Re: FY-3D

Ernst, Graham, Thanks for sending; I have now a couple of files.

Btw, these ARE readable using hdf5-software, but to extract the right info you need to know the buildup. That's also the case for MTG and GOES16/17. I don't think any hdf5-reader can read and interpret FY3D, MTG or GOES etc., without explicitely integrating the way the data is put into the hierarchical file, which is different for each mentioned satellite.

h5dump extracts hdf5-files and shows it in ASCII (don't try to print it ! ;-))

Regards,
Rob.

I'm on GNU/Linux. But David has a description of single cable operation here:

https://www.satsignal.eu/wxsat/dvb-s2/T1-T2.html

Maybe it's not exactly up to date but the Windows community can/will help you.

Hello

Thanks, What about BDADataEx do you need to have 2 instances or how you are doing tuning of 2 frequencies ?

Another Question:

About telicast. i have been wondering that currently i need to set interface address to 0.0.0.0 instead
of IP of SR1 or Satellite card. No you know any reason for that ?

Two instances is for HVS-1 + HVS-2 as described by David. But you can even take
all three services with a single cable and then must run 3 TelliCast client instances.

Esko

It works with a single cable because T1 and T2 are in the same band (high/low) and polarisation (H/V).
The TBS-6903 has two tuners and demodulators to pick out the exact frequencies. Two instances of the
tellicast client must run of course. This works fine under Windows and GNU/Linux.

I did not find any instruction from Eumetsat documentation

I have Quard LNB but at this moment only 2 cables.

In smaller Dish  i have also Dual  LNB wit 2 cables.

It all runs under Windows 10 64Bit since spring 2020. Douglas and Graham uses it and John just said he will try it next.
The FY3D (Micro Physics) image I posted recently in this thread was processed under Windows 10 64Bit PRO as well.

Sorry David,I did not have any files as I was not taking the satellite
data as I had no way of using the data in windows.
I will start taking data tomorrow for one day, so I have files available.

Regards
Ian.
========================

Ah, OK, I hadn't appreciated that you didn't have the data!

Good luck with the Python stuff. As Python works on Linux it should work on Windows with very minor tweaks.

Cheers,
David

maybe you asked for some more precise information like this (taken from one of my FY-3D PyTROLL/SatPy processing files):

Thanks for both pieces of information.

For me the problem started on 12th October and affects both SUOMI-NPP and NOAA 20 ascending and descending passes between 50N and 60N; at the moment I do not receive FY-3D
I emailed OPS and they informed me that they were not aware of any anomalies in the data. I have sent them my verbose logfiles and copies of the H5 segment files associated with today's descending SUOMI-NPP pass about 10E of the UK as delivered by Tellicast.
Interestingly the HF file  associated with the missing lines is always significantly smaller than its neighbours.
I have got Python working for GOES 16 under Windows 10 thanks to Ernst's guide. Hope to move on to polar orbiters soon.

For Suomi_NPP and Noaa_20 I can confirm your observations. The segments where we see the black gaps pretend
in their file names to be the standard length of app. 85 seconds. But their size is often only 50% of normal segments.

For FY-3D half of the pass over U.K. is simply missing. It's not disseminated. Documented for OPS on 3 orbits each.

Ernst

FY-3D segments are 1 minute long as you can see in the file names.
They come in pairs: 1000M image data and GEO reference files.

I am also hoping that they may check some things as they monitor the

Will keep in touch.

I had a look at all three sats Noaa_20 (VIIRS), Suomi_NPP (VIIRS), and FY-3D (MERSI) for the last 3 days.
It's quite obvious that the EARS processing/dissemination chain is broken somehow. I'll report that to OPS.

Thanks Ernst. As I said previously it is suspicious that it is (from memory) the 3 satellites that transmit in the 7800 MHz band.

Douglas.
