Inmarsat (L Band) detection

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

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

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

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
