Reminder: uplink changes tomorrow - December 15
|
The uplink service for EUMETCast Europe will be handed over to a new provider in December 2022.
"The contract with the current provider of the EUMETCast Europe uplink service ends on 31 December 2022. The handover to the new provider is scheduled to take place on 15 December. "This should be transparent to users and no change on user side is required. However, an interruption to the service is to be expected during the handover process. "Following the handover, the uplink to the transponder C4 on EUTELSAT 10A (E10A-C4) through which EUMETCast Europe is currently operated (for the Basic Service and High Volume Service 1 (HVS-1)) and to E10A-C3 (the new transponder for the High Volume Service 2 (HVS-2) – see related announcement) will be done from one of the new uplink sites (Fucino or Lario, in Italy). "The HVS-2 currently uses E10A-C10 (the second transponder on E10A) and will keep being provided by the current service provider till the end of 2022. "It is recommended that users check their reception after the handover." See: https://www.eumetsat.int/new-uplink-service-eumetcast-europe In addition to the interruptions, there might be a change in the signal level rebroadcast from EUTELSAT 10A.

Thanks for the reminder David. Do you think it is likely to be a morning activity?

Thanks for the reminder David. Do you think it is likely to be a morning activity?James, possibly yes. If it was me I would want to do things early, so as to catch the problems and deal with them that day. Or I might say do it last thing and let the problems come over night to be handled the next day! If it really was me I might do it just before lunch and have a splendid meal with a glass or two and let the afternoon drift away. Particularly if it was an Italian lunch. Or maybe get pizzas ordered in ready for an on-site bug bashing session! I have no idea, but 09:00 UTC is a popular time for EUMETSAT changes.

Do you think it is likely to be a morning activity?Update, Ernst and I got this request: "We will have some preparation activities starting at 09.00 (UTC) and the handover should be complete by 11.00 (UTC). Some interruption is expected during the handover, but it would be good if you could provide us some feedback on reception status and quality from your locations after the handover by email."

Glad all my monitoring was restored this morning so I can keep a check. JB On 14 Dec 2022, at 18:45, David J Taylor GM8ARV 🏴 🇪🇺 via groups.io <david-taylor@...> wrote: |

Some changes noted here. Basic and HVS-1 dropped but probably recovered. Sadly HVS-2 down about 0.2 as at 1008 but may well recover I guess.

Can't say that I'm saying the same pile of fully missed packets.
Definitely a lower SNR at the moment though!

I have now switched it off. Signal level is not bad (a few quick drop outs) but thousands of lost packets. Hopefully up and running smoothly soon. Regards, Douglas. |

If the handover has really been completed on time then I am disappointed by the new figures. Like you Ernst I saw the packet losses but HVS-2 has now lost about 0.7 compared to yesterday at 1131.

Hoping that you and David as you send reports later may be able to encourage them to review the levels. James. On 15 Dec 2022, at 11:04, Ernst Lobsiger via groups.io <ernst.lobsiger@...> wrote:

This is what I'm seeing. After change: C3: Level: -46 dBm SNR: 11.5 dB 11262.703 MHz C4: Level: -47 dBm SNR: 12.4 dB 11262.703 MHz Before change: C3: Level: -46 dBm SNR: 11.8 dB 11262.724 MHz C4: Level: -47 dBm SNR: 12.4 dB 11262.533 MHz Agreed on the link margin changes - very disappointing - but there's a new EUMETCast satellite next year! If you are seeing any TelliCast losses after 11:31 UTC I suggest you report them to EUMETSAT. I do see issues in the Europe-wide graphs and I've mentioned theses to EUMETSAT. https://www.satsignal.eu/mrtg/performance_eumetcast-europe_losses.php Cheers, David -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-taylor@...

Hi
I havent received any MSG4 images since about 10:30 this morning Has anyone else experienced this ? I assume its all to do with the handover today , I have many thousands of missed packets on BAS Kind Regards Graham |

I’ve had nothing today from about that time Graham – I originally assumed it was icing on the dish!

Hi======================================================================================== Graham, I suggest you close down and restart your receiver (if you have not already done that). That said whilst I am getting MSG-4 data in, for the first time in years I am getting losses in the basic service. I use the SR1 for that solely. There are also some issue with HVS-1 which I receive with a TBS5925 on a separate computer. Probably some teething problems but still disappointing. Strangely signal levels are good. Lets wait and see. Regards, Douglas. |

Hi Douglas
Thanks I had already done that and other data seems OK on HVS-1 and HVS-2 Its just BAS that seems to have problems Kind Regards Graham |

Hi Ernst
Are you seeing a large number of packet losses on the BAS service I just wondered if there are any changes I need to make to my configuration or should all just work eventually Kind Regards Graham |

Hi Douglas============================================================================= Graham it seems people are having different experiences, and none of them good. I have losses on Basic of about 300 an hour, a first ever for me. My HVS-1 is received on a separate computer using a TBS5925. I always have modcods on 'all' to avoid the TBS issue of moments of zero data which TBS do not deal well with. Now if I do that I get hundreds of missed packets per minute ! Using 16APSK2/3 gives me lost but recovered packets of about 30 per hour ... more acceptable. Still two services with perfect reception are now not working so well. Regards, Douglas. |

Seeing the packets missing across all three services here but it is recovering them. Going in cycles - guess things are being tweaked... Charlie |

Until today I had two of the finest EUMETCast receivers on the planet. I have shown that the TBS-6909X is capable of receiving four (4) full EUMETCast transponder without packet loss. Now it seems I cannot receive BAS anymore. I'll make my second report and then I'll try a couple of things. The problem might be a latency in the Uplink chain?! Regards, Ernst |

Hi Douglas
Thanks - I have emailed OPS The only things that are working for me are GOES16, 17, 18 and Him9 Apart from those - no images at all and the BAS tellicast keeps producing an Error I suppose all we can do is wait Kind Regards Graham |
