Garmin Fenix 3

Richard’s track.

This watch uses the MediaTek MT3333.

GPS Babel

Firstly, stating this was entirely a consequence of running the data through GPSBabel, and serves as a warning that tools can do unexpected things to your data!

The end result was an apparent 25.36 knot spike @ 15:52:44 followed by a big 44 knot spike, following a crash. These spikes were NOT in the original FIT data.

The standard “max acceleration” filter excluded these from the GPSBabel results since “Sats”, “HDOP” or “SDOP” are not present.

Important note: This spike is not present in the Doppler speeds of the original FIT. It was only introduced by GPSBabel and is derived from positional data.
