I reset the processing computer a short time ago, after leaving the
receive computer to accumulate files, and all now appears normal.

Phew!

Running two file eaters is not recommended! Maybe I need to code
against this?

Do you think this may have been the cause of your problems in the
past?

Possible explanation for strange event

Lawrence <lawrence@...>
 

Hi David

I think I now have a clue about this mysterious event. As mentioned,
the images were simply falling apart. Earlier today I remember noticing
that MSG-manager had disappeared from the screen. I had not actually
switched it off - you cannot do this by accident. After checking, I
started it up again and left it. Later I noticed the holes. Perhaps
somehow there was a second copy running unseen and therefore deleting
the files.

receive computer to accumulate files, and all now appears normal.

Phew!

The message below from Eumetsat explains why the 12.00 and 15.00 FSD
products were all in so quickly. For a moment I thought Eumetsat had upped
the bandwidth of Data Channel 3 !

Re: Possible new problem

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

In fact, all files coming in through TQ were *deleted* on
reception - even though the MSG-manager was off. To check that
there wasn't a different effect, I did a virus check of the receive
computer - it was clean. Files were still getting deleted so I
physically removed the network cable - and the deletions then
stopped.

Where I go from here, I don't know. Holes are in all my images.

Lawrence, it sounds as if:

- there is another copy of the MSG Data Manager running somewhere,
perhaps on another PC

or

- the first copy of the MSG Data Manager did not shut down
properly. Is there a second process named MsgDataManager visible on
the Task Manager Processes tab? This does sound unlikely, though.

Did you check the reporting level and buffering options in the
Tellique recv.ini file?

For what it's worth, no missing segments so far today, we even got
midnight Meteosat-5 data!

Cheers,
David


Possible new problem

Lawrence <lawrence@...>
 

Today has not been brilliant on the MSG-1 processing front. I have lost
so many segments that I activated the signal monitor - it showed 50%
which, although slightly lower than I can get when I work on it; the
error rate stayed at zero.

I switched off the processing (using the stop switch) because I was
viewing a DVD (astronomy stuff). When the session was over, I
re-started MSG-1 manager but was puzzled that only a couple of real-time
files were processed. I am used to the backlog waiting. Curiosity led
me to repeat the experiment - switching off the manager and watching
what happens. In fact, all files coming in through TQ were *deleted* on
reception - even though the MSG-manager was off. To check that there
wasn't a different effect, I did a virus check of the receive computer -
it was clean. Files were still getting deleted so I physically removed
the network cable - and the deletions then stopped.

Where I go from here, I don't know. Holes are in all my images.

BTW David, I have *no* reason to believe that this is a bug in MSG-1, I
simply don't know what is going on here.

Data for this morning (Dec 05) was stamped 0000 today, so it should

May thanks, Eumetsat.

Same over here Douglas. Up to cycle 2030 this is my only missing

But I do have this "log_file=>>recv.log" entry in my recv.ini
Must have been somewhere in September that I read this tip on the

Re: Met-5

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Beginning to wonder if this old satellite is developing problems. Once
again
the 15.00 UTC visible is degraded and all three images this morning at
9.00
UTC had a nasty horizontal line through them. I assume it must be
scanner
problems.

Ian.
Ian,

Well, on the Dundee Web site, the images for 14:00, 15:30 and 16:00 are
fine:

http://www.sat.dundee.ac.uk/pdus/XV/200312041400XV3_g.jpg

etc.

so I would suspect it is the ingestion or processing for MSG-1, rather
than the scanner on Meteosat 5. (Yes, I realise I am a cycle or two out,
but the last time there was a similar problem I checked the PDUS data from
Dundee for the same time slot and it was fine as well).

The horizontal line may be no more than a bit of RF interference or
whatever between Meteosat 5 and the receiving station. It is also present
in the Dundee image.

Cheers,
David


Re: Those missing segments

Douglas Deans <douglas@...>
 

So far today I ahve had one missing segment on the main PC, 1445,
HRIT ch 10, seg 4. The Transponder Status screen shows no
uncorrected blocks, and there is nohting like a bunch of missed file
messages in the Tellique log file. Why that segment is missing I
have no idea.

Yes that is my only missing HRIT segment reported for today (since 07.30).
So probably not us.

*not* other programs starting up and hogging resources. I guess I
simply have to live with this.

Lawrence Harris
Lawrence, I don't believe it is my software that is causing the
problem, either. I will reply to you on the MSG-1 list.

