Robot Mower RTK/GPS Positioning Error

Quick answer: RTK/GPS errors usually involve sky visibility, base-station placement, signal obstruction, map drift, firmware/app state, or a moved dock/base.

Check first

  1. Check app status for mower GPS and base/RTK signal.
  2. Look upward from the mower/base location and note trees, rooflines, walls, or metal structures.
  3. Confirm whether the RTK/base or dock was moved after mapping.
  4. Power-cycle only according to manufacturer guidance.
  5. Do not remap until you document the current errors and site layout.

Likely causes

  • Blocked sky view at mower or base.
  • Base/RTK station moved after mapping.
  • Dock/base location too close to walls, trees, or metal structures.
  • Temporary satellite/firmware/app state.
  • Map drift after site changes.

Will this fix it?

These checks resolve many common cases. If the same error returns, the mower is unsafe, or the problem continues after the safe checks, it likely needs professional diagnosis.
