www.jma.go.jp/JMA_HP/jma/jma-eng/contents/info_GMS5.html For the official announcement from JMA, please see: http://www.jma.go.jp/JMA_HP/jma/jma-eng/contents/Start_GOES9.html MTSAT-1R, the successor to GMS-5, is planned for launch in early 2004. For details, see: http://mscweb.kishou.go.jp/general/future_plan/index.htm#1 Below are some of the updated milestones and plans for the operation of GOES-9: **April 26, 2003: GOES-9 on-station normal operation at 155E ** **On May 22, 2003, GMS-5 ceased disseminating high resolution data (with the last GMS image at 00:00Z), and is transmitting GOES-9 WEFAX via the GMS-5 satellite.** - Users who received GMS-5 WEFAX from GMS-5 should not need to make any changes to receive GOES-9 WEFAX via GMS-5 - S-VISSR type data converted from GVAR signals will be distributed via the Internet from the JMA to the National Meteorological Services which made registration to the JMA. This Internet distribution has been already carried out for the S-VISSR data obtained by GMS-5 since 2 December 2002. - GOES-9 data will _not_ be converted to VISSR and relayed through GMS-5 - Imagery is available both via GVAR for direct readout, and from DOMSAT for CONUS users. For users receiving GMS data from Satellite Services Division/SATEPS via McIDAS ADDE, the current GMS data location was replaced by a new GPR server. The IP address will remain the same.

GOES-J has not failed -- it is a on-orbit spare satellite with a remaining lifetime between a day and several years, depending on the vagaries of bearing failure.
GOES-9 was removed from ZAP storage mode (to three-axis control) in November 2001, for a two month monitoring period for orbital maintenance and to evaluate wheel and imaging performance.
GOES-9 was removed from ZAP storage mode (to three-axis control) in December 2001 - January 2002, for a one month monitoring period for orbital maintenance and to evaluate wheel and imaging performance.
Upper/lower IR detector striping was almost unobservable just after launch, but has grown with age.
The scan mirror motor on the Imager has lost its redundant winding due to thermal expansion and contraction of the potting material each day. Therefore, NOAA has decided to turn the Imager away from the sun during the hours before and after midnight for several weeks near the spring and autumn solstices. No GOES-9 images are available during this 6 to 8 hour "mitigation".
During 1997, reception of the GOES-9 downlink at Wallops VA has suffered significant interference for periods of 10 to 60 minutes. Some of this is due to NWS radiosondes launched at 0000 and 1200 UTC, but there are other undiagnosed cases, generally during the local morning hours, 1400 to 1800 UTC. There was generally one unuseable image per day.
In May 2003, while GOES-9 was drifting west of the dateline on its way to Japan, the Attitude and Orbit Control Electronics (AOCE-2) went off-scale, causing large navigation errors in the imagery. NOAA disconnected the AOCE, which normally provides corrections for orbital imperfections. Imaging is still possible.
GOES-9 was removed from ZAP storage mode (to three-axis control) in December 2001 - January 2002, for a one month monitoring period for orbital maintenance and to evaluate wheel andimaging performance. The project scientist analyzed GOES-9 imagery, and wrote a report about the anomalous noise in the detectors:
Coherent noise is analyzed for GOES-9 imagery observed on 8 January 2002. Anomalous semi-harmonic high-frequency noise is apparent in the visible imagery. Of the eight visible detectors, two detectors are found to have 10 counts RMS noise, four detectors have 5 counts RMS, and two detectors have 3 counts RMS (the normal value in GOES-8). The semi-harmonic noise observed in bright sunlit clouds is approximately twice the amplitude observed in dark space. The principal mode found by Fourier power spectra is an irregular "hum" with a 5-to-6 visible sample period, which corresponds to 4100 to 3400 Hz band for a 20380 Hz visible sample clock rate. Many other weak resonances are observed at longer periods, differing from detector-to-detector and modulated during the frame. There are significant correlations in the anomalous noise among the visible detectors, with slow drifts in their mutual coherence over 30 minutes. There is an unresolved question whether the high-frequency noise in the visible detectors (3400 to 4100 Hz) is related to the noise in the low-speed momentum wheels (48 Hz). No high-frequency anomalous noise is observed in the GOES-9 infrared channels, but there is anomalous behavior in the mean dark values near the assumed western space-clamps; west-to-east scans have significant line-to-line variations in channels 2 and 4, with different offsets for each detector.
GOES-9 has rarely been used for special storm scans after becoming operational.
GOES-9 delivers WEFAX routinely to the western hemisphere, particularly useful in South America.
The earth sensors on GOES-9 are less sensitive to sunglint, but there is still some noticeable wobble as the sun passes behind the earth around sub-satellite midnight.
The electro-mechanical failures on GOES-J are in redundant systems:
GOES-9 Momentum Wheel Noise Increase: Starting on March 17, 2004, the wheel current on the GOES-9 momentum wheel 1 showed an increase by about a factor of two, reaching a maximum on March 20, probably due to wheel bearing friction. This increase was associated with a corresponding increase in the noise seen in the visible detector signals. Since then the current has fallen back down, reaching typical pre_event levels on March 29.
On Saturday, February 19, at 15:35Z the GOES-9 fuel line pressure dropped to the bottom end to the telemetry calibration curve. Supporting data (line temperatures, thruster temps, tank pressures, and tank temps) revealed no indication of a physical anomaly. In addition, the attitude data gave no evidence of a torque disturbance. Likely cause of the anomaly is a failure of the pressure transducer for the fuel line. A spacecraft incident report has been written and sent to NASA and SS/L for inquiry. No impact on storage operations is anticipated.
SOCC MORNING REPORT July 28, 1998 Imaging and sounding operations for the GOES-9 spacecraft were terminated at 1600Z on July 27 in preparation for the storage mode operation. The maneuver to begin the spacecraft move to 105 degrees was successfully performed at 0620Z. The satellite was then placed in spin storage mode at 0828Z. The predicted spin axis cone angle was achieved to .25 degrees. Both momentum wheels have been turned off. Post maneuver ranging operations will begin today for a final orbit determination and drift rate calculation. The satellite is predicted to arrive on station on August 17.

