APT, DIGITAL and GEOSTATIONARY WEEKLY STATUS.
==========================================
Author : Douglas S Deans. dsdeans@tiscali.co.uk
Sections 1, 2 and 4 have updates.
SECTION 1: POLAR APT/LRPT REPORT -- 26th January 2009
=============================================
Satellite Frequency (MHz) Status Image Quality
NOAA 15 137.500 (APT) on good
NOAA 17 137.620 (APT) on good
NOAA 18 137.100 (APT) on good
Metop-A 137.100 (LRPT) off see Note 3
CHANGES SINCE LAST REPORT.
Pre launch report for NOAA N' updated.
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 know 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.
22/07/08 - There is some recent evidence that NOAA 9 is once again
transmitting a spurious carrier from time to time. (I am grateful to
John Cooper from Oxford 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. Elements are available from :-
http://www.space-track.org and
http://celestrak.com/NORAD/elements/
LAUNCHES.
NOAA N' launch..... 4th February 2009.
(Note as of 22nd January the satellite is on the launch pad mated to the
Delta II rocket with final preparations going to plan).

SECTION 2: POLAR HRPT/AHRPT REPORT -- 26th January 2009
==============================================
CHANGES SINCE LAST REPORT.
Pre launch report for NOAA N' updated.
Feng Yun 3A now operational and added to list.
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
Feng Yun 1D 1700.4 RHCP CHRPT Good
Feng Yun 3A see note 5
Metop-A 1701.3 RHCP AHRPT Good (note 4)
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 29 September 2008, EUMETSAT commenced a partial Metop-A AHRPT
Direct Readout service. Due to the operational constraints, the
activation of AHRPT is for a limited geographical region covering
the North Atlantic and European area (southbound passes only). This
service is being introduced for a trial period of up to 2 months,
following which the activation scenario will become operational. For
further details on this service see:
http://www.eumetsat.int/Home/Main/Access_to_Data/Metop__amp__NOAA_Servic
es/SP_1117714487826?l=en
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.

During this period orders will not be processed and catalogue updates are
suspended.
Eumetsat apologise for the inconvenience and thank their users for their
understanding.
