Section 3 has updates.

SECTION 1: POLAR APT/LRPT REPORT 10th December 2018.
  ==================================================
CHANGES SINCE LAST REPORT.
None.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

Satellite   Frequency (MHz)     Status   Image Quality

NOAA 15      137.620  (APT)      on   periods of synch problems
NOAA 18      137.9125 (APT)      on         good
NOAA 19      137.100  (APT)      on         good
Metop-A      137.100  (LRPT)     off      see Note 1
Metop-B                No LRPT service
Metop-C           commissioning
Meteor M N2  137.900 (LRPT)      on


NOTES.
1. 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).

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

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

4. NOAA 17 was decommissioned on 10th April 2013.

5. NOAA 16 was decommissioned on 9th June 2014.

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

LAUNCHES.
Meteor M N2-2 launch delayed to NET March 2019.


SECTION 2: POLAR HRPT/AHRPT REPORT 10th December 2018.
  ====================================================
CHANGES SINCE LAST REPORT.
None.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

Satellite  Frequency  Antenna    Mode     Image Quality
              (MHz)
NOAA 15     1702.5     Omni      HRPT    Weak (plus periods of problems)
NOAA 18     1707.0     RHCP      HRPT        Good
NOAA 19     1698.0     RHCP      HRPT        Good
Feng Yun 3A 1704.5     RHCP              see note 6.
Feng Yun 3B 1704.5     RHCP              see note 6.
Feng Yun 3C 1701.4     RHCP              see note 9.
Metop-A     1701.3     RHCP      AHRPT  Good (note 5)
Metop-B     1701.3     RHCP      AHRPT      Good.
Metop-C          Commissioning.
Meteor M N2 1700.0 see Note 7.
NPP       see Note 8.
NOAA 20   see Note 8.

NOTES.

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

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

3. NOAA 17 was decommissioned on 10th April 2013.

4. NOAA 16 was decommissioned on 9th June 2014.

5. 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.

6. 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.

7. It appears that Meteor M N2 is neither using full HRPT or AHRPT and
   cannot be received using current receivers. Please see other WSR mails
   for further explanation :-
   http://tech.groups.yahoo.com/group/weather-satellite-report/message/
   2098.

8. As those weather satellites have no S-band transmitter, they are
    included for information only.

9. I am grateful to David Wright of Dartcom (http://www.dartcom.co.uk)
   for providing up to date information for Feng Yun 3C.
   Now fully operational but the Chinese have changed the data rate
   compared to FY-3A and FY-3C DB downlink data rate is 3.9 Mbps after RS
   Encoding.
  Frequency is also different - it is on 1701.3 MHz same frequency as
  Metop A/B. It still requires a special AHRPT receiver like FY-3A/B.
  They have also changed the polarisation of the X-band downlink to LHCP.
  11th July 2015.

LAUNCHES.
Meteor M N2-2 launch delayed to NET March 2019.
