Satellite: I'd , signal demodulation.

#1

Unread post by CyborgSami »

Greetings,

A newbie to sdr's & satellite data feeds.

I'm picking up some infraSonic, ELF frequencies from a USO Unidentified Space Objects on my
newly acquired sdr dongle. See attachment.

What software is the best way to I'd the sat & demod the IQ signal data ?
I'm using the sdr-console. Rf-frequency analyzer app.

Cheer's

The picture did not make it. And modulo the USB dongle involved you may be seeing the dongle's imperfections. Idly, how is "infraSonic" used in this context? And how have you identified the source with any degree of precision?

Still a mystery. Screenshot of satillite frequencies captured with sdr.. Can clearly hear the signal tone, via the sdr. Need IQ file demodulated to reveal origin of the satillite. Satillite(s) is geo-stationary. Is the satillite friend or foe ? Who can solve this mystery ?
