Settings: minimum GPS accuracy to start recording track

[Cigaes]

Hi.

Please consider adding in the settings an option to wait for the GPS the have reached a good enough accuracy before starting the recording. The option can be just a number: 0 for disabled, or 10 to wait until the accuracy is below 10 meters.

Rationale: the recorded points at the beginning when there are only a few satellites disrupt the computation of the distance, especially vertical.

Work-around: I have started to run GPS Test before OSMTracker and wait before starting the recording.

Thanks in advance.
