SECTION 1: POLAR APT/LRPT REPORT – 13th April 2020.
===============================================
CHANGES SINCE LAST REPORT.
None.
THIS WEEK'S POSSIBLE EVENTS.
None expected.
Satellite Frequency (MHz) Status Image Quality
NOAA 15 137.620 (APT) on periods of synch problems
NOAA 18 137.9125 (APT) on good
NOAA 19 137.100 (APT) on good
Metop-A 137.100 (LRPT) off see Note 1
Metop-B No LRPT service
Metop-C No LRPT service
Meteor M N2 137.100 (LRPT) on
QPSK, 72k
Meteor M N2-2 137.900 (LRPT) off (see Note 7).
OQPSK, 72k
NOTES.
1. 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).
2. NOAA 14 was decommissioned on 23rd May 2007.
3. NOAA 12 was decommissioned on 10th August 2007.
4. NOAA 17 was decommissioned on 10th April 2013.
5. NOAA 16 was decommissioned on 9th June 2014.
6. Elements are available from :-
http://www.space-track.org and
http://celestrak.com/NORAD/elements/
7. Meteor M N2-2 has likely been hit by a micro-meteorite. It has
changed orbit and been de-pressurised. Although under control again
the thermal balance is an issue and main problems are overheating of
the batteries which keep switching to backup. LRPT transmitter cannot
operate under those arrangements and is off permanently.
LAUNCHES.
None expected.
SECTION 2: POLAR HRPT/AHRPT REPORT – 13th April 2020.
=================================================
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(periods of problems)
NOAA 18 1707.0 RHCP HRPT Good
NOAA 19 1698.0 RHCP HRPT Good
Feng Yun 3A 1704.5 RHCP see note 6.
Feng Yun 3B 1704.5 RHCP see note 6.
Feng Yun 3C 1701.4 RHCP see note 9.
Metop-A 1701.3 RHCP AHRPT Good (note 5)
Metop-B 1701.3 RHCP AHRPT Good.
Metop-C 1701.3 RHCP AHRPT
Meteor M N2 1700.0 see Note 7.
Meteor M N2-2 1700.0 see note 7 and 10 on
NPP see Note 8.
NOAA 20 see Note 8.
NOTES.
1. NOAA 14 was decommissioned on 23rd June 2007.
2. NOAA 12 was decommissioned on 10th August 2007.
3. NOAA 17 was decommissioned on 10th April 2013.
4. NOAA 16 was decommissioned on 9th June 2014.
5. 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.
6. 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.
Update: The second in the series, Feng Yun 3B was launched on
4th November 2010. I expect the information above for 3A will
equally apply to 3B.
My thanks to Johnny Lin for drawing this to my attention.
7. It appears that Meteor M N2 and M N2-2 are neither using full HRPT or
AHRPT and cannot be received using standard receivers. Please see
other mails for further explanation :-
http://tech.groups.yahoo.com/group/weather-satellite-report/message/
2098.
8. As those weather satellites have no S-band transmitter, they are
included for information only.
9. I am grateful to David Wright of Dartcom (http://www.dartcom.co.uk)
for providing up to date information for Feng Yun 3C.
Now fully operational but the Chinese have changed the data rate
compared to FY-3A and FY-3C DB downlink data rate is 3.9 Mbps after RS
Encoding.
Frequency is also different - it is on 1701.3 MHz same frequency as
Metop A/B. It still requires a special AHRPT receiver like FY-3A/B.
They have also changed the polarisation of the X-band downlink to
LHCP.
10. Meteor M N2-2 has likely been hit by a micro-meteorite. It has
changed orbit and been de-pressurised. Although under control again
the thermal balance is an issue and main problems are overheating of
the batteries which keep switching to backup. AHRPT is on when
spacecraft (solar panels) are illuminated.
LAUNCHES.
None expected.
