Inmarsat (L Band) detection

#1

Looking to detect Inmarsat transmissions (1575.42 MHz). Has anyone had any experience with this?

#2

Just to detect, or are you wanting to perform some DOA analysis on them?

#3

The initial priority is to detect, but ideally DOA. Thanks

#4

Just like any RTL-SDR you could use an LNA + patch antenna. For DOA the spacing requirements might be too small for a typical patch sizing, so you’d need to design and build your own patch array.

Thanks Carl - appreciate the advice
