Start of run marker tab

Analysis software moves the start of run marker to the exact time that the vehicle accelerates away from a standing start. To detect a standing start, the software checks where the speed is low and the acceleration is high; Typical values used here are speed under 5kph and an acceleration over 0.1g. However you can change these values based on the application.

This value control by what distance the software is allowed to move the marker. Typically this should be approximately twice the maximum positional error on the GPS. The default value of 15m is plenty for typical data. However if the GPS data is bad due to tree coverage etc, then this limit should be increased.
