Sections 1, 2 and 4 have updates.

SECTION 1: POLAR APT/LRPT REPORT 21st July 2014.
=========================================
Satellite Frequency (MHz) Status Image Quality

NOAA 15 137.620 (APT) on good
NOAA 18 137.9125 (APT) on good
NOAA 19 137.100 (APT) on good but see Note 6
Metop-A 137.100 (LRPT) off see Note 1
Metop-B No LRPT service
Meteor M N1 137.100 (LRPT) sporadic see Note 6
Meteor M N2 commissioning.

CHANGES SINCE LAST REPORT.
Meteor M N2 added.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

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. 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.
During in-fill carrier phase this satellite can cause interference to
NOAA 19 when footprints overlap.

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

LAUNCHES.
None expected.

SECTION 2: POLAR HRPT/AHRPT REPORT 21st July 2014
===========================================
CHANGES SINCE LAST REPORT.
Meteor M N2 added.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

Satellite Frequency Antenna Mode Image Quality
(MHz)
NOAA 15 1702.5 Omni HRPT Weak
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 1701.3 RHCP see note 9.
Metop-A 1701.3 RHCP AHRPT Good (note 5)
Metop-B 1701.3 RHCP AHRPT Good.
Meteor M N1 1700 See note 7.
Meteor M N2 1700 commissioning
NPP 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.
For more information, please see:
http://www.eumetsat.int/Home/Main/Media/Features/710601

6. 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.

7. 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 :-
http://tech.groups.yahoo.com/group/weather-satellite-reports/message/2098.
Continual sporadic problems with transmission.

8. As this weather satellite has no S-band transmitter, it is 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 B. 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.
