Seems like everyone has forgotten about PARASOL... Which already did this over a decade ago! :-)

EUMETSAT@eumetsat.int

Since launching in Aug 2025, the 3MI instrument on board Metop-SGA1 has been revealing our atmosphere in a whole new way - measuring polarised light to track dust, smoke and aerosols with extraordinary detail. Our experts have put together a gallery of highlights. See for yourself: bit.ly/4pvbUSY

Radiotelescoop Dwingeloo@radiotelescoop.bsky.social

With the 25m Dwingeloo radio telescope, we just tracked #Tianwen-2 on X-band. It was at an offset of 1.1 degrees from asteroid Kamo'oalewa, which it is going to visit. We recorded IQ data, maybe others can decode this (@destevez.net, @aang23.satdump.org?). Data at data.camras.nl/satellites/r....

Following changes by @celestrak.bsky.social, it's possible some users of SatDump (I've already gotten reports, especially for anyone running more than a single SatDump instance) will experience issues updating TLEs. I have no easy way to fix this at the moment...

In much older versions (anything pre-2.0.0 potentially), this change will also trigger a bug causing a crash. Not much I can do either, never expected this kind of change.

METEOR-M 2-3 LRPT Projection of a few passes received by my station this morning, as Paris got some (nowadays quite rare) snow.

Happy new year everyone! 2026 should be the year of the return of LRIT / HRIT in Europe, as well as quite a few good SatDump additions & v2.0.0... But let's not spoil yet :-)

Paris Nord, last train at 22:30. Of course that excludes suburban traffic, but still far from what most of Europe offers in comparison... And yet, we're still canceling the Paris/Vienna/Berlin NightJets.

Come già anticipato nel post del NOAA-15 (RIP), adesso anche i satelliti USA futuri sono stati praticamente tutti annullati o lobotomizzati. Ricordo che attualmente nessun satellite USA copre l'orbita delle 08 (ex NOAA 15) e il successore JPSS-3 è previsto... nel 2032!!! bsky.app/profile/afre...

SCOOP: Trump administration slashes scope of next-generation US weather satellites, eliminating air quality and ocean observing sensors. (1/3)

NOAA-15 was decommissioned today at 15:26 UTC, with its AVHRR/3 Instrument still in better state than the last 2 remaining on MetOp-B & C. It wouldn't be so disappointing if this wasn't done for the wrong reasons... Makes you wonder what happened to NOAA.

Receiving @eumetsat.int's MetOp-SG A1's X-Band Direct Broadcast. It is 93.3M QPSK (Huge... Bigger DB yet). 1/2, RS 223 I=4 otherwise with both convolutional vectors swapped. All as expected... Now we just need to wait for EUMETSAT (or well, @esa.int for now) to turn stuff on! :-)

lego11@lego11.bsky.social

First reception of Metop-SG A1 at my station with @aang23.satdump.org and his Aaronia Spectran V6! Signal strength about the same as JPSS-2, but without nulls. About 10-11 dB on a 33° pass for my 1.2 meter Andrew dish. Signal is filler and telemetry only now, no instrument data yet.

Just got the news that the US Navy will *not* be stopping distribution of DMSP data in the end! As of now it's planned to keep SSMIS data distribution until September 2026.

Il nostro (mio e di @aang23.satdump.org ) lavoro di decodifica di SSMIS, strumento essenziale per rilevare e caratterizzare gli uragani, ma interrotto per motivi politici, ha attirato l'attenzione del Register che ha dedicato un articolo al nostro #SatDump! www.theregister.com/2025/07/21/s...

Demodulating MTG-I1 raw data @ 26Ghz received in Panska Ves. It is 188M OQPSK 1/2 and RS I=5. Unfortunately, it is encrapted. It's very disappointing considering it's supposed to be public life-saving data... S-Band is not encrypted.

This means weather centers could very well use #SatDump to still get the data they need for hurricane analysis, right now, in real time, with simple equipment. WSF-M also coming. @weatherprof.bsky.social @michaelrlowry.bsky.social @rarohde.bsky.social @altnoaa.bsky.social bsky.app/profile/aang...

It was recently announced that DMSP SSMIS data wouldn't be available - so with @lego11.bsky.social we decided to add support in SatDump :-) Still lacking more samples (IQ) to do projections, but we can already process SSMIS data. Calibration is likely possible as well.

The data is decoded from the RTD Direct-Broadcast data stream - available unencrypted over the poles and CONUS. That won't allow restoring full availability worldwide like before... But better than nothing?

Additionally, a lot of DMSP Documentation seems to have been wiped off the web. The DMSP Data Specification declassified a few years back for example cannot be found anymore... Too bad I already had it! :-)

2025-06-02 0326 UTC - Arctic Weather Satellite composites. I'm glad to see this sat is finally transmitting data again! Decoded nicely with #SatDump, after a minor patch to handle bad data caused by interference

Today, UVSQSat-NG was at 5M BPSK (instead of 2.5M the previous days). The same images are yesterday were sent in large, at a higher compression ratio. Here's 2 of the new ones.

A few more from today... Far too many to post them all.

I can confirm that our client, @uvsq.bsky.social , operator of UVSQSat-NG, downloads between 20 and 80 megabytes per pass with their Adrelys AGS-3 ground station... running Satdump ! ;) We are very proud to have been involved in this project, both on the ground and in space !

Aang23@aang23.satdump.org

Today's UVSQSat-NG Dump (@uvsqsat ). This time it dumped at 2.5M BPSK. Over 120 images received total. Here's a few.
