Hello Peter,

It's not just size that counts! It's disk access times and buffer if you
are not running a RAM drive. As David has said elsewhere a disk with
less than 100GB is quite satisfactory under most conditions if you have
a two computer set-up and are not planning to leave data unprocessed..

As to the processing side - how long is a piece of string? - How much
data do you want to archive or keep for periods. It all depends on how
much data you are accessing and processing. You could easily get 10Gb a
day of data with the basics for example. Then again you may want to
store other files created by some of the imaging software, albeit these
will be of lesser size.

Also make sure you have the appropriate file retention settings in the
data managers to ensure you don't use up all the space on a disk!

Cheers
James

Hi all
thanks for reading this Post:
I'm new to getting data from Eumetcast . Im going to get the data in the first place over the internet FTP.
Need advice as to what would a good computer to start with getting the data from FTP then to be able expand into direct data from the satellite.
any ideas or info on setup and hardware would be great

Re: Eumetcast channel 12 fire images

The Eumetsat Channel 12 data which is saved in MSG-1/Images /Fire (MOD14) can be opened by David's ModisL1 Viewer.

Hope that helps.
Ian.

Hello,
Thank you all for your kind replies re my previous query.
Yes I do refer to the Eumetcast channel 12 data.
I now find under MSG-1 images fire some MYD and MOD data - yet I am unable to open these.
Kindly advise with which programme/s I could manage to open these files smoothly.
Thanks in advance & regards.

Hello,
I wonder if the use of MSG D.M. allows still to see fires in
Spain/Portugal.
Although I think I ticked all relevant boxes and set D.M. to show
channel 12 fire data I am still unable to see any fires there.
I would be most grateful for any hints how to overcome this problem.
Thanks in advance & regards.

Just in case there is any mix up (and some of the replies suggest there

Hi Rob,
Unfortunately xrit2pic doesn't work on our systems (linux library issues)
so I can't give this a go.
But luckily I have found a solution to my problem, so no worries.

Thanks for the suggestions!

xrit2pic can add lon/lat lines, also called in a script. So you don't
need the gui. Output can be pgm/16-bits or 8 bits or jpeg; input are the

FYI there's a significant fire in Trinidad (I think) at the moment, it's
visible in the low-res MSG data and - once the window slides over - should
be visible in Ch12 also.

Re: Skystar S2 windows 7

Bonjour Alan,

I think it's probably the biggest problem. I will try working with the S2 card till tonight, and if I can't manage to use it I will buy a new one (Skystar 2 or Technotrend).

Thanks for your concern.

Cordialement,

Caroline

Bonjour Caroline,

I hesitate to join in this as I don't have confidence that I understand
what is involved, but it seems to me that part of the problem may lie in
the fact that the card being used (S2) is designed to work with a
different transmission standard than that being used by Eumetcast. The
S2 card is meant to work with HD signals as compared with the standard
definition signals of DVB-S or T. To do this, the signal uses a
different forward error correction (FEC) arrangement which gives more
powerful error correction: a modern large LDPC code is concatenated
with an outer BCH code to achieve quasi-error-free (QEF) reception
conditions. While the S2 card has some backward compatibility
capability, it is not clear that it can work with the signal formats
used by Eumetcast.

I would suggest changing to a card like the skystar 2 which is known to
work, or one of the newer USB boxes.

Some mainboards can't provide enough power to the Skystar card (also
driver-dependant!). Then, a different slot might help too. Set BIOS and

I can see the radio programs without any problem, but I can't see the TV programs. I'm focused on Eurobird 9E.

I will see the BIOS and then tell you if the system works.

Dear all,

I'm new on this group.
I am trying to receive MSG1 and MSG2 data with the Eumetcast system.

The system work normally (the satellite signal is ok, the tellicast icon is white and pink), and I receive data normally till a certain time (sometimes short (2 minutes), sometimes longer (2 hours, one day,etc.)).

After this point, the number of missed packets before FEC increase (2000, 5000, etc.) as the FEC recovered packets (20, 100, etc.) but the number of FEC recovered packets is far below the number of missed packets. And then at one point the system stop working. There is no more data channels available. The satellite signal is still ok and so is the tellicast icon, but no more data is acquired. I have to shut down and restart the computer to have new data.

I mailed the OPS and they told me my DVB card is not the one recommended as it is Skystar S2 and not Skystar 2 TV PCI.

Has anyone had the same problem as I have ? I should specify that I'm on windows 7.

I should specifie that I am near an airport, that sometimes people may pass in front of the satellite dish, and that a crane is far enough, but in the axe of the satellite dish for some time, and that all of it might disrupt the signal.

Best regards

Caroline


Re: Skystar S2 windows 7

deforeitcaroline
 

Dear James and David,

thanks for your fast answers.

I already tried with only one channel, but it still didn't work. I didn't use Ramdisk so I will try it. I will tell you if it works.

Thanks a lot.

Regards

Caroline


Hello Caroline,

I agree with what David has written - I use to have the dish at ground
level and occasionally when we needed to move in front we of course got
the missed packets.

This may well be the major cause - specially if then there is a backlog
of data with errors.

I use one of David's nifty little programmes - Trimtree - which allows
you to look at a directory and specify data which is older than a
prescribed date and the prog will then remove it. You could run this
using Windows scheduler - say every hour for data older than an hour,
unless you are only processing data a couple of times a day.

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

I also use a RAM drive and use the clean out to remove files that may
have become occasionally orphaned through data corruption.

Hope that helps if the problem is not the card.

Cheers
James
