Thought I would post on here rather than the chat group as easier to keep track!
After finally sorting out my V5 problems which I have been fighting for the best part of a year, I finally have a stable GPS position on V5 and things working much much better, which is great as its had me scratching my head for a long while!
One problem though, that is becoming increasingly annoying now that im into the silage season is the direction detection playing up…and I am wondering if the fact im using dual (or specifically, the fact the position antenna is offset to one side…) is exagerating the problem hugely, as many I speak to dont seem to have any issues…
So my setup is Dual GPS, using Tony’s basic code over UDP, which is super stable and fast I am finding… I use “Dual as IMU” as this prevents the typical Dual heading vs direction problem, which helps massively on a sidehill, or with any side draft in regard to keeping on the line… Because of this, direction detection is then a thing (which when using pure dual, never has been, and just works perfectly as you only use the true dual heading, which is obviosuly always instantly correct)…
What I am finding it probably 80% of the time, when turning on the headland, it will get mixed up, and be going the wrong direction when entering work again… This in itself is a bit annoying as you have to keep and eye and hit the tractor icon every time to correct it…but the REAL problem, is the fact that this then obviously hugely winds up the IMU fusion…so when you hit the tractor, it will take a fair distance for it to get “back in sync” again and drive correctly… This is obviosuly impossible when turning on the headland as you have no space to drive fowards enough for this to correct, which results in having to steering manualy for the first 20feet of every pass until its settled down again to hit autosteer…Which happens more often than it dosnt, so is getting rather annoying to say the least!
If you take long turns it generally works ok, its nearly always when you have to back up you get the problems, it seem to be if you back up at full lock, and then go fowards at full lock, this will almost always confuse it… And as I said before, I wonder if this is hugely influenced by the offset position antenna in a dual setup, meaning you are “driving around” the position antenna when at full lock, which makes it much harder for AOG to detect direction?
@BrianTee_Admin @BrianTee any thoughts on this? A workaround would be that hitting the tractor resets the imu fusion so that at least it would work once you hit that icon each time… But going fowards, how much work would it be to code in direction detection which is only calculated using the incoming heading from the DUAL, not the fix-fix… As this heading is always 100% correct, no delay, its just right, even if stationary… This would essentially fix all the issues I think?
