I've tried a couple of apps including GnssLogger but I dont seem to be able to get the Navigation file output, only the Observation file. I need both to have RTKLIB produce a solution. Any advice?

What device are you using?

Not sure if this is the root issue if you're using GnssLogger (I'm just getting up to speed on the new logging features there), but many devices don't support the navigation message API.

See column O in the GPSTest Database:

(if your smartphone doesn't support navigation message )U can down load the rinex file from igs.bkg or from cddis.nasa or u can use the gnss analysis application on windows to process the txt file from( gpstest or gnsslogger ) app in android to download the rinex files for your measurements

Using a Pixel 6, BCM4776, GLL ver. 129.20.23 524633. It looks like it should be supported there.

Well need the navigation file from multiple phones because we want to compute position remotely in real time and add RTK.

Any knowledge on how this can be done (or if its impossible) would be appreciated!

Have you tried using a SUPL client for this info instead?
