GSD4t GPS support
- Galaxy S2 (I9100)
- Galaxy Nexus (I9250)
There was some attempt long time ago at GSD4t, however nowadays there seem to be a free software implementation of it already in gpsd (git://git.sv.gnu.org/gpsd.git).
Porting GPSD to android might be doable.

big chunks of the GSD4t protocol have been decoded at https://github.com/mnalis/gsd4t_parser
While something looking like GPS 50bps data have been extracted, it is still not enough to get a GPS fix.
Unfortunately, I've been unable to hack on it for some time, which probably won't improve as I'm not using that phone anymore.
So I'm documenting this in case somebody wants to take over and try to decode remaining bits)

I haven't tried it yet, but it looks like someone has a tutorial here on how to install the Guix package manager on Replicant: https://www.gnu.org/software/guix/blog/2018/guix-on-android/
I don't see gpsd packaged https://www.gnu.org/software/guix/packages/G/page/9/
Perhaps someone could write the needed recipe for it and add it as a package to Guix so that we could install it on Replicant if gpsbabel won't work to solve the ticket.
