I just started testing my setup without steering so with just PCB, IMU and antenna connected. It worked fine at first but when I moved antenna to front of the cab to its final position, measured and entered all tractor settings/measurements to AG it started showing tractor moving sideways on the display. IMU roll seems to be working nicely and I have RTK fix.
What is the reason for this? Before I had only pre set tractor measurements and antenna was on top of the rear axle, then it was working fine.
My setup is Kaupoimod 4.1 pcb with CMPS14 and simplertk2b starter kit as antenna.
Also another thing I noticed when driving that my speed isn’t stable. When driving steady 30km/h on the road, AG speed jumps between 27kmh and 45 kmh. Is this normal? At 10kmh speed was jumping between 9-14kmh.
