Date   

Smallest portable EUMETCast receive and decode system will be shown at GEO symposium

a_van_belle
 

At the GEO Symposium I will demonstrate how you can receive and decode
EUMETCast using a netbook PC and USB receiver.

The single system does not only receive MSG HRIT, Rapid Scanning Service,
FSD, AVHRR, MetOp and MODIS data but also decodes and displays most of this
data real-time. An animation based on 5 minute interval Rapid Scanning
images is also shown.

The complete system runs over 3 hours from battery. Runtime can be extended
using an external 12 Volts battery or by connecting to your car's battery.

This is the ideal setup for holidays as long as you are within range of
EUMETCast / Eurobird9.



Full details will be shown at the GEO symposium held this Saturday May 7th
at the National Space Centre in Leicester !

See http://www.geo-web.org.uk/





Greetings, see you at the Symposium.

Hello.I'm new in eumetcast . I want to fill the first membership form in eumetcast site. Will I limited in using all the services, If I choose amateur usage in the form ?
Thanks
Welcome to EUMETCast and to the group!

You will find some guidance here:

http://www.geo-web.org.uk/eumreg.html

although the screen-shots may not match exactly as the form keeps changing! As an amateur, you have access to almost all the data, except that marked for National Weather Services exclusive use.

Ask here should you have further questions.

Cheers,
David

100 days uptime without packet loss

ernstlobsiger
 

Dear Eumetsat
Dear all

Just a big thank you to Eumetsat that managed to improve the EumetCast uplink chain that gave us a couple of simultaneous lost packets all over Europe in the past. This effect seems to be gone since mid January 2011 about when I installed 2 APC Smart UPS for my EumetCast receivers.

An here comes the publicity part: For the last 100 days both my GNU/Linux receivers have not lost a single packet. So another thank you to the community that keeps up making and improving Free Software.

Cheers
Ernst

Re: occasional red T icon

I had not realised that once you get the red T, that reception was
permanently stopped. If the RF level and frequency still look to be
correct, it could be a network issue - check with a PING 192.168.238.238.
Thank you this ping tip. I will check it in the next red T occasion.


On an 80cm dish here I see about 63% quality, and 8.3dB SNR. Your 54-57%
sounds a little low (as does mine), and you can compare with others here:

I have just a small dish, because the old bigger one was broken by stormy wind. (and I have also a stupidly set extension cable which obviously decrease the signal quality.) Anyway. It is working OK.

Hello Ian,

Yes I had a reply when I got back in today:

'We had a problem with the server over the weekend, the server has now
been restarted and the files are flowing.'

Still no filter on the out of area files though.

Here are my statistics (in a few hours period):

Received Packets on Data Channel: 1653936
Missed Packets before FEC: 40
FEC Recovered Packets: 31
Received Bytes on Data Channel: 1934612000

So I have some missed packets, but otherwise I have not experienced problems with the received images (at least with those ones which I regularly checks) (until T goes red, because from that time no more received file.)
I have 54-57% signal quality in setup4pc.

Korn�l
Korn�l,

Difficult to make a judgement - if that was a receive-only system running XP then I would expect zero missing packets, but my dual-core Vista system with the DVB World box gets about 10 missed and 10 recovered per day. I had not realised that once you get the red T, that reception was permanently stopped. If the RF level and frequency still look to be correct, it could be a network issue - check with a PING 192.168.238.238.

When you look at the TelliCast HTML shell, Statistics, do you see:

Missed Packets before FEC: 0
FEC Recovered Packets: 0

If you don't have zero packet loss (or at least all missed packets
recovered), then you will get missed data, and hence the "message lost"
reports. Getting missed packets down to zero can be more of an art than a
science, and entails careful configuration of your PC.

I recall that when running Setup4PC a second or third time it may not show network information, I would not worry about this.

When you look at the TelliCast HTML shell, Statistics, do you see:

Dear All,

I have a new reception PC (windows 7 with RAMdisk). Generally it works
very well.
here some more info:
http://mrstratus.blogspot.com/2011/03/my-new-eumetcast-reception-
station-at.html

the only problem which fortunately appears very occasionally (every 2-3
weeks for example) is that T icon turns red. In this situations only the
complete restart of the computer will help.
[]
What should I checked at that time when I see the red icon?
I would suggest checking what the TelliCast log file contains.


