Hi Ian

Thats not strictly true !!

I am running Windows 10 and am using python with some scripts very kindly supplied by Ernst - Douglas has done the same

It was a bit of a learning curve but well worth it

Graham


Re: FY-3D

Ian Deans
 

Just checked my FY-3D files for today and the pass to the west of the uk has 1 minute files starting 13.49 up to 14.02 which starts in Africa and just includes the very south of the UK. The next file is 15.32 on the next pass. So most of the UK and north missing completely.
If anyone else can check their files that would be helpful.
Files are typically :-
FY3D_20201022_140200_140300_15223_MERSI_1000M_L1B.HDF
There are also similar location files for each time sector.
Regards,
Douglas.
===================================================================

Spare a thought for us Windows guys, we do not have any program that can even visualise FY3D ---- our gap is total !!!!!

Regards
Ian.

Hi Graham,

I see the same thing ...and this is going on for at least a few days ....

Kind regards,

Hi Douglas

I still think there is a problem

I had a near perfect NOAA20 night pass apart from one segment again over the UK (see screenshot)

Did you see the same thing ?

It cant be coincidence that this is happening every day

Hi Ernst

Thanks - I might take you up on that

I know nothing about Linux so it will be a steep learning curve

Ill start looking for some cheap PC's

I can confirm to have received the files with gaps you are talking about. I have not checked their location though ...
Ernst
===============================================================

Thanks Ernst so that is 3 of us seeing missing files. Think Eumetsat need to re-check this.
The previous pass also had problems.

When time allows I will try and document a day (including verbose log file) and present the data to Eumetsat.
Will concentrate on FY-3D for the moment but NOAA 20 and NPP have some issues as well. Don't they all transmit in the 7800 MHz band.

Douglas.

If you dare to give GNU/Linux a try (I could give you a hand) you will get away with these specs:

Intel Core2 Duo 3.16GHz or later, 8GB RAM, 120GB SSD (System), 1-2 TB HDD (CMR!) DATA.
You must have room for two additional network cards. Except for the two disks you should find
such a PC for free. You *must* know your dayly data volume, it's easily around 400GB and it's
hard to process that all. You can use SAMBA to export the data to a Windows processing PC.

I still use my almost 12 years old Fujitsu/Siemens Esprimo Core2 Duo and recently got a bunch
of 7 years old DELL Optiplex 7010 I5 SFF all for free. NICs Intel1000 app. 10 Euros from e-Bay.

Cheers
Ernst

P.S:
Once again: Beware of SMR disks. This crap cannot be used for EUMETCast Data! It *must* be CMR.
There is a thread about that on this list. HDD manufacturers now declare SMR/CMR in the datasheets.

Dear Graham Woolf,

We do not see any problem with the data and we are also not aware of problems with SNPP VIIRS, NOAA20 or FY3D.

The files you mentioned are this type:

SVMC_npp_d20201021_t0012197_e0013439_b46544_c20201021002140000768_eum_ops.h5

Could you please send us the tellicast log files (recv_bas.log and recv_hvs-1.log) in order to check all the files  were disseminated via EUMETCast?

We hope you have the tellicast log files in verbose mode.

Unfortunately I dont run in verbose mode

Graham
========================================================================
Graham that report from Eumetsat seems to be quite incorrect.
FY3D data over the UK has been missing for months and recently NPP and NOAA 20 are having similar issues.
I have checked and the files for the time frames concerned are not there.
I will change my log to Verbose and see what it shows.
I am in the middle of decorating at the moment and with 2 arthritic knees and a hernia it is taking rather longer than usual !!
Once I get all the evidence for one day I will contact OPS.

======================================================

Graham,

If using USB there's an element of luck judging by my recent experience, and I find a network connection to be more reliable. I have two PCs which are essentially capture-only, both not this year's model!

BAS:
PC Harstad, https://www.satsignal.eu/mrtg/performance_harstad.php
8 GB memory, i5-4460, no special graphics card, 500 GB HD, 4 GB RAMdisk
2nd network interface for an SR1.
If I were buying today, I might get 16 GB RAM, 128 GB SSD (system) 0.5-2 TB HD as data buffer
Received data is on RAMdisk, and a Robocopy job moves it to the HD every minute
Received data offered as a network share, so the MSG Data Manager etc points to \\Harstad\received - used by PC Penguin.

HVS-1 & HVS-2
PC Lund, https://www.satsignal.eu/mrtg/performance_lund.php
16 GB memory, i5-6400, no special graphics card, 128 GB SSD, 4 TB HD as buffer, 10 GB RAMdisk
TBS6903 PCIe card with "single-cable" operation.
For various reasons:
HVS-2 received on RAMdisk and deleted immediately.
HVS-1 received on RAMdisk and Robocopy moved to HD, and unwanted deleted immediately.
Wanted HVS-1 channels (Metop-A, GOES-16/17) made available as network shares for another PC to receive (PC Penguin), shared over the house 1 Gbps LAN.

SVMC_ files are 600+ MB monsters which, in my view, deserve no place on the BAS!

One advantage of the two PC system is that you can, if you wish, disable updates on the RX PC so that data is continually collected, and the processing PCs can be kept up-to-date with Windows Update without data loss.

I hope all the above is correct.

E&OE

Cheers,
David

=========================================================================

Graham is your intention to receive and save the data only on your Eumetcast computer and use the other computer (across a network ?) to process the datas. For future larger data sets I am thinking along those lines as well although I already have a very good specification back up computer (8 years old) I could use.
Initial quick tests seem to indicate that the occassional losses do not stop.

Regards,
Douglas.


Re: PC Spec

Graham Woolf
 

For example

There is no point buying an i7 if an i3/i5 would do
Also there is no point buying 32GB of RAM when 16 would do
Do I need three HDD's for the three services or would one big one do

Should I use linux or Windows?

Its these sort of question I would like some advice on as it will only be receiving -it wont have any internet connection

Regards

Graham

Hi

Thanks for that - I have used them in the past

Re: Silicon Labs CP210x driver.

Hi John,
My impression was that you needed to connect the SR1 to the desired com port (no clashes - I also run a weather station that uses the same sw) and then the port would show up in the device manager. 

Cheers,

James

Hello All,

I'm going round in circles!

Does the SR1 have to be disconnected before you install this software?
The Ayecka SR1 DVB Receiver EUMETCast Guide appears to suggest this.

I run 24/7 and don't want to interrupt the service but Ops suggest that my TC missing packets and SR1 Controller anomalies might be due to using the data link for monitoring.
I have bags of SNR and my computer is not 'stressed' so I shouldn't see missed packets(?).

I have cleared out all my old copies of CP210x - which were 'all over the place,' and just downloaded a fresh copy.
I unzipped the zip file and ran the installer and the Wizard told me that the software/driver was ready to use.
However, it refuses to show in Device Manager Ports (COM & LPT) list.

I'm losing the will to live.

John Tellick.
