GOES-J STATUS last update: 14 June 2007

There is a scrapbook of GOES-9 Results on-line.

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.

GOES-9 replaces GMS-5

Details:

NOAA's operation of GOES-9 as the operational West Pacific Geostationary satellite at 155 degrees East will terminate on November 15, 2005. The Japanese Meteorological Agency's MTSAT-1R, launched in February 2005 and placed at 140 degrees East, was declared operational by JMA on June 28, 2005.

Agencies and users with operational interests for satellite weather surveillance in the West Pacific, Eastern Asia, or Australia should already be receiving MTSAT-1R HiRID data via direct broadcast, DOMSAT, or from SSD/ESPC (formerly SSD/SATEPS).

Information on the operation, scheduling, imager channels, and other data from MTSAT-1R can be found at the JMA Satellite Activities website at: http://www.jma.go.jp/jma/jma-eng/satellite/index.html

SSD/ESPC users receiving GOES-9 data can access the new MTSAT-1R HiRID datasets via McIDAS from the following server:

DATALOC  ADD  MTS  140.90.195.191

The satellite currently has three sectors that have been put into the following datasets -  the data group for all MTSAT imagery is MTS

Details:

On 0600 UTC May 22, 2003, NOAA's GOES-9, positioned at 155 degrees East,
became the operational meteorological satellite over the West Pacific
and Eastern Asia, replacing the Japan Meteorological Agency's GMS-5
satellite.

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. Current GMS products that
will be converted to GOES-9 is as follows:

Spacecraft

In June and July of 1998, the two main momentum wheels on GOES-J began demanding high power levels to maintain their normally modest rotation rate (2900 rpm), as though the bearings were beginning to fail on both wheels. The buzz from the momentum wheel may be causing the coherent noise in the visible channel. There is one small spare wheel that could be used instead of one failed wheel, but there is no recovery from the failure of both wheels, since two wheels are needed to maintain a stable earth-facing attitude.

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.

Launch

GOES-J was launched successfully at 1:52 am EDT, Tuesday, 23 May 1995. GOES-J's night launch was picturesque and animated. GOES-J was renamed GOES-9 on 31 May 1995, after the main maneuver to get the satellite into a roughly geosynchronous orbit at 90W. Initial engineering tests of the Imager visible scanner were performed on Friday, 9 June 1995, and some nice images were produced. First official GOES-9 full-earth image from 12 June 1995 was quite successful.

Imager

The infrared detectors in the SN04 Imager are the most sensitive ones used in the entire GOES-I/M series.

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.

Sounder

Engineering improvements to the SN04 Sounder will improve its radiometric zero-point stability, a very important feature for measuring small differences between channels in order to estimate atmospheric gradients. The University of Wisconsin has reported some low-frequency noise on-orbit, however.

Post-Launch Plan

GOES-9 conducted science tests for NOAA in the first two weeks of
September 1995 and during all of November 1995. GOES-9 completed checkout at 90W in November 1995, and is now operational as GOES-WEST at 135W longitude, as of 22 January 1996.

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.

Issues

GOES-J was commissioned with 8.5 years of station-keeping fuel remaining on board, and at least 5.5 years of full electrical power.

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:

Updates from NOAA

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:  jpaquett@ssdnotes.wwb.noaa.gov 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.

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.
