Re: Equipment for receiving MSG-1

Now, why would you want to run Geosatsignal (as well as MDM) - what is it and
what does it do?
Did you REALLY mean you are unaware of Geosatsignal John? Or are you only subscribed to the MSG list? I thought everyone on the list knew of this brilliant programme! I am amazed - but be prepared to be amazed yourself. Full colour animations using three of the MSG channels, overlays of Bracknell charts, temperature calibration read out, zoom in and out, the list goes on...

I think David might let you have a trial license if you want to dip your toe in.

Cheers,

James

Re: 'Overheating' SkyStar 2 cards.

John Parkins <john@...>
 

Hello john,

Sorry somehow managed to post this to the rig-l group first time
round.......


Well Technisat want to make their minds up.

"3. Now you have to choose a free PCI slot. If possible choose the PCI slot with
the designation ᅵ0ᅵ. (first PCI slot). So you make sure, that the board first will
be checked for functionality. Then place the SkyStar PCI in. Unscrew the
slotï¿œs metal dust protector located on the back cover of the case. Lay the
protector on the ground to one side."

I quote from Technisat own installation instructions, slot "0" being
the one next to the AGP slot........

So not always best to follow the instructions to the letter.

Now, why would you want to run Geosatsignal (as well as MDM) -
what is it and
what does it do?

I believe David's MDM now handles animation.
Are you saying that MDM's animation will cause problems with data
reception?

The MSG Data Manager handles animation with helper programs. There
is a choice of two optional add-on programs:

- MSG Animator - monochrome only real-time animations of selected
regions of the full-disk images. MSG-1 specific, and integrated
with the MSG Data Manager to achieve real-time operation.

- GeoSatSignal - false-colour, multi-channel processing from any
geostationary satellite, including remapping to standard map
projections (polar stereo, Mercator etc.), land-sea colour lookup
tables, and weather chart overlay. Not MSG-1 specific.

Do you (anyone) need to store 20,000 files of raw data?
MSG-1 produces about 15000 files per day, so if you want to
reprocess the data at all, that's what you need as your daily
storage requirement.

It seems from what Arne says that even the most powerful computer
today can loose segments if you make it do enough extra work. Using
a Pentium III 550MHz for receive-only, I have seen missing segments
with only slight extra loading. Even running Internet Explorer can
cause problems. On the other hand, running a disk defrag seems OK.
(Defrag does not use the TCP/IP stack whereas Internet Explorer
does. The DVB software uses TCP/IP internally. Co-incidence?).

As Dave says, there is nothing to prevent people starting with a
single-PC system, and migrating to two PCs in the future is that's
required. But adding Eumetcast reception and MSG-1 processing and
animation to a heavily loaded existing PC with too little memory is
not something I would advise anyone to do!

Cheers,
David

I don't know what your quest is here. Sam and I both run animation on a
single computer, and we could run several computers if we wanted to. We
choose to use one computer.

John, could it be, that you are still not receiving MSG at all ? In which
case why don't you telephone Sam or me, or even fellow RIG committee member
Mark Clark for some one to one assistance ?

Re: 'Overheating' SkyStar 2 cards.

Alan Sewards <alan.sewards@...>
 

I had occasion recently to switch my SkyStar card from one machine to
another. It had been running continuously for several weeks when I turned
off the machine and removed it. It was warm, but not hot, i.e. there were no
objects on it one could not touch. I have known video cards much warmer than
it was. So my card does not have an overheating problem. I did and do have
spare slots between the card and other cards - in fact, I put the SkyStar
card in a slot near the bottom as I felt that a cold wall next to it would
be helpful.

Re: MSG equipment survey.

johnrigsec@...
 

All,

Once again many thanks to the many users who have responded and please
forgive me that I have not got around to thanking everyone individually.

There are some interesting and I think useful bits of information coming to
light
and I'm quite surprised at the number of users using 2 computers.

Dave Cawley and Arne reminded me that memory speed is rather important in
the system - which I'd not asked for.
Also Dave felt FSB was important.

If you are receiving EUMETCast and have not responded to the survey - a
description of the reception equipment and computer/s you are using would
be helpful to get an overall picture.

Please e-mail me directly, rather than clutter up the user groups.

Re: Equipment for receiving MSG-1

Alan Sewards <alan.sewards@...>
 

David has made a good point here, and so has John in a related posting
(decide what you want from MSG-1 then choose the system to fit).
I have just changed my machines around with a dedicated wxsat machine doing
all MSG1 reception and processing on a 24/7 basis. It is networked to my
main PC which has GSS and all my other software on it and through which I
make my Internet connection and is only switched on when I want to play with
it. It is sheer joy to be able to fire up GSS and pick out the files of
interest from the wxsat machine through the network connection and play with
them without the machine being loaded down with MDM. That is the other side
of David's point - the conventional two-machine setup means that the main PC
is always on its knees with MDM doing decoding. If you have a two-machine
setup, try doing it this way - I'm sure you won't switch back!
(The wxsat machine cost me 500 Euros+OS, 2400Athlon with K7S5A equivalent
mobo and 512 MB PC333 DDR RAM.)

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

I have seen the postings regarding the lack of FSD imagery but I have also
not received any LRIT since the morning of Sept 22nd. Is this general? I ask
because I changed machines that morning and had to move the receiver card,
DVB software, tellqiue software and the rest, so there were plenty of
opportunities for things to go wrong at my end! Isn't it strange how things
tend to go broke at the sending end when one is making changes at the
receiving end!

Regarding Douglas' comments below, I appreciate that the OPS office is
likely pressed, but email is not the best method for letting people know on
a continuing basis, particularly when one has a 24/7 satellite channel at
one's disposal. Because I have only a dial-up Internet connection, I usually
only collect email twice a day, whereas I can click on the MDM Messages tab
anytime during the day if I suspect things have gone awry.

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 !

John, I believe a lot of people just look at the weather perhaps once a (work)day if the weather is a bit 'boring' as in the SE at the moment whereas if there are deep atlantic depressions or french thunderstorms or snow on the way then frequent images and animations are the order of the day. I tend to do this myself and I know of two keen Wefax people who have been put off at the thought of having to purchase a second machine. If one average spec machine is to be used to alternately receive files and decode/display them a useful utility would be an application that flags you when a sequence starts and when all files for that sequence are complete.
