Thank you very much Ernst,

So it seems that my LM is ~ 3.1-3.5 for basic service and almost 0 dB for HVs-1, less than what Eumetsat recommends but it works for basic.

The first thing to do; enhance the pointing of my dish (1.2m). I will stay on TBS-IP Tools, it works for me.

Thank you again for these explanations and recommendations.

Best regards

Youssef,

I never had a Windows receiver. If TBS IP-Tool works for you stay with it. A couple of people including David
have reported "Blue Screens Of Death" (BSODs) with TBS IP-Tool and have changed to CrazyCat's solution.
Others have not seen BSODs and were happy with TBS IP-Tool (seems PC harware and version dependant).

Youssef,

with SNR 9.0 - 9.5dB you cannot receive HVS-1. EUMETSAT says you should have 4dB link margin (LM) for good reception.
LM depends on SNR and MODCOD used. I apply these formulas in my monitoring (also hard coded in Ayecka SR1 firmware).

Basic service:   MODCOD = 8PSK 3/5,  LM = SNR - 5.9 dB
HVS-1 service: MODCOD = 16APSK 2/3, LM = SNR - 9.3 dB

This shows you have around zero link margin for HVS-1. With my proposed SNR of 12dB you get LM = 12 - 9.3 = 2.7dB.
Not exactly 4dB as proposed by EUMETSAT but it will work with then and when HVS-1 UDP packets or even files lost.

Below is what I have with a 1.25m dish on a rather rainy day. HVS-1 reception is possible with a well aligned 0.85m dish.
Aligning a dish is an art in itself. A good start is using the sun for azimuth (a magnetic compass is no good). Also check:

Hello Ernst,

Yes, I am using TBS-IP Tool.

Concerning the SNR, I think it’s less, usually around 9-9.5 according to the TBS interface. Concerning the MOCODEs, I selected all the modes to avoid any filtering.

Yesterday I received some data during 5-10 minutes and that’s it. After that it stopped, I thought I made a false manipulation.

Thank you for the reply, I think I should first fix better my dish.

Do you think it’s a good idea to use CrazyCat's BDA-DataEx? Any advantage?

Best regards

Hi Youssef

Do you use TBS IP-Tool or CrazyCat's BDA-DataEx?
Do you have enough SNR (it shoud be 12dB or above for HVS-1)?
Are you sure you have no MODCOD filter set (that prevents HVS-1 trafic to get through)?

Regards,
Ernst

Tellicast

Youssef Bennouna
 

Hello everybody,
I am trying to get data through TSL-HVS1 but the tellicast stays in the "connecting" state. I receive data through Basic service normally.
I checked the *.ini files, I also compared the bas*.in to *.hvs-1.ini, found nothing. As I am new to the Tellicast system I am not sure about parameters like "max_memory_usage", parameters like "receive_buffer_size"....
I am using a TBS 5927, I have a RAM disk of 500Mb on my computer (Windows10).
Can someone show me a way to debug this problem? or maybe send me a sample of the config file?
Thank you for any help or idea.
Youssef


Eumetcast HVS-2 tellicast .. red icon...help please

Philip Robinson
 

Hi
I hope someone can help as ive forgotten how to resolve this problem

On starting tellicast hvs-2 i have a red icon bottom right  of screen
Checking the log file it seems to be something to do with the announcement channel
the log file error shows
Failed to open announcement channel `TSL-HVS-2` address 224.223.224.223:4711 (Bad interface address)

i am sure its something simple i have to do, but my memory has let me down on this one. I am sure that  i have fixed this sort of problem in the past

hope someone can help
Philip
thx


Re: EumetCast server receiption stations monitoring with Zabbix

Ernst Lobsiger
 

Hi

No one here has AFAIK used Zabbix that seems to be an overkill for monitoring EUMETCast receivers.
Windows users with TC monitoring have MRTG running and there is much documentation on Davids site.

http://www.satsignal.eu/mrtg/performance_eumetcast-europe_link_margin.php

On my GNU/Linux TC receivers I use eLuna/RRDtool with graphic output via Apache2 (no SNMP though).

Hi

 

I was wondering why my signal was getting stronger.

I was usually getting 11.3db and now its at 12.3db

Hope it keeps like that

Ian,

 

Just logged on to my email's and I was about to comment on this first and then saw you post.

 

Yes, I'm afraid 'someone was obviously listening?'

We should have kept quiet and hoped 'the powers that be' didn't notice they were pushing out too much power.

At one point yesterday I was down to 13.3 dB - from 14.00 dB.

 

Hey-ho.

We've had these brief periods of 'increased' SNR before.

But I've never seen it this high since the good old days some years ago before the two (three?) step reductions we've had over time.

 

I'm looking forward to the parallel running test period of EUMETCast from Hotbird in a weeks time to compare the SNR on TP 1.

 

Regards,

John.

 

++++++++++++++++++++++

 

Spoke too soon John, as sometime earlier today the increased signal I

had been seeing vanished and signal levels back to where they were.

Unfortunate as I need all the signal I can get up here.



Regards
Ian.

Re: Tellicast Losses

Hello Ian,

Good to hear you are seeing and improved signal up there in Scotland.

I should have said that my SR1 Power reading remains at - 25 dBm 'despite' the increased SNR.

My SNR was steady at 14.00 dB till around an hour ago and is now 13.8/9 dB.
Ooops, just stepped briefly to 13.7.
But 'sun is up' and atmosphere active.

Mmmm, and Power stepping to - 26 dBm every now and again

As you say, let's hope it continues - I mean the increased SNR.

+++++++++++++++++++++++++

John I am seeing an increase in signal since yesterday as well, up about

0.3 SNR. When others reported a signal increase recently, I had not seen
any increase, so this is very welcome and let us hope it remains.

Although it varies depending the time of day, I am now seeing a signal
of about 13.3/13.4 SNR with a 1.1 metre dish which is pretty good this
far north in Angus.

Regards
Ian.

Hello All,

Just looking around for the first time today - had a long online funeral to attend today.

Just seen both my TC BS and HVS-1 showing yellow.
BS shows 1 failed to open EUMETSAT Data Channel 2 at  12:01:44 today
And 3 failed to open EPS-15 at 12:13:05, 12:17:08 and 12:30:09 today.

I had reset my TC's on 27-04-21 at 14:26 and BS has 26561 Missed Packets before FEC - and strangely for my system - a lot of those recovered 24884.

Today HVS-1 shows 1 'failed to open' E1H-TPG2 at 07:48:49 today.

Again lots of Missed packets before FEC (since the reset a couple of days ago) 133893 - and again many (for my system) recovered 132248.

SNR 10 minutes ago jumped from 13.8 dB to 14.00 dB for a couple of seconds.
Back down to 13.8 dB at 16:41 UTC.

Regards, John Tellick.

Same here.  You can always check on the page:

Looks like the Meteor-M N2-2 data may be to blame.  I found a couple of
very large files in the TelliCast "tmp" directory tree.
