internal dual GPS with RTKLIB function?

[Magke]

hi, are there plans to make the internal dual GPS of xiaomi 8 usable?

This would be awesome, even if you had to install another version of Android instead of the factory version. Neil.

no work with internal gps of xiaomi 8 at moment....

Is there a technical limitation or is it "just" a matter of finding the time to add the code ?

It's possible to save the raw GNSS measurements on an android phone (GNSSLogger, Geo++, etc) and then use those files in RTKLIB like normal, so I think it's "just" a matter of finding time to add the code.

How much time and how much code, on the other hand...

Edit: And it seems that someone is doing work on just that: https://github.com/farbro/RtkGps/tree/InternalReceiverSupport (although last update was 2 years ago)

Thanks, I couldn't find any reference over there to using the internal GPS module of the Mi 8 though ?
That Alpha 26 works pretty well with an old uBlox 4 Bluetooth receiver I have, although it can't get an RTK Fix (unlike the Windows version of RTKLib).
But yes, there are tools to convert the raw Android GNSS measurements to Rinex so hopefully they can be integrated in an app one day !

I didn't look directly at the code in that repo, only the commit messages on the InternalReceiverSupport branch:

I couldn't get the latest commit to that branch to compile(/sync?), but Android apps are far outside my usual work.
