Re: Extra files EARS/ATOVS -Amsua, Hirs

Yes I think it would be great if the file handling for the
retransmitted NOAA Amsua and Hirs files could be built in to MSG
Manager in the future to take care of all those files MSG transmits.
The ATOVs Reader is good for viewing but does not look after the file
handling at present.

It might be worthwhile to have an overlay option for putting ATOVs
image sections over HRIT images.

Cheers
Mark

David Taylor's MSG Data Manager does a thorough job of retrieving
HRIT, LRIT and FSD from my remote receiver PC and deleting them
when
decoded. Now, after about three weeks of operation, I'm left with
thousands of amsua, amsub and hirs files in the 'Received' folder.

Presumably this is image data. Could it be decoded into images?

Yes, you can use my ATOVS reader to decode this data. You can
write
a small batch file to move the data from the Receiver PC to the
Processing PC and decode it there. I am keen to make more us of
this data than just image decoding, and am looking for input. For
more information, please see:

Trial licences are available for the software. If you don't want
to
get this data, please remove PID 500 (01F4 hex).

I also meant to say in my previous mail that I receive quite a number of
e-mails direct. For example I received one from OPS this morning advising
me of the FSD problems and saying they hoped to have it rectified soon. I
mention this as I know some people do not get those messages. It was an
optional service offered at the time of registration etc. It's very useful.
My feeling is that Eumetsat are using this more to alleviate the engineers
workload.

Douglas.

Apropos of this, Eumetsat don't seem to be making any (or much) use of the
Messages capability in the MSG dissemination. What messages there are are
usually out of date, the standard one in the Admin Messages could as well
be
in the Timetable section, and there is rarely if ever any News. I get the
impression either that it is difficult to insert these messages, or that
the
mode of operation does not include sending out information via them. Be
nice
if someone thought about this!

Best regards - Alan
To be fair Eumetsat have a relatively small team working on this and I
suspect when they have some busy days (such as Monday and Tuesday) admin
comes second .... it is a trial and does not carry the importance (and
probably staffing) required by the 3 operational satellites.
But you are right the admin is helpful as we are also fine tuning our
systems and wondering if it us or them !

I wouldn't waste programming time, David, until you get a
definitive answer on this from Eumetsat.

Douglas.
Well, I couldn't let my users down, could I?

However, changing the program to recongnise those file names has
revealed that the images are incorrect. They appear offset to the
west, and the left and right parts of the image appear different. I
don't believe this is due to the program. I also notice a higher
rate of missing segments (on the MSG-1 HRIT/LRIT data) that I would
expect due to weather effects, so I would not put this one down to
my program.

I'll put the beta up on the Web site so you can see what I mean.

Is anyone else seeing a higher-than-expected missing segment rate?
(You can check today's data with the Tools, Missing segments
report... if you change the date).

Cheers,
David

Didn't they say that on the 24th there was some ground segment
maintenance work to be done? I hope it's more than changing the

FSD File naming change

Douglas Deans <douglas@...>
 

For some strange reason the 18.00 FSD files have been sent using a different
file naming convention.

Until this evening it was :-

GOES 10
GOES 12
GOES 9

This evening's 18.00 were :-

GOES
GOES
GMS

Not surprisingly David's software has not recognised them.
Is this a mistake... is it a new file naming convention and if so why no
announcement.

Regards
Douglas.

Re: Equipment for receiving MSG-1

While John is busy collating the inputs from those who have
participated in the MSG-1 dissemination trials, I thought it might
be of interest to question some of the basic assumptions. The main
one of these is that one needs to have two computers, one for the
reception function and one for the decoding.

One advantage of the two PC setup that no-one has yet mentioned is
that while you are out of the house, you only need leave the
dedicated receiver PC on, not your main PC. You can make that PC
remote, and even have a wireless LAN link to it! The Receiver PC
probably doesn't need as many anti-virus or OS updates as
your "normal" PC, so can have a longer up time.

One PC works, but it will not have the flexibility, performance or
stability of the two-PC system. Nothing to stop you starting small
and expanding as you can. You pays your money, and you takes your
choice, as they say!

Cheers,
David

Yes, there was an HRV segment which had been trucated when
transmitted. The MSG Data Manager, despite being written with
extensive exception handling, failed to pick up this bad data, and
gave an I/O Error 103 message. There is an updated beta version of

Re: Equipment for receiving MSG-1

Alan Sewards <alan.sewards@...>
 

Arne,
Thank you for this useful factual evidence. I do not have any results
with Animation running, so you have indicated an important load there. I
feel that using GSS or other software in addition to the processing load is
something that one would not expect the processing computer to do, I would
use another machine for that, but I feel that it is important to find out
whether or not a two-machine set up is essential for reception. I am now
more than ever convinced that it is not!

Best regards - Alan

I tested the single PC setup for a couple of days (and at our 13
september meeting at utrecht).

It is possible to receive and process images simultaneously. But you
need to monitor CPU load and memory usage at every step. Either
select only a few channels in MDM or stock up your memory to 1024 Mb
or more.
Running Tellique and MDM (all channels on, HRIT and LRIT) is possible
without missing segments on a 1.8 GHz P4 with 512 Mb.
In addition I do browse the images simultaniously wit PSP.

But running Geosatsignal and animation additionally is too heavy for
the amount of memory and causes loss of missing segments, even on my
intel P4 2.4 GHz with 1024 Mb DDR memory running Windows 2000 SP3.

But a word of caution here; MSG Data stream is still being expanded
(latest addition MDD data) and other "simple" tasks should be avoided
on this PC.
Once I tried to browse a folder with over 20.000 raw data files and
had Windows explorer hanging for a couple of minutes and a lot of
missing segments afterwards !
So house keeping a single PC that runs for 24 hours a day will be a
challenge !

Thanks David for you very fast reply,

Was completely focussed on managing my MSG equipment and did see the
thread on Satsignal too late ! Too many PC's running or to many
Mailing-lists ??
Have downloaded the update and will restart processing within a
minute !
