POLAR APT, DIGITAL and GEOSTATIONARY WEEKLY STATUS.
===============================================
Author : Douglas S Deans. dsdeans@tiscali.co.uk
Section 4 has updates.
SECTION 1: POLAR APT/LRPT REPORT -- 17th August 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
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.
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 -- 17th August 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)
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.
LAUNCHES.
Meteor M N1 launch tentatively set for 15th September 2009.
