CHANGES SINCE LAST REPORT.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

NOTES.

1. Three of the older NOAA weather satellites which have been
    decommissioned and are tumbling freely are known to sporadically put
out
    a carrier on 137.500 MHz.  The satellites are TIROS-N, NOAA 6 and NOAA
9
    When the relevant footprints overlap this will cause interference to
    NOAA 17 when active on this frequency.
              --- 11th March 2011 update for NOAA 9. ---
    Mike Piper from Oregon has provided a further update on NOAA 9.
    In addition to the previous reports there has been no further signals
    found.  As there has been nothing from the satellite since about
October
    2010, I now consider the satellite to be dead. No further reports to
be
    issued unless a satellite signal is detected.
    My thanks to Mike for his report and continued monitoring.

2. NOAA 16's APT transmission system failed a few months after launch.

3. Metop-A's A-side LRPT transmitter has failed.  Currently the redundant
   B-side transmitter is off until further notice (No further service
   expected due to interference with HIRS instrument).

4. NOAA 14 was decommissioned on 23rd May 2007.

5. NOAA 12 was decommissioned on 10th August 2007.

6. Signals have been reported from Meteor M N1 but they are
    sporadic with periods off.  Although classed as LRPT it does not
    conform to the CGMS standard.

7. NOAA 17 has scan motor problems with rising motor currents.
    Constant rephase by the MIRP was causing data dropouts on all the HRPT
    stream and APT and GAC derivatives.
    Auto re-phase has now been disabled and the resulting AVHRR products
are
    almost all unusable.  Daily MIRP rephasing via the Stored Command
Table
    began on 18 May 2010 (10/138) - at the first pass over the South Pole
    each day.
    Update 29/09/10 :-  Further deterioration in scan motor performance
with
    no useable data from the AVHRR instrument. Scan motor has stalled.

8. As of 12th October 2010 at 15.00 UTC the following APT frequencies
    applied :-
    NOAA 17    137.500 MHz.
    NOAA 15    137.620 MHz.

9. Elements are available from :-
    http://www.space-track.org    and
    http://celestrak.com/NORAD/elements/

LAUNCHES.
None due in the near future.

Meteor M N1   1700    See note 6.

NOTES.

1.  NOAA 14 was decommissioned on 23rd June 2007.

2.  NOAA 12 was decommissioned on 10th August 2007.

3. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
    similar  to those on NOAA 14 (and previously NOAA 15).
    Since then reports have been mixed.  Some periods of good data, some
    poor.

4. On 25 May 2009, Eumetsat extended the coverage of the Advanced High
    Resolution Picture Transmission (AHRPT) system on Eumetsat's Metop-A
    polar-orbiting satellite. The improved service provides additional
    coverage over the Gulf of Mexico and Indian Ocean regions.
    For more information, please see:
    http://www.eumetsat.int/Home/Main/Media/Features/710601

5. Feng Yun 3A was declared operational on 12th January 2009.
   I am also grateful to Dave Wright of Dartcom for confirming that
   unfortunately (as usual) the Chinese have not strictly complied with
the
   CGMS AHRPT Global Standard so reception using a standard Metop AHRPT
   receiver is not possible.
   Update:  The second in the series, Feng Yun 3B was launched on
   4th November 2010. I expect the information above for 3A will
   equally apply to 3B.
   My thanks to Johnny Lin for drawing this to my attention.

6. It appears that Meteor M N1 is neither using full HRPT or AHRPT and
    cannot be received using current receivers.  Please see other WSR
mails
    for further explanation :-

    Constant rephase by the MIRP was causing data dropouts on all the HRPT
    stream and APT and GAC derivatives.
    Auto re-phase has now been disabled and the resulting AVHRR products
