Re: MTSAT and MSG LRIT

MTSAT were a series of Japanese owned weather satellites which are now discontinued. Himawari-8 is the replacement for MTSAT.
Meteosat LRIT images are no longer broadcast via Eumetcast as far as I know, though are available via their web service. They are only low resolution resampled versions of the HRIT images anyway.

David,

there was no date on the plot, that's why I asked. Your answer is good news again: It means that we now have good SNR on C4 (H) despite C3 (V) is active on the same frequency with even higher signal strength. So there is indeed hope for similar SNR values for what we usually call T1 (BAS + HVS-1) and T2 (HVS-2) after the switch in 2022. I'm somewat confused by John's measurements though: He finds lower signal levels on C3 (-35.3dBm)  than C4 (-30.2dBm) while your plot shows higher signal levels for C3 than C4.

Yes, LyngSat.com and FlySat.com do not list C3 anymore and on KingOfSat.net there is still an entry for Russian IPTV "Tricolor" (the same parameters as in 2017) but I cannot lock this signal with my TBS cards anymore.

MTSAT and MSG LRIT

Hello all,

Please anybody can tell me where does

MSGDM picks the images for the MTSAT and MSG LRIT.

it should be  on MSG-1 MSG-3 or MSG-4????

Thanks

This question is important because HVS-2 will be on the same transponder frequency as BAS + HVS-1.
If it turns out that there is nothing on C3 right now (if plot not current) HVS-2 on C3 will be the next culprit to lower
our SNR for BAS + HVS-1 on C4 as this was the case with the Russian IPTV "Tricolor" in 2017 ??

Ernst,

Yes, the cross-polarisation is an issue and a cause of reduced SNR. Not affected by signal strength either. Unfortunately I don't have easy access to my antenna, so I have to trust the "satellite TV" installers!

John is probing more than I have time for right now!

Re: EUMETCast Europe High Volume Service - Transponder migration in 2022

geojohnt@...
 

Ernst,

Your comments got me 'having a look around.'

Flysat no longer list a transmission on 11.263 GHz V.
Just EUMETCast on 11.263 GHz H.

However, my Inverto SatPal meter [which cannot decode VCS - so doesn't show SNR] shows 11.263 V is still active.

EUMETCast 11.263 H is showing a -30.2 dBm (90%) level and 11.263 V is showing a level of -35.3 dBm (81%).

Tricolor has expanded services considerably and now uses Eutelsat E 36 C [Express AMU1] which interestingly has both linear H and V and L and R (presumably) circular transmissions.

Regards,
John.

Re: Just a curiosity on SR1

Alan Curnow
 

The two RF inputs can be used in two ways.

(1) One RF receiver and demodulator input at a time with the method of selecting which one to use determined by the SR1 config. All 8 De-Capsulation filters in the SR1 are assigned to the RF receiver/demodulator input currently selected, enabling it to decode QPSK, 8PSK, 16APSK and 32APSK modulated signals from the satellite DVB-S2 data stream.

(2) Both RF receivers and demodulators in use at the same time. 4 De-Capsulation filters are assigned to each RF receiver/demodulator enabling them to decode QPSK and 8PSK modulated signals only.

The EUMETCast Basic Service uses 8PSK modulation but the High Volume Services use 16APSK modulation. So to receive the High Volume service only one RF input can be used at a time The Basic and HVS-1 are on the same transponder so the one RF input can receive and decode both services.

I bought my SR1 from Geo-Web.org at a reduced price, as they only had one receiver/demodulator fitted, so could only receive one RF input anyway, although the SR1 still had two RF sockets.

Cheers,
Alan Curnow

Yes, I found that link, but these days E 10 A's power output is low compared to many other similar  satellites:

Max Power contour level:

E 9B 51dBw.

A 10A 48dBw. Madagascar and south central Africa have 52 dBw.

E 13B, C and E have 53dBw.

E 16A - Europe A 49dBw, Europe B 50dBw, Europe C 52dBw.

So I quite expect E 10B to have a higher power output.

We shall see?

John.

John,

Same orbital location - great!  Different satellite, of course.  Oh, and not
yet launched:


https://www.satellitetoday.com/launch/2020/12/16/arianespace-to-launch-eutelsat-10b-in-2022/

As it's intended "to ensure service continuity for existing customers on
Eutelsat 10A" there's no reason to expect higher signal levels per se (but one
can hope!) but at least the transponders should not be nearing end of life.
"Continuity" is mentioned here:

  https://www.eutelsat.com/satellites/future-satellites.html?#eutelsat-10b

It's "All Electric" - no steam power!

David and All,

I have to correct myself regarding the end of Sentinel-3X OLCI ERF dissemination on HVS-2. The original deadline was set for 29. July 2021 and this has been extended in an e-Mail dating 26.01.2021. OPS wrote:

Dear User,

 

Following up on our email below, sent to you in September last year, we would like to inform you that we have decided to temporarily keep the Sentinel-3 OLCI Level-1 Full Resolution Near Real Time data on EUMETCast Satellite beyond 29 July 2021, to allow more time for users to transition to the available alternative access services.

 

A new date for the removal of these data from EUMETCast Satellite has not been defined yet, but it is likely to be during the last quarter of 2021.

<snip>

The Sentinel-3 data are currently planned to be made available from the EUMETSAT Data Store by the end of this year. In view of this, we would also be interested to have an idea of your readiness to set up API access to take full advantage of the NRT data that will be available from the Data Store.

<snip>


</cite>

So even if it's not 100% sure and we have no fixed date yet we must assume and be ready that Sentinel-3X OLCI EFR dissemination on HVS-2 ends by the end of 2021 as David recalled in the first place.

Regards,
Ernst
