This looks OK to me. The reason looks like to be you walking pretty slowly and/or not far enough during those 10 second intervals...
a trackpoint in time interval mode, the conditions at https://github.com/nohal/OpenCPN/blo...util.cpp#L2483
have to be met
Translated to English
The mode has to be turned on AND at least the time set in the configuration must have passed since the last recording (this one should be OK, unless your GPS is sending the data out less than once a second - you can see if it's the case in the NMEA
stream window) AND the position has to be at least m_minTrackpoint_delta nautical miles from the last recorded trackpoint. This value comes from the empiric experience and is set in the code to 0.001 nautical mile (approx. 1.9 meters) and it's there to filter out the always present changes in the position reported by the GPS even if it does not move a single
This common error in GPS reported positions is also a response to "But I walked more than two meters in those 10 seconds and still nothing was recorded"
As track recording is intended to actually record
a way traveled by a moving
target, this logic poses no problem in the real usage scenarios IMHO.
