Re: Missing Segments

Robert Moore
 

Ian - I have not seen any missing segments today and I have been receiving all
day. I just checked back from now to 1600 (when I stopped working at my PC) I
found none in this block either either. Hope you soon sort it out!

Robert


Quoting Ian S Deans <ian@...>:

I take it others have seen higher than normal missing segments today.
Granted some have been on channels that I don't presently take. From 7.15
UTC to 20.45 UTC inclusive I count 23 missing segments on HRIT. I don't
normally have any problems with missing segments so hoping it is at the
Eumetsat end.

Regards

Ian.

I was out for a large chunk of today with systems off. However I can say
there were no missing segments between 0745 and 11.15 UTC on HRIT.

Would the system you propose provide access control? Would it
provide a low-cost implementation available under both Windows and
Linux?


Markus,

You seem to have avoided these questions. Eumetsat wish to use
eToken-based access control.

Eumetsat have stated that the present system will last for many
years, so you would need to be talking about planning for the decade
2010 onwards.

Cheers,
David

The public data should be available over the Internet so I feel
that
isn't really an issue.
It is, because the DVB Multicast is a much cheaper way to get huge
amounts of data. But I agree 100%, the data should be available over
the Internet either.


Would the system you propose provide access control? Would it
provide a low-cost implementation available under both Windows and
Linux? Who would provide the software support?
What I propose is the use of an open standard. Eumetsat could chose
between different vendors of commercial server software or make use
of an open source implementation and we could chose whether we would
like to buy a commercial client or be satisfied with whatever is
available. If they would make the data available over the Internet,
nobody would want them to use something different than ftp,http or
maybe scp.

Therefore wouldn't it be nice if Eumetsat would start transmitting
at least its public data with an open, standardized protocol? What
does this user group think about this proposal?

I've seen "Open Source" software projects before and, to be honest,
there end up being so many variants that support is a major issue.

multicast file transfer standard and open source implementation

mkempfde
 

Recently, I became interested in the reception of high resolution
weather pictures to improve the nowcasting of the weather for our
public observatory. Unfortunately, Eumetsat choose to use a closed,
non standardized protocol for the reliable multicast file transfer of
the satellite data. I was unable to find any documentation for the
protocols and data structures used by the Tellicast software. (btw.
if somebody is interested in reverse engineering it, send me a mail).
In some way, this decision was unavoidable, because there is no
standard for authenticated and encrypted multicast file transfer.
But, the IETF working group for reliable multicast transport
(http://www.ietf.org/html.charters/rmt-charter.html) has defined a
standard for reliable multicast file transfer over unidirectional
connections called FLUTE. Already, there are two open source
implementations available from INRIA
(http://www.inrialpes.fr/planete/people/roca/mcl/flute_infos.html)
and the Tampere university (http://atm.tut.fi/mad/).

Therefore wouldn't it be nice if Eumetsat would start transmitting at
least its public data with an open, standardized protocol? What does
this user group think about this proposal?

Re: Meteosat-5 problems.

johnrigsec@...
 

There were queries a while back about Meteosat-5 data and I checked the WEFAX
signal a couple of times.
Once it was OK, another time pretty weak then strong again.
I knew Meteosat-5 had a large inclination and EUMETSAT have given me some
more definite information.

Meteosat-5's inclination (daily travel N and S of where it should be) is 12.6
deg.
That is, it travels 6.3 deg. N then back to 0 then 6.3 deg S, back to 0 and
so on.

Currently it crosses the equatorial plane from North to South at about 07:00
UTC and
from South to North at about 19:00 UTC. This means that it reaches its
maximum
north and south travel at about 01:00 UTC and 13:00 UTC respectively.

What I didn't know was that these times change over a period of time.
The times move backwards by about 4 minutes every day as the Earth moves
around
the Sun, while the satellite orbit plane is almost fixed in an inertial
reference system.

Basically, in three months time, Meteosat-5 will be crossing the equatorial
plane from North to South at about 01:00 UTC and from South to North at about
13:00 UTC.

It seems likely that my signal problem is not antenna related - I can and
have adjust
the antenna elevation, but that the satellite probably drops below a distant
tall office
block at certain times of the day.

Something to check as an antidote to Christmas.

John Tellick.

Hello Nick

I am not sure where you got your information from but it is hardly
accurate. NOAA a.p.t. is set to continue for perhaps a decade, barring
a series of unexpected events. More NOAA wxsat are scheduled for launch
and, assuming that they don't drop any more, should see us well into the
next decade. Cut your teeth on a.p.t. if you wish, though currently,
setting up an MSG-1 system could be cheaper.

best wishes and welcome

I have to say that when I installed the latest version of the software
it put a shortcut to itself in my startup folder, so it starts

Re: Power on query

Ian S Deans <ian@...>
 

David and Lawrence,

I have never used a "settling down" time. Most mornings I switch on my
computer and walk away with the DVB card and then Tellique loading with the
start up ( DVB card loads first ) Some time later I then manually load Data
Manager and MSGAnimator and leave it to catch up. Although on a fairly low
single computer spec. I am one of the lucky ones in that segment loss (
out with Eumetsat problems ) has never been an issue. However if I use
Setup4PC to monitor signal level I am in big trouble, with serious segment
loss. Needless to say I don't.

Regards

Ian

Not until at least 2010, I believe...


Will this wonderful stuff run under Linux? There is a driver for
the technisat DVB card available ( I am sure I saw one somewhere in
the last kernel source I downloaded) however I'm not a bit basher!!

I saw somewhere that the teleque (sp?) software would run on 'all'
OSs including Linux

I understand there are still some issues with Telliqeue and Linux -
possibly the eToken support? See John Tellick's recent posting. My
stuff doesn't use anything special, so it should run under
Linux/Wine, but I haven't tested that.

In any case, Windows will be around for a long time yet, so I don't
see any reason to move, to be honest. In my tests, I have found
Linux to be a hotbed of incompatibilities compared to Windows....

Cheers,
David

Hi All,

I have just setup MSG PC with DVB card locked on

I used EUMETSAT documentation TD15 for setting up telllicast

Is there some genereic .INI files that can be used
for images reception from MSG ?

Many thanks,

I've often started tqrecv before the Technisat software has started. It