The received files and also processed images are written to an USB
harddisk, because it is quite noiseless. (my main harddisk is SSD, it is
better not to write on it a lot.)

I just noticed that my USB disk is FAT32 and not NTFS at the moment. I
will change it if it is really important...


Thank you for your advices.

Kornél Kolláth, Hungary
Kornél,

The data transfer rate on a USB hard disk may be marginal. I would try
and have the &#92;received&#92; directory and the processed images directory on
two physically different disks, if possible, or make a very large RAMdisk
to hold the &#92;received&#92; directory. But neither of these steps are required
unless you are suffering from missing data during reception.

I would normally recommend NTFS particularly where directories are
expected to hold large numbers of files, but it could be that FAT32 is
slightly faster - I haven't done any direct comparisons here.

Cheers,
David

Hello John and David,

Even with all software up to date, it is recommended to check your received folder at least once a week.
There are so many data selection options in MSG data manager, you can easily have overlooked one.
And we occasionally see new or trial products accumulate here.

About your temp files, these are failed attempts to compose a file from the FSY files. No space left on your hard disk could also cause this.

Greetings,
Arne van Belle
Actually, with recent versions of the MSG Data Manager there is an option to automatically remove unprocessed files from your &#92;received&#92; tree. On the Setup tab, Options, File controls, RX disk space control, just select a non-zero value for Auto-clean minutes. I would suggest a value of 480 (8 hours) for folk who run on a daily basis, and perhaps 1440 minutes for those on 24 hours a day. The Tools, Housekeeping report menu has display where activity from this option can be seen in the lower panel.

You can also my TrimTree program to clear out many directory trees on the basis of "delete files older than N days" - it's a free (but unsupported) program available here:

http://www.satsignal.eu/software/disk.html#TrimTree

Add it to your night job or login job.

Cheers,
David

David,

Thanks for the advice regarding both problems.
I somehow thought it was a matter of 'you haven't updated your software.'
Some of us never learn?!

I do see the regular notifications of updates from you on the groups but
.....

If the RAMdisk is near
full, and it's otherwise convenient, I would stop TelliCast, delete all
temporary EUMETCast files, delete the *.FSY in the RAMdisk, and restart
TelliCast.
This route sometimes works for me to restore my RAMdisk capacity but often
seems reluctant to 'start up' again.
I find it quicker actually to just close everything down and restart as
this clears the large fsy's and resets the RAMdisk.

Thanks again - off to update and delete unwanted files.

Regards,
John




Re: Missed messages?

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

All,

Having experienced several gaps in HRIT and AVHRR data this afternoon I
'went looking' and found low Ramdisk capacity - which is usually a suspect.
But also I found a rather large received folder - 733 MB's.
And the temp folder full of empty and 'filled' files.

The files in question in my received folder were:

L-000-MSG2_-MPEF_____-FIRC____000001 plus a date.

These seem to have accumulated since March.

In my temp folder there are many files such as:

4c8fc .....
4c922b .....

Most are 0 KB, several a couple of hundred KB and some many MB's.

Er, they are not much good sitting there clogging things up.

Regards,
John Tellick.
John,

I'm on limited and intermittent access right now, but in case no-one else has commented:

- please keep up to date with the current MSG Data Manager:
http://www.satsignal.eu/software/msg_dm.htm

- please add yourself to the e-mail notifications for updates at the bottom of this page:
http://www.satsignal.eu/software/updates.html

I'm sorry that you missed the announcement, which was on several Yahoo groups. I try not to e-mail users directly, as some would regard it as spam.

Delete the temporary files older than one day. If the RAMdisk is near full, and it's otherwise convenient, I would stop TelliCast, delete all temporary EUMETCast files, delete the *.FSY in the RAMdisk, and restart TelliCast. The temporary files are from incomplete data transfers.

David
