We have a tractor that we are using for grain bagging. It is comically slow when it is moving but it would be extremely nice if we could use autosteer during this operation. Is there a minimum speed required? I know in commercial autosteer settings seems like they need 1.1 or 2 mph for autosteer to work. I would think with going to slow it wouldn’t really update the location often enough/too much, making it steer back and forth horribly. This is moving at maybe .2 mph.

Not sure but at a guess you would need full RTK, and maybe duel antenna so the system can read that slow speed.
If it works but is making the wheel move loads maybe turn down some settings, dull down the wild steering motions.
The duel antenna plus duel RTK from them is a guess because feildbee do a low speed kit, that needs 2 receivers to do so. The accuracy is needed to see the slow movement.
yes just set your minimum speed in the steer settings expanding tab
mine is set at 0 for hedgecutting so it doesnt disengage when i stop
Probbaly setting minimum gps step from 10 to 5cm will also help with very slow speeds
Do you have dual gps and rtk? I was hoping to just use a single waas antenna to keep it cheap.
WAAS will drift ~8" every ~20 minutes. You absolutely need RTK.
You won’t have a useable fix to fix speed and you can’t rely on the IMU alone for heading. You absolutely need dual.
I am aware of how far waas will drift, but that would still be way straighter than hand steering it occasionally. The dual antenna is information I didn’t know, thank you

Might be str8(it wont) - since you are going with slow speed it will take a lot of time to complete one row, in that time it will shift and your next row will start overlapping with previouis or leaving big gaps. Also you lose repeatability if you need for spraying, cultivating, anything you cant repeat the same path again without rtk. It can be up to 1.5 meters away from where you made first run.
single antenna and wheel angle sensor with imu on rtk
