Sections 3 and 4 have updates.
SECTION 1: POLAR APT/LRPT REPORT -- 4th August 2008
===========================================
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.
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 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.
25/02/08 - There is some recent evidence that NOAA 9 is once again
transmitting a spurious carrier from time to time. (I am grateful to
Mike Piper from Oregon 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

SECTION 2: POLAR HRPT/AHRPT REPORT -- 4th August 2008
=============================================
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
Feng Yun 1D 1700.4 RHCP CHRPT Good
Metop-A 1701.3 RHCP AHRPT off (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. Due to a transmitter failure the AHRPT direct readout service is
off until further notice ( this also includes ATOVS etc.).
LAUNCHES.

NOTES.
1. Meteosat 7 stopped its 0° service at 09.00 UTC on 14th June 2006.
2. Meteosat-6 arrived on station at 67.5 degrees East, on the 27 April
2007.
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:-

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. NESDIS Office of Satellite Operations (OSO)/Satellite Operations
control Center (SOCC) will be taking GOES-13 out of storage for a
series of tests beginning August 1, 2008. There will be a North/South
maneuver performed on the spacecraft on August 5, then an East/West
maneuver on August 7. Due to issues with the GOES-11 batteries,
GOES-13 will continue operations through the Fall 2008 eclipse season.
Following the INR startup to begin July 31, GOES-13 will operate the
imager and sounder from its position at 105 degrees West (navigation
summaries can be found at: http://noaasis.noaa.gov/cemscs/navsum.txt
