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


Just a curiosity on SR1

Hello everyone,
I have just a curiosity.
As everyone knows Ayecka SR1 has two RF connectors while it is used just one. Please what is the other one for?
Thanks

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?

Regards,
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:

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

Simply using the filename will define the mapping and sub-satellite point. The program accepts GSHHG (or GSHHS) data in the options for overlay. Sample blank attached.

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:

<cite>
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

 


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

George Sz
 

For those still wishing for a single cable installation (or can't run another cable), there is actually a solution: Unicable. As an example, here's this product: Inverto Unicable II LNB. I just wonder if there is an opensource solution to program this, because buying that SatPal programmer would be a waste for a single use installation. Relying on "on the fly" DiSEqC commands would still work but on a power cut those would be reset. All in all, not super reliable, I think. So best would be to permanently program the Eumetcast TPs for 3 selected user bands.

Regards,
George

Yes the tentative launch date for 10B at the moment is December 2022, so we are probably about 2 years away yet from the switch over.

David,
thanks for the heads up. I was about to ask OPS concerning these migrations as I was not
sure whether future HVS-3 would be on the same downlink sat. What EUMETSAT plans now is
mainly good news as we can go in the near future with one antenna and downlink sat only!
Nevertheless a couple of TC users might be affected by the first step C10 --> C3 in 2022.
If you use CrazyCat's single cable solution with a TBS-6983/03/08 or TBS-6903X to receive
BASIC + HVS-1 + HVS-2 you will need at least a *TWIN* LNB and two cables to your antenna.
The same is true for users with 2 USB boxes and/or DVB routers with single cable plus splitter.

P.S.
With 4 cables + *QUAD* LNB + suitable TBS-card(s) you are ready including HVS-3 in July 2023.
Yes, Ernst, I've been recommending QUAD for some time!

I'm unsure what is going to be on the different services. I recall that Sentinel data is being dropped from HVS-2 at the end of the year. Did I remember that correctly? So what will it used for - MTG-1 test data?

With the link margin being so low on that service at present I don't use any of the data - there are plenty of Internet sources already - but I do have one TelliCast instance monitoring it. I'll have to consider what to do nearer the time.

The good news is that the present C3 signal (11262.5 MHz vertical) - red in the attached plot - appears stronger than the present C4 signal (current BAS etc.), and much stronger than the present 11387.5 MHz horizontal. So maybe HVS-2 will enjoy a brief reprise? Of course, that's one measurement at one location. Can you confirm that? It may also be that C3 also needs to be backed off more for acceptable 16APSK performance.

David

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dear EUMETCast-Europe User,

EUMETSAT operates EUMETCast Europe in Ku-band via EUTELSAT 10A (E10A). The E10A
satellite reaches its end of life in 2023 and will be replaced by E10B.

The second transponder used for EUMETCast Europe High Volume Service, C10,
cannot be used at the same downlink frequency on E10B, so migration to a
different transponder, C3, is required. This migration is foreseen in 2022 on
E10A, and the replacement of E10A by E10B will then be transparent to users.
The migration will include a parallel downlink period on the old and new
transponders, to allow sufficient time for users to adapt their reception
equipment.

the migration, please see our web news:
