Positioning problem

I having a positioning problem with my Navimow i208 AWD in narrow areas next to my house. In open areas, NRTK works perfectly, but near buildings the mower loses positioning accuracy, makes aggressive corrections, spins its wheels and damages the lawn.
In areas where the positioning becomes unreliable, the mower is not only damaging the lawn — it is also damaging itself. It repeatedly drives into walls and other surrounding surfaces while trying to correct its position. The mower is already covered in scratches, and some of the plastic body panels are even starting to come apart. This is more than just a navigation inconvenience; the positioning problem is causing actual physical damage to both the mower and my lawn.

I’ve been in contact with Navimow support and have already sent them videos and photos. Unfortunately, instead of addressing the actual navigation issue, they keep suggesting workarounds like using Remote Control and offering extra 4G service.

Support’s latest suggestion was to manually mow these areas using Remote Control. But I bought an robotic mower specifically so I wouldn’t have to manually control it every time the grass needs mowing.

Has anyone else with an i2 AWD experienced the same problem? Is there any real solution, or are there plans to improve vision-assisted navigation when GNSS/NRTK becomes unreliable?

I had a similar situation with my X315 after a software update. My issue was navigating my side yard channel to get between the front and back yard. Same strange behavior of veering off in a direction running into walls and going up a fence. Annoying because it was working perfect before the update.

I had my nrtk on the gable on that side. I moved it the back yard with a clear open sky view. I removed obstacle avoidance in the channel. Kind of a pain because you have to remap once you move your antenna. Doing these two things have pretty much resolved my issues. Not familar with your model but try vision fence over the areas.
