What about adding support for 0,5m accuracy for positioning on Jolla using the free Finnish Geodetic Institute DGNSS service? :P http://euref-fin.fgi.fi/fgi/en/positioning-service/dgnss-service

Radio talk about this subject in Finnish. They mention that they have received a couple of phones for testing but generally they cannot access the required data on smartphones to utilize the correction data. Possible with Jolla? http://areena.yle.fi/radio/2378158?start=14m17s

Collector for ArcGIS works great on Jolla so this would make it an awesome surveying device. https://play.google.com/store/apps/details?id=com.esri.arcgis.collector&hl=en

Interesting technology. Of course a lot depends on how that data is supposed to be recieved, Guess somebody should ping them and have them contact Jolla.

I’m very hopeful of Galileo. I hope all goes well with that project! :D

The GPS position calculation is done in the firmware, which is closed source by Qualcomm. So all DGNSS information that applies to the satellites itself won't be of any use. I couldn't find the actual contents of the RTCM messages (maybe someone else can?), but unless they contain some general adjustment of the GPS position after calculation, you probably won't be able to use it on Jolla.

GNSS receiver and antenna quality should be also taken into account. Differential corrections from a nearby DGNSS station are not a magic bullet for getting high accuracy and high precision location data, if the receiver+antenna combination isn't up to the task.
