Re: Dish elevation lever.

geojohnt@...
 

Hello Ernst,

Sorry for the delay in responding.
Thanks for the post.

Ah, the dreaded Triax dish mount.
Totally impossible to secure the dish to the post without some dish movement remaining owing to the crazy design.
OK for satellite TV perhaps but not for the alignment accuracy we require for EUMETCast. 

Triax told me they had not had any complaints about difficulty in aligning the dish accurately from users and were not going to change the design.
The 'semi circular' dish clamp - clamping onto a 'rounded bracket' back plate allows for azimuth movement and it is impossible to clamp elevation and azimuth separately whilst aligning the dish.

I seem to remember Arne had made a device but I'm not sure I've seen this one before.

Simple and looks very effective. 

Regards,
John.

Hello John

I designed such a thing for the Triax TD100 that has a very poor elevation control.
Arne van Belle redesigned it for an easy homebrew construction. Maybe that helps.

Re: A68 gif animation December 01-08

Ernst Lobsiger
 

Hi Thorsten,

a very nice image. The ice even sometimes looks light blue! You can also see the smaller pieces floating ahead. A68 is turning CCW the last days also seen on my pictures. This animation tops about everything before. The only improvement I can think of is using a higher resolution for the coastline. These exist in the GSHHG Data Base. A68 gives us a nice contest and makes a lot of fun (might be less fun for the Penguins on South Georgia). We will probably see more results: Graham Woolf and Christian Peters might soon be ready with my Pytroll/Satpy Sentinel-3 scripts for the final showdown ;-).

Best regards
Ernst

O.K.

Here is the Sentinel-3 Update for Windows 10. There is a README with 10 check points you have to follow.
You should see A68 crashing soon. For european areas I noticed that EFR files rarely go north of Scotland.
It seems to me that there is still enough light to disseminate one more northern 2 minutes segment. OPS ??

Good luck

Re: Missing segments

Giftmacher
 

Take a look at this, I have basically same problem, but I can't see that E drive, where is the data from Tellicast stored, would be too busy. (Kioxia 512 GB SSD for system and Patriot Burst 1TB SSD for data).


Re: Missing segments

Ernst Lobsiger
 

Daniele,

has your LapTop ever worked fine as an EUMETCast6 receiver a couple of days non stop?
If not and if this is a rather recent LapTop chances are that you have an SMR 2.5'' HDD inside.

If this is the case, check this thread, try to find the exact make of HDD, check HDD load in Windows

https://groups.io/g/MSG-1/message/29669

In short, an SMR HDD cannot be used as database for a TelliCast client. It's just crap.

Regards,
Ernst


Re: Pytroll/SatPy for EUMETCast

Ernst Lobsiger
 

Dear All,

David confirmed there is still plenty of space on MSG-1. That let's me post my best images from A68 so far.
OLCI full 300m SSP resolution shows that there are a lot of small icebergs ahead (probably fallen off A68).
I post one image from each Sentinel-3A and Sentinel-3B. So you can make sure that these are not artefacts.

Cheers,
Ernst


Re: Missing segments

Ernst Lobsiger
 

Daniele,

I can't say that I was looking for something like that. It shows a catastrophic (Basic) TC client.
EUMETCast HVS-1 and HVS-2 clients have their separate logs that must be treated as well.
If you are running 24/7 (I guess not on LapTop?) you would setup 3 copies of TClogSummary
and edit the header to indicate the service in the output. Your version 0.91 is deprecated.

I have thrown my Windows 7 PC away and only found the attached version 0.95 on a CD.
You should at least use V. 0.95 with newer clients (I hope it works, rename it to *.cmd first).

I have only EUMETCast receivers under GNU/Linux here. In any case David Taylor is using
TClogSummary daily on a bunch of Windows EUMETCast receivers and can certainly help.

Regards,
Ernst

Daniele,

it seems you only checked the most recent log (see date and time). This does not shed light on why you missed files last week.
"Transmission interrupted" (it's for priority reasons) is harmless. This transmission will be resumed and files will come in later.
"Transmission ended" on the other hand means files will be lost. A "missed (part of) file/s" message follows almost immediately.

As I said: Open the log files in an editor and search for 'ERR' and 'missed'. You might have more than one log per client:
Check for the date time fields in the lines. These should be from last week when you had your TelliCast reception problems.

I don't know of any limit on size, but I do have my personal account set to download NO attachments, so all the images stay on the server.

Isn't all Sentinel data available through Copernicus Open Access Hub (formerly SciHub) in any case? This should include Sentinel 1 (SAR) European coverage.

https://scihub.copernicus.eu/

They have an App you can run on Android or iOS (although not the most recent iPad, sigh), and a download manager for MacOS and Windows:

https://play.google.com/store/apps/details?id=esa.sentinel&hl=en_GB&gl=US

https://apps.apple.com/us/app/copernicus-sentinel/id1036738151

Using the app on a small phone screen is awkward, to say the least!

Folks,

The JPEG size is 12,084 kB, so no problem. The size depends on the compression level, of course, so perhaps you have a "Save As" option where you can play with the compression level to keep the detail while reducing the file size.

There's some information on storage limits here:

https://groups.io/g/GroupManagersForum/wiki/7137

MSG-1 is currently using 47% of its allocated 1 GB storage, mainly in attachments, so if we need more we'll need to upgrade us from Basic to Premium. It could cost $220/year (from the last figure I heard).

So if you like the images be sure to take your own copy (noting who is the originator to give them credit should the image be published).

Cheers,
David

SNR 13dB sounds rather good. You may have missed the segments for other reasons like high disk activity or EKU problems.
Check your client logs in the clients web interface first. Then take the log files in an editor and search for 'ERR' or 'missed' .
