Just try "Forest_NMEA". I used it in simulator fast mode (k750i and emu), effect is many times the same - no coords change for 50 m and next fast jump.
In "parowy" (means ravine) terrain is difficult for GPS (HDOP changing a lot), but you can see that I tried go out near 50m from cache and return to have better measurement (no coords change visible for shorter distance).
In "forest" log you can see low HDOP values, a lot of satellites and jumping coords (50m scale). I have no idea what's going on.

Indeed ? I converted NMEA "Parowy" with GPSBabel to GPX & next with GPS Mapedit to plt (this way you don't loose some log parameters ie time in plt) - pls find file attached. If you use this file in OziE you will see calculated distances in "Show track list" - most of them "0", few with near 50m jumps.

| Hmmm... hdop is constant, lots of sats... you say "slow smooth walk" - but most records have 0 speed, and now and then 50m jumps - didn't you turn on static navigation on your GPS?

Static navigation ? In Nokia LD-3W ?
All I can do myself with this module is turn on/off ... and reset.
I checked logs from previous TB versions and don't see such case.
Seems like not updated coords, but where ? In GPS module ?
Or no time to update coords when log was written ?
Strange ...

My LD-3W had static navigation ON by default - I had to turn it off using SirfDemo. And I try not to let the battery discharge completely, because the device resets to factory defaults then...

I don't have detailed docs of this module ...
From Nokia info - LD-3W have WAAS support and can be switched to night mode, but commands are unknown for me.
BTW, I didn't used any software to switch my module mode.
So what changed from TB earlier versions that nmea logs worked well ?

Nothing. Honestly. The code did not change since 0.9.3.
