Meteosat-5 IODC errors

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Folks,

I am seeing three lots of errors on Meteosat-5 (Indian Ocean)
segments. These have been reported informally to Eumetsat but are
still outstanding. These problems are:

1 - Prolog sometimes coming after the first data segment. The
prolog carries the thermal calibration information.

2 - Last segment arrives before other segments, causing a temporary
save of an incomplete image.

3 - Visible channel segments 2 or 3 are sometimes missing, for
example from yesterday's report:

Missing segments report, 2003 Dec 13
Cycle: 0300 met5-vis seg 2
Cycle: 1200 met5-vis seg 3
Cycle: 1500 met5-vis seg 2 3

As long as the calibration is stable, (1) is not a problem.
(2) is an incovenience as it can take up to three hours for the MSG
Data Manager to recover from the problem and save the complete image
(when the next scan arrives). (3) is a new problem that I have only
noticed in the last couple of days. I am seeing it on two PCs, so I
am guessing that it is systematic rather than chance, but it would
be useful to have confirmation from other people as well.

Cheers,
David

Agree. Our collective experience seems to be that the two-PC approach is
best by
far, but one will work OK, though the lower spec the less can be done with
other memory-hungry programs without interfering with MSG-1 data.
Once anyone gets hooked I guess they will be saving hard for that second PC
(or,
I suppose, giving up all other activities on the one PC!).

Robert,

Thanks for your comments also.

Re: newbie setting up for MSG

David,

Thanks very much for your suggestions to my questions 'what do I need to do
what?'

It just seemed to me that there are many variations as to what is being used
currently for reception of MSG EUMETCast data.
Some are running 'high spec - do it all' systems some are fairly basic and as
you
and Arne have shown recently you can, given limitations, run a fairly
basically
specified system and get 'satisfactory' results.

It seemed to me to be useful to try to define a specification for a
'preferred' system.
I thought my survey would have given some pointers but I think it threw up so
many
variations that one couldn't see the wood for the trees.

Your system thoughts have made things clearer.

Regards,
John.


Mini scans animation

Just to say a huge thanks to David for the latest version of GSS - not sure if this note belongs here or in geosatsignal.

I was so glad I had saved a morning of the 5 minute mini-scans. Awesome is about the only word I can use to describe the feeling I had when I looked at the clouds lazily building and moving across the African interior. In a way it was quite an emotional moment to look at the beauty of our planet in such detail and with such frequent frame updates.

It shows again what amazing possibilities MSG-1 is capable of, and thanks to EUMETSAT for the trial.

archive?

Robert Moore
 

Dear All, the sheer volume of MSG-1 will raise archiving problems, especially
for those who may discover they need to go back to earlier data. I don't know
EUMETSAT's policy on archiving. I have written a short note on the problem
which I will submit to RIG journal.

Alan - thanks, if you are on broadband could you send me Ch 12n 1400 - 1700, on
each hour? David has supplied Ch 09 for those time already. If you don't have
broadband I can send you my postal address for a CD. Great, thanks again.

Robert,
I have .jpg files of channels 1,2,3,4,6,9,12,12n from 1330 UTC onwards
until 1715 when it is only channels 4,6 and 9. Let me know what you want and
I'll see if I can burn a CDROM, unless you get a better offer who can
transfer with broadband.

Best regards - Alan

Dear All - have any of you, by any chance, an archive of the HRV or other

period would be most welcome.

To a good approximation, yes. The file should be calibrated
correctly for GeoSatSignal - I'll send you the mid-day image to test.

Hello,

This email message is a notification to let you know that
a file has been uploaded to the Files area of the MSG-1

File : /20031213-cloud-pic.jpg
Uploaded by : gm8arv <david-taylor@blueyonder.co.uk>
Description : Robert Moore comments: At 1115 this morning (13 Dec 2003) there was a black cloud line across my northern sky with a band of blue below it (20031213-cloud-pic.jpg). This feature was clearly visible in the 1115 HRV image (20031213-clouds-MSG1-HRV.jpg). By 1200 we had mainly blue sky, which by 1300 was horizon-to-horizon. This change could also be tracked by MSG-1. Nice to see from below what we so often only see from above!

I have all of channels 2 and 9, saved as JPEG. 192MB total. I
don't keep HRV images that long, and I don't normally keep raw data
at all. (The recent mini-scans were an exception - but even taking
only a few channels it required two DVDs to archive the data).

Re: MSG data access.

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

I'm delighted and proud to announce changes to EUMETSAT's MSG Data
Access Policy which I have been striving for, for many years now...

John,

Could I add my personal thanks to those you have already received
for the work you have done in this respect?

I know that dealing with such organisations is not easy, as they
have defined ways of working, and you have to fit in with those ways
or you make no progress at all. Things can seem to move very
slowly, and it does not help to try and force things along. Many
within the organisations genuinely do their best, but this is not
always visible to outsiders.

I have said before that I think your patience and political skills
in dealing with these issues are unmatched, and I am delighted that
the amateur community has been able to benefit from your talents!

Many thanks,
David

Re: Nexus card

Bill Maddox
 

Thanks for the response but my card died a death last night :(
While I'm waiting for a new one or a repair I went and bought the
new Hauppauge Dec3000-s. So far my testing has shown it to be a
little faster for my downloads on SAT@Once, used to have to wait
hours before i had anything worth looking at.
Looks like I will go ahead and register for msg-1 and start getting
some decent images, I'm used to the gray grainy sort :)

Again thanks for the info

Bill

Re: twin ?

Fine, Arne and David, that solves the problem. Two cables from the
dish on the balcony, (without decreasing signalstrength)one for the
comp. one for the sittingroom.
Saw your pic on the list Arne. Will use that in the future as well.
As always mny tks you both, gr, Ap

Arne, Ap,

I may have confused things - by twin does Ap mean an LNB with
two
outputs? If so, my comment about signal strength was wrong.

I had thought that he meant two offset LNBs looking at a single
dish, so that you could view both Hotbird and, say, Astra at the
same time. That way you keep both the family and the MSG-1
enthusiast happy with just one dish on the house!

Right David, all these terms are confusing.

I (and I gues Ap also) use a single LNB equipped with dual output
(2
f connectors) This way you can connect two receivers to receive
from
the same dish/direction. The receivers can switch independently to
Horizontal/vertical or high/low band without interfering. If you
use
a 2 way power splitter to "divide" the signal from a single LNB
with
single output, the LNB can only be used in one band and one
polarisation.
Quad/eight output LNB's are also available if you think of sharing
Hotbird with your neighbours !

And to make it more confusing I have a dual LNB setup, both with
dual
output. This makes it possible to connect two receivers to Hotbird
(center LNB) and also have two receivers on Astra (offset LNB.

Be aware that you do need 4 cables this way !
Advantage is having to place only one dish, giving Astra and
Hotbird
TV simultaniuos with MSG data !

Look at the image 80cmMSGdish.jpg in the files area, this is my
equipment just after install, using one single output LNB and one
dual output LNB.

Re: Nexus card

Luca Bertagnolio <lucaberta@...>
 

Bill,

I have successfully used an Hauppauge WinTV-Nova card during the
summer. Make sure you have the right driver from the Hauppauge
website (probably Hauppauge UK or Germany is better than US, as DVB
is not yet too popular in the US). Your card is much more
sophisticated compared to the Nova, so you will only use part of it
with EumetCast.

Tellique does not talk directly to the card, it uses the standard
TCP/IP driver to do that. You will then need to make sure the card
has the appropriate virtual Ethernet driver installed, and that the
IP address is configured as 192.168.238.238.

Let me know if you need further help.

Bye, Luca
