Sections 1 has updates.

SECTION 1: POLAR APT/LRPT REPORT 19th August 2019.
  ================================================
CHANGES SINCE LAST REPORT.
Meteor M N2-2 has had too many changes to list.

THIS WEEK'S POSSIBLE EVENTS.
Meteor M N2-2 is expected to change on 19th August to 80k and channels
1,2 and 3. Please note that during commissioning parameters are changing
sometimes on a daily basis. Please check groups.

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                No LRPT service
Meteor M N2    137.100 (LRPT)      on
                QPSK, 72k
Meteor M N2-2  137.100 (LRPT)      on    good (commissioning)
                OQPSK,  72k

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.
None expected.


SECTION 2: POLAR HRPT/AHRPT REPORT 19th August 2019.
  ==================================================

None.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

Satellite    Frequency  Antenna    Mode     Image Quality
              (MHz)
NOAA 15       1702.5     Omni      HRPT   Weak(periods of problems)
NOAA 18       1707.0     RHCP      HRPT        Good
NOAA 19       1698.0     RHCP      HRPT        Good

Metop-C       1701.3     RHCP      AHRPT
Meteor M N2   1700.0 see Note 7.
Meteor M N2-2 1700.0 see note 7.(commissioning).

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 and M N2-2 are neither using full HRPT or
   AHRPT and cannot be received using standard receivers. Please see
   other 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.

LAUNCHES.
None expected.
