APT, DIGITAL and GEOSTATIONARY WEEKLY STATUS.
==========================================
Author : Douglas S Deans.
Sections 1, 3 and 4 have updates.
SECTION 1: POLAR APT REPORT -- 2nd January 2006
========================================
Satellite Frequency (MHz) Status Image Quality
NOAA 12 137.500 on good
NOAA 14 137.620 off n/a
NOAA 15 137.500 on good
NOAA 17 137.620 on good
NOAA 18 137.9125 (Note 4) on good
CHANGES SINCE LAST REPORT
None
THIS WEEK'S POSSIBLE EVENTS
Possible change of NOAA 18's APT frequency. See note 4.
NOTES.
1. NOAA 9 was permanently deactivated some years ago and is tumbling
freely. Unfortunately it has a sporadic carrier on 137.500 (varies
quickly according to orientation) and can cause interference to NOAA 12
and NOAA 15.
2. Tiros-N and NOAA 6 are putting a carrier out on 137.500 and will
interfere with NOAA 12 and 15 when their footprints overlap.
3. NOAA 16's APT transmission system failed a few months after launch.
4. NOAA have advised of a possible frequency change for NOAA 18 APT from
137.9125 to 137.100. Likely date is 4th January but timing and
confirmation still awaited from NOAA.
5. Elements are available from :-
http://www.space-track.org and

LAUNCHES.
NOAA N' launch.....2008.

SECTION 2: POLAR DIGITAL REPORT -- 2nd January 2006
===========================================
CHANGES SINCE LAST REPORT.
None.
THIS WEEK'S POSSIBLE EVENTS.
None expected.
Satellite Frequency Antenna Mode Image Quality
(MHz)
NOAA 12 1698.0 RHCP HRPT Good
NOAA 14 1707.0 RHCP HRPT Mixed ( note 1)
NOAA 15 1702.5 Omni HRPT Weak
NOAA 16 1702.5 LHCP HRPT Mixed ( note 3)
NOAA 17 1707.0 RHCP HRPT Poor (note 2)
NOAA 18 1698.0 RHCP HRPT Good
Feng Yun 1C 1700.4 RHCP CHRPT No data (note 4)
Feng Yun 1D 1700.4 RHCP CHRPT Good
NOTES.
1. On 14th April 2004 NOAA 14's AVHRR scan motor stalled. It was assumed
that it would be unlikely to work again.
However on the 16th July 2005 it unexpectedly sprung to life with
nominal currents and more importantly nominal synch delta values. Good
imagery was once again being reported.
UPDATE: Scan motor problems have returned and reports are again mixed.
Some periods of good data, some poor.
2. Problems have developed with STX-3 (1707 MHZ). Power has dropped from
approx. 8W to about 2.4W resulting on a greatly reduced signal strength.
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.
4. Although all channels are being transmitted on Feng Yun 1C, there is no
image data, so the channels are effectively empty.
5. The following HRPT transmitter changes were effective from
30th August 2005. The re-assignments were :-
NOAA 16 changed from STX1 (1698 MHz) to STX2 (1702.5 MHz).
NOAA 18 changed from STX3 (1707 MHz) to STX1 (1698 MHz).

EARS.
Pre-Announcement.
On 31 January 2006, continued access to EARS-ATOVS data via EUMETCast will
be subject to pre-registration and the operation of a EUMETCast reception
station fitted with an EUMETCast Key Unit (EKU).
For more details see:

Access to EARS-ATOVS data via ftp-pull will terminate on 31 January 2006.
The reliability of EUMETCast has proven such that the back-up ftp delivery
is no longer considered necessary for EARS-ATOVS.
My thanks to David Taylor for his help with reports.
