From about 16.55 Uk time some MetopA polar wind data (amv)
is incorrectly being sent on channel EPS-10 Basic service. MetopA polar
wind data is as it should be coming through EPS-10 on HVS-1, so I am not
sure if it is duplication, though a quick check suggests it is not.

Ian.
=================================

Thanks for spotting that, Ian. I suggest reporting to Ops if the issue continues.

Re: Dartcom Receiver

Graham Errington
 

I have opened the receiver up and it's not exactly the same but quite a few of the components used are the same.

Would you be able to scan what you have and send it to me, it might help.

All,

My SNR is way down at 16:00 GMT with only non rain bearing cloud.
I see that there are a lot of storms around Austria so presume the uplink is affected.

All,

Interesting, I see that we all suffered lost signal for short periods around 14:00 GMT from David's station readout graphs.

Yes there has been serious problems with all services since about 14.30 clock time UK with thousands of lost packets and no signal for long periods.
Looks to be better now. Likely the European thunderstorms as you say.

Dartcom Receiver

Graham Errington
 

I have the opportunity to buy a Dartcom Satellite receiver, 136-138 Mhz for weather satellites. There isn't anything on it to identify which model it might be. Knowing a bit about its provenance I know it is an older model but it is in very good condition.

ย 

The problem I have is I don't know how to connect it to my computer, there is a DIN socket on the back which is where all the connections will feed into, I've been told that there are two connections for a tape recorder and one for the computer.

ย 

Does anyone know what the wiring diagram is for the DIN plug and as I don't have a tape recorder anymore can it be connected to a digital recorder or is it really necessary and could I just dispense with this. I assume that the end of the connections are audio plugs to connect to the computer etc.

ย 

Also which is the recommended software for displaying the images/maps.

Graham

Greetings Douglas, I use the programme mainly for MSG data display and the other Geostationary
satellites, haven't made use of the "Projection" facility until now and the availability of NOAA20 data.
Your image looks good so now trying to manipulate/understand the "Projection" features to provide the image
quality available from NOAA20. Regards, John Morris

And as an example John here is a NOAA 20 image (one of my older ones) of
western Europe with a GVP projection in full colour.
Once you master projections it is very simple and remember you can save
projections (locations, zoom etc) in your POI file.

Douglas.

Hello John,

The raw VIIRS images (NPP and NOAA-20) are by nature meant to be projected to ,for example a vertical perspective projection due to the "pixel trim" fill values ( lines in blue). So it is not necessary to rotate the raw images.
You have to project the raw images to a LCC, GVP or a Stereographic projection.

Is it possible to rotate, by 180deg, a received NOAA 20 image when viewed
via Toolbox VIRS vertical tab and M-Band horizontal tab.
Advice welcomed.ย ย ย  John Morris.

Re: Waiting for Segments in AVHRR

Andy Clarke
 

Thanks again David,

Yesterday I successfully downloaded NOAA19, METOP A & B images of a very good quality using AVHRR Manager.

My next tasks will be to opsimsie the channel names in my HVS-1 and BAS ini files and then ensure I am only signed up for the data I need on the EOPortal as I only want GEOS16 & 17 and process in goesAbiManager, NOAA19 and Metop A-C using AVHRR and the images in MSG HRIT in MSG Data Manager.

Think I'll just enjoy the images for now though until I attempt that! ๐Ÿ˜Š

Subject: Re: [MSG-1] Waiting for Segments in AVHRR

Hi David,

Yes, really looking forward to grabbing some of the higher def images using AVHRR. I think I've finally worked out my latest mistake and why I can't see any data capture in AVHRR. When I requested the products on the EOPortal I naively selected GDS-Metop-A, GDS-Metop-B, GDS-Metop-C and GDS-NOAA - all AVHRR level 1. I think I probably should have selected RDS-EARS with EARS-AVHRR. Is this correct?

I probably need to optimise the channels I am saving at some point in the ini files along with the correctly requested products on the on EUMETSAT.

I basically just want GEOS16 & 17 and process in goesAbiManager, NOAA19 and Metop A-C using AVHRR and the images in MSG HRIT in MSG Data Manager. My primary focus though is looking at NOAA19.

73,

Andy

Kind Regards

Andy,

Briefly, if you want the AVHRR over an extended Europe you need the EARS AVHRR data, and the AVHRR Manager. That's NOAA-19 and Metop-A/B/C (C may not yet be released). RDS - regional data.

For world-wide 1 km data, GDS Metop-A/B/C, and three instances of my Metop Manager (one licence key). GDS NOAA-19 is ~4 km resolution.

Have to dash!

I just need to deal with the EUMETSAT-darmstadt files now.

What a clever programme to deal with three different data paths.

Sorry if you, or anyone else suggested this earlier - I've not been thinking straight recently.

Regards,
John.
====================================

Good to hear that you are making progress, John. Yes, it can be a lot to take in all at once.

I don't know whether making gradual updates and getting a resulting configuration far removed from current EUMETSAT standards, or simply starting from scratch each time is the better approach. I tend to end up with both methods - installing from scratch on a non-working test PC to get the new files and study the channel structure (perhaps adapting my software or perhaps not), then editing the existing installations with any important changes (TelliCast and the main .INI file, buffer) to check they continue to work.

Cheers,
David
