gpstest isn't really a "process raw data" client and I think should not cross into that. Can you point to android APIs where there is anything about OSNMA? To me, this request doesn't fit the scope of gpstest and should be closed, but maybe I'm missing something.

No API link has been provided, so I suggest closing.

I'm open to adding this as part of spoofing detection. Data will come from the navigation message - https://developer.android.com/reference/android/location/GnssNavigationMessage

this is very interesting, especially for folks who suffer to live / be in areas where GNSS gets jammed / Spoofed...
