Slow speed rover operation

I have read other forum entries that warn of poor GPS velocity inputs when rover speeds are < 2m/s ~4.5mph. Will the Kalman filtering of this data adequately smooth this data? Additionally there has been mention of ESC deadband and hysteresis and the inability of maintaining consistent slow speed. Are there ESCs that have smaller deadbands than others?

My goal is to have my rover be capable of operating down to 0.67m/s ~ 1.5mph. Is this possible under autonomous mode?



Probably not.
You might have to employ RTK to get adequate positional knowledge at such a slow speed.