Subject: Special GOES-9 Imager Motor Winding Protection Operation Author: firstname.lastname@example.org at EXTERNAL Date: 10/3/97 5:57 PM The next GOES-9 imager motor winding protection operation is scheduled to run from October 13 through October 30, 1997. For this period, the following exclusive schedule will be employed daily to support the special protection operation: From 0423 to 0459 UTC -- no GOES-9 imaging or sounding expected product loss: 0430 UTC McIDAS, GOES-TAP, and AWIPS images From 0500 to 0623 UTC -- routine GOES-9 imaging and sounding operations; exception is a northern hemisphere scan will replace the full disk transmission at 0600 UTC. From 0624 to 1223 UTC -- no GOES-9 imaging or sounding expected product loss: 12 UTC winds; 0630 UTC through 1200 UTC, McIDAS, GOES-TAP, and AWIPS images; 0700 through 1200 UTC, ASOS SCP; 0700 through 1200 UTC, Imager DPI 1224 UTC to 1259 UTC -- GOES-9 routine imaging and routine soundings 1300 UTC to 1329 UTC -- GOES-9 full disk imaging and routine soundings 1330 UTC and on -- routine GOES-9 imaging and routine soundings Expect some imager and sounder navigation irregularities for up to three hours following the daily GOES-9 data outage period. To compensate for some of the lost GOES-9 coverage, exclusive GOES-8 full disk scanning is scheduled daily from 0645 UTC to 1244 UTC, October 13-16, and from 0415 UTC to 1244, October 17-30. To facilitate image navigation and registration recovery following the special motor winding protection period, abbreviated full disk scanning will replace routine scanning operations from 0430 UTC to 1229 UTC on October 31 and November 1.

Subject: GOES-9 Image Sectors From: email@example.com (Jamie Hawkins) Date: Mon, 11 Dec 1995 12:02:53 +0500 GOES-9 continues moving toward 135W at a rate of about 0.93 degrees per day. The spacecraft will arrive on station on January 22. Imager operations during its move will consist of full disks beginning on XX:15 and XX:45 through the 18:45 image on December 18th. Beginning with the 19:30 ingest on that date, a "Routine Mode" scanning schedule will be implemented. The areas scanned were defined for operations at 135W, and therefore may not seem optimum during the move. Here are the specifics of imager scanning in this Routine Mode.
