Mammotion LUBA "Poor Positioning" or Lost RTK Signal? How to Fix It
What Mammotion's Fix, Float and Single statuses mean, and how to tell whether the problem is the mower's position, the RTK reference station or its connection, using Mammotion's own support guidance.
Quick fix
Open the positioning (POS) screen in the app. If the reference station sees fewer than about 20 satellites or shows a weak signal, move it to open sky. If the mower does, move the station or boundary away from trees and walls. If the station connection shows "None", check its power, LED and radio antenna.
"Poor positioning" means your LUBA doesn't know precisely enough where it is to mow on its own. On models that use satellite RTK with a reference station (such as the earlier LUBA models), Mammotion's support pages explain how to find the cause. These steps follow that guidance.
1. Read the positioning status
Open the positioning (POS) information in the Mammotion app. Mammotion defines the statuses like this:
| Status | Accuracy | Can mow automatically? |
|---|---|---|
| Fix | Within 10 cm (as little as 2 cm in open sky) | Yes |
| Float | About 50–200 cm | No |
| Single | Meter-level | No |
| None | No position | No |
The screen also shows how many satellites the mower and the reference station can see, how many they see in common ("co-viewing"), the signal quality of each, and the connection between them. Mammotion says more than 20 co-viewing satellites on both L1 and L2 frequencies is good for stable positioning.
2. If the reference station is the problem
- Fewer than about 20 satellites at the station, or weak/bad signal quality: the station's view of the sky is blocked. Move it to an open-sky spot away from trees, walls and fences.
- Station shows 0 satellites and the connection shows "None" or "Weak": no data is reaching the mower. Check the station's power cable and adapter, check that its LED is solid green, look for water inside it, and make sure its radio antenna is fitted.
- You replaced the station: pair the new one with the LUBA in the app.
3. If the mower's position is the problem
- Mower sees fewer than about 25 satellites or has weak signal: something above or behind it blocks the sky, often trees or walls, or metal near the charging station. If it happens at the station, move the station to a more open spot.
- It happens at the edge or a corner of the lawn: use "modify boundary" in the app to keep the boundary away from the obstruction, as Mammotion recommends.
- Satellites show 0: check the mower isn't indoors or covered by metal. If it still sees nothing, contact Mammotion support.
4. If the connection is weak
A weak connection between the mower and the station can mean the mower is too far away or that thick walls or buildings stand between them. Move the station closer to the mowing area or into line of sight.
When to contact Mammotion
If none of this helps, Mammotion asks for photos of where the station and mower are and an uploaded log. Newer models with LiDAR (LUBA 3 AWD, LUBA mini 2 AWD) are less dependent on satellites under trees; see RTK vs LiDAR for why.
Still not working?
If the fixes above don’t help and your mower is out of warranty, a repair can cost more than a replacement. Compare current models before you pay for parts.
