Decided I would start a thread on here rather than cluttering telegram,
As many will know, I have been having some real teething issues getting my dual antenna system up and running… I have been having all kinds of issues with erratic position jumping around, erratic heading issues, causing the autosteer to go quite crazy / very un consistent. In the process of tuning / tweaking / playing, I have many times, got the system to a point where I thought it was perfect…but then to find a few minutes later its less than ideal, if not un-useable again.
In the process of diagnosis, I have been swapping back to my old sf3000 receiver (serial connected), and also a single F9P with rover config on it…including with, and without RTK correction, but what I am finding, is it makes no difference which setup I use, weather it be Dual (ESP), single F9P, or SF3000, I am getting the same erratic behaviour, that sometimes will work perfectly, and others (most of the time) be completely useless…
Today i plugged i my Deere greenstar monitor, as it happens just to look at the serial settings, but made a discovery, it seems that out of the blue, the SF3000 just totally looses GPS signal… either to 0, or very low (15-35%)… occasionally it will climb back up, but then just beep at me / drop right off again… This prompted me to wonder, do I have a bigger problem going on here?
So out of interest at this point, I disconnected everything new, and went back to my old system, that I have been using for 5+ years, which is the SF3000, serial into my tablet, with FarmerGPS…and am finding that the signal can be erratic in there also…
So I am thinking something is causing huge interference with my GPS, which is quite likely whats causing all of my troubles all this time! But I cant figure out what it could be… have ruled out alternator as still seems to be the same with engine off vs engine on…and have unplugged everything that I can think of that is aftermarket electrically on the tractor…
Does anyone have any ideas what could be causing this chronic interference?
The behaviour I get is just very jumpy position / heading, when on the line, it will constantly jump about 20-30 cm left / right, playing havoc with the system…
