Section 4 has updates.

SECTION 1: POLAR APT/LRPT REPORT 20th October 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) off see Note 6
Meteor M N2 commissioning.

CHANGES SINCE LAST REPORT.
None.

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.
Contact lost with satellite on 23rd September 2014.

7. Elements are available from :-

LAUNCHES.
None expected.

SECTION 2: POLAR HRPT/AHRPT REPORT 20th October 2014
===============================================

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

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.
Contact lost with satellite 23rd September 2014.

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.

THIS WEEK AND FUTURE POSSIBLE EVENTS.
GENERAL NOTE.
14 August- 31 December 2014.
The EUMETCast-Europe DVB-S2 Basic Service is operational. A parallel
operational phase with DVB-S is provided till 31 December 2014, at which
date the DVB-S service will end. Further information is available:
http://www.eumetsat.int/website/home/News/DAT_2305543.html

Meteosat Straylight.
During eclipse seasons, stray light affects the way the spacecraft
instrument is commanded. There are periods where the black body calibration
is performed after the instrument retrace instead of prior to it. This
delays files for the time of the calibration approximately three minutes)
which then affects the data timeliness in the same way. This nominal
calibration activity during eclipse season will therefore cause periods of
noticeable delays to reception of data by Users.
Meteosat Straylight Predictions for Winter/Spring 2014 are available on
EUMETSAT Website:
www.eumetsat.int/Home/Main/ServiceStatus/index.htm?l=en
(See section "Straylight Predictions (XML)")

METEOSAT 10.
20 October 2014 - 24 October 2014.
Planned maintenance on the MSG Ground Segment involving migration to a new
hardware platform.

On 23 October, there will be an associated risk of interruption to the
Meteosat-10 products for up to 2 repeat cycles. Users may also experience
degraded production reporting during this period.
With this new hardware platform, the meteorological product generation will
be modified - it will only start after the reception of the complete
Meteosat image. There will be no changes to the products but this will have
a small impact on the dissemination: products may arrive slightly earlier or
later than presently expected. The difference in dissemination times may, in
some cases, be up to 2 minutes.
A set of meteorological products generated from the new hardware is
available at:
ftp://ftp.eumetsat.int/pub/OPS/out/test-data/Met-Products_MCIC_01-10-14/

METEOSAT 9 (RSS).