Cheers,

I am still uncertain as to where the problem lies. I have a system
here that, under normal circumstances, doesn't loose segments. I
have seen a very occasional loss (say every other week) which I
could ascribe to the weekly defrag run on the disk with the Tellique
log files and staged MSG-1 data files. However, over the last few
days the system has been loosing a few segments a day, whereas a
second parallel system did not. This is similar to what other
people have reported - sudden unexplained losses of segments.

On checking the Tellique log file, I found that there were an awful
lot of "Missed file" messages around the period in question. I
understand this is normal, and refers to LRIT data which has been
interrupted by higher priority LRIT data, forcing the waiting files
to be transmitted later.

However, I did wonder whether all the activity of writing to the log
file with all these "missed file" messages was actually then causing
a data loss. Note that compared to Eumetsat's current standard I
run without the log file buffering enabled, and with verbose rather
than normal logging, so I may be creating problems for myself. I
have now turned on the log file buffered writing in the RECV.ini:

[locations] section: log_file =>> recv.log

So far today I ahve had one missing segment on the main PC, 1445,
HRIT ch 10, seg 4. The Transponder Status screen shows no
uncorrected blocks, and there is nohting like a bunch of missed file
messages in the Tellique log file. Why that segment is missing I
have no idea.

Suggestions:

- you may want to look at the log file for the period where you have
missing segments.

- you may want to run the Transponder Status screen looking at the
SNR and in particular for any uncorrected blocks. Warning, some
people have reported that this _causes_ missing segments.

- you may want the change the Tellique logging level and turn on
buffered log file writing.

- check if anything is blocking the satellite signal - aircraft,
birds, trees etc. I hear it is windy down south today - is your
dish absolutely aligned and steady?

Going back to my original comments about "missed files", I wonder
what it is that has to be given priority on the LRIT channel? I get
the impression that the LRIT channel is heavily loaded - could
Eumetsat purchase a little more bandwidth for it to reduce that
loading, and hence the congestion causing these file re-
transmissions. Just thinking aloud.....

Cheers,
David

why is it important to separate them and could someone send me a
copy of a correct .ini file?
Paul,

There is no need to separate them if:

- you process and delete the data right away (e.g. with the MSG Data
Manager)

- you turn off the data you don't use (e.g. ATOVS data on Data
Channel 1 - remove the PID 500 [0x1F4])

Otherwise, unless you are using NTFS, you will run up against the
limit of the number of files in a single folder, and in any case,
having too many files makes for poor efficiency.

Cheers,
David

I am now receiving data,a reinstall of the software cured the
problem.
All the data gos into the received folder,i have tried to edit the
recv channels.ini file by adding the lines of text that are in
eumetsats help file but i cant get it to work.

I noticed from previous posts that there was a copy of a .ini file
in the files section on here but i guess its been removed.

why is it important to separate them and could someone send me a
copy of a correct .ini file?

thanks for all your help

Meteosat-5 - midnight slots

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Folks,

Eumetsat has started sending midnight slots for Meteosat-5 but,
unlike all other satellite data, it is stamped at 2400 for the day
before rather than 0000 for the current day. I have asked Eumetsat
if it might be possible to rename the data so that it conforms will
all other HRIT/LRIT data, but I don't knwo if they will do that.

Of course, 2400 is an invalid time (2359 is the latest minute), so
the current MSG Data Manager will reject this data. If anyone is
desparate, I have a version of the program which allows the 2400
data, timestamps it to 0000 "+1 day", but still saves it as "2400".
Before making any further ad-hoc changes I want to see if Eumetsat
will fix the problem.

Cheers,
David

Hi Douglas

I received my software before i got my dvb receiver so i installed
it first.I did have to manually edit the recv.ini file.i have just
uninstalled and reinstalled the software, this time i did not have
to edit the ini file.Also noticed that in the recv.ini file it says
user_key_crypt so i guess its been encrypted because its now
different to the key i entered on the first install screen.

I will let you know what happens.I need to test it at work as i dont
have a dish at home yet.(very high back to back terrace facing wrong
way)

Paul

Hello Paul. Two things to mention. My Tellique software is old
but my
brother has a more recent version. He did not need to manually
edit the
recv.ini file (as I had to do) as it was prompted automatically
during the
program loading.
Secondly, if you bring up the html shell page (right click on the
purple
icon in the taskbar), select Licence from the menu on the left, is
there
under client identification a string of numbers and letters beside
host_key_1, 2 and 3.
