GPS position should prefer SatellitePositioningMethods else it is usually broken with Geclue #56

GPS position should prefer SatellitePositioningMethods

When Geoclue 2 and gnss-share are used on Librem 5 phone and probably even on the other systems then incorrect position is obtained from QGeoPositionInfoSourceGeoclue2 plugin because GPXsee it does not require GCLUE_ACCURACY_LEVEL_EXACT. So only rough location pointing to the city center is provided. May it be it works on systems and plugins as serialnmea which do not provide alternatives and full PositioningMethods selection and enumeration. But for general case, GPXSee setup of QGeoPositionInfoSource is deficient.

The fix is available in my zoom-by-pinch branch. See https://github.com/ppisa/GPXSee/commit/f7e0282fda93be5ff64147f4a5a571df1b3a208b

When the QGeoPositionInfoSource is correctly configured by setPreferredPositioningMethods for QGeoPositionInfoSource::SatellitePositioningMethods the location is tracked.

Be sure to check that the correct source is setup in /etc/geoclue/geoclue.conf.

Se section

[network-nmea]
enable=true
nmea-socket=/var/run/gnss-share.sock

Ensure that socket name matches unix socket path created by gnss-share and that [agent] section whitelist includes gpxsee and gpxsee section is provided

[gpxsee]
allowed=true
system=false
users=

Then GPXSee has chance to be used offline map GPS application. I use Garmin maps.
