I tested GPS logging on my way back home from the office.
First issue I noticed: after saving my track with all options selected (inluding “GPS accuray” and “Speed”), I wasn’t able to import it into BaseCamp:
This is how GPSLogger’s GPX files are written (no problems importing into BaseCamp):
This is how Kurviger’s GPX files are written (no import into BaseCamp):
After deleting all the yellow marked sections (speed info) I was able to import it into BaseCamp.
Maybe the reason is a difference between GPX 1.0 and GPX 1.1?
Apart from that the track seems pretty good using the default options in the GPS logging settings. For a distance of aprox. 68km the track consisted of aprox. 700 trackpoints. Accuracy was pretty good (apart from a short “breakout” because of regaining GPS signal after leaving a tunnel).
