POLAR APT, DIGITAL and GEOSTATIONARY WEEKLY STATUS.
===============================================
Author : Douglas S Deans. dsdeans@tiscali.co.uk
Sections 3 and 4 have updates.
SECTION 1: POLAR APT/LRPT REPORT -- 30th November 2009
===============================================
Satellite Frequency (MHz) Status Image Quality
NOAA 15 137.500 (APT) on good
NOAA 17 137.620 (APT) on good
NOAA 18 137.9125 (APT) on good
NOAA 19 137.100 (APT) on good
Metop-A 137.100 (LRPT) off see Note 3
Meteor M N1 137.100 (LRPT) sporadic see Note 6
CHANGES SINCE LAST REPORT.
None.
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 15 when active on this frequency.
Latest report below.
01/05/09 - Report of consistent interference on NOAA 15 signal when
NOAA 9 footprint overlaps. My thanks to Steven Ross for this report.
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.
7. Elements are available from :-
http://www.space-track.org and
http://celestrak.com/NORAD/elements/
LAUNCHES.
None due.
Possibility of Okean 5 launch 2009/2010
SECTION 2: POLAR HRPT/AHRPT REPORT -- 30th November 2009
================================================
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
NOAA 16 1702.5 LHCP HRPT Mixed ( note 3)
NOAA 17 1698.0 RHCP HRPT Good
NOAA 18 1707.0 RHCP HRPT Good
NOAA 19 1698.0 RHCP HRPT Good
Feng Yun 1D 1700.4 RHCP CHRPT Good
Feng Yun 3A see note 5
Metop-A 1701.3 RHCP AHRPT Good (note 4)
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.
UPDATE: Scan motor performance has recently improved.
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. My thanks
to
Johnny Lin for drawing this to my attention.
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.
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 :-

LAUNCHES.
None due in the near future.

After a short testing campaign, Meteosat-6 is now supporting the DCP
mission over the Indian Ocean during eclipse periods.
3. Insat 3A is a combined data and meteorological satellite.
4. For those interested in EMWIN data, the following sats/frequencies
apply.
GOES 7 (175 W) 1690.725 MHz.
GOES 11 (135 W) 1690.725 MHz
GOES 12 (74.5 W) 1690.725 MHz
For further info. there are many sources but the following is
particularly informative:-
http://iwin.nws.noaa.gov/emwin/user-intro.htm
5. This satellite is also known as HIMAWARI 6.
6. HiRID and WEFAX was discontinued on 12th March 2008. It was replaced
with HRIT/LRIT (after many months of dual dissemination).
7. Only LRIT (1691.0 MHz) is provided in direct readout.
Full HRIT and LRIT service from Eumetcast.
8. Feng Yun 2E has now arrived at its 105° location. Eumetcast data from
FY-2C has now stopped. Data from FY-2E will commence later when
quality is ascertained. FY-2C has now dropped in altitude to begin
its
eastward move away from the operational satellite position.
9. GOES-10, located at 60W longitude, currently provides meteorological
imagery for South America users. GOES-10 has reached its end-of-fuel
life and requires decommissioning. NOAA plans to decommission GOES-10
on December 1, 2009. GOES-10 will be boosted to a disposal orbit
and all GOES-10 user services will end on December 1, 2009, at
1230 UTC.
Dedicated South America imaging will be interrupted at this time.
NOAA
has considered GOES-10 replacement options and has developed plans for
resuming dedicated South America coverage prior to June 2010. During
the interruption period, GOES-12/EAST will continue to provide South
America coverage every half hour during routine scan operations.
