Mammotion YUKA 3000: Positioning failed / invalid

What this fault means

The mower cannot establish a valid high-precision position.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Move mower and reference equipment to locations with better sky view.
2. Confirm RTK/iNavi/network service is online and the app shows normal connectivity.
3. Check whether the reference station was physically moved or only reported as moved.
4. Restart only after firmware/update activity has completed.
5. If the issue began after an update, compare current firmware with Mammotion release notes before remapping.
