Using RTK/GPS technology, the Luba series from Mammotion can be a great alternative to a wired robotic mower. Still, some limitations and installation rules must be considered before purchasing. Let’s answer the question that brought you here: Will Luba work on my property?
What can cause potential issues?
Both Luba and RTK reference stations require open sky to receive GPS signals, and you need at least 20
satellites co-viewed by both for accurate positioning.
The reference station uses a radio signal to communicate with Luba to correct the signal down to 5cm accuracy.
The following might cause issues with Luba being able to work correctly:
1. Buildings that are close together, where Luba might not be able to receive satellite reception
2. Metal buildings or obstacles which might block the radio signal
3. Trees: Many or trees with dense canopy, which might block satellite reception
4. Charging station positioned close to house/building, which might block satellite reception
What environment does Luba need to work correctly?
Luba installation has 3 key components:
1. Luba:
Luba needs open sky to receive GPS signal. It does not have to have direct line of sight with the reference station if they both see the same satellites.
Note: Metal buildings or other obstacles might block radio signal
2. The RTK reference Station:
The reference station requires 120 of open sky to receive GPS signal and uses a radio signal to communicate with Luba to correct signal down to 5cm accuracy.
3. The Charging Station:
The charging station needs to be positioned in an open sky environment, as Luba needs to see satellites when docked.
Important: Both Luba and the RTK reference station need to co-view at least 20 satellites to maintain a good
positioning fix
How can I find out if my property can access the GPS satellites, is there a company I can contact who will help me find out if my property qualifies?
Hi Dudley,
GPS/Satellite coverage is available for most of North America, but it is difficult to accurately measure the exact satellite strength as the satellites are constantly moving, so you might get a good signal in the morning but poor signal in the evening.
There is an App available (GNSS View) that gives an overview of historical satellite positioning based of your current location (or a selected location).
Thanks,

Hey Dudley, thanks for the question. While there may be a company that specializes in this near you, I would start with some free resources to get a baseline. Depending on which device you have, the app store should have apps available (like this one) that can give you signal strength info for the various constellations.
Move around your house and check at a few times throughout the day to get an idea of the average signal strength available around you. If it looks good, it would be a matter of making sure your Luba install and reference station are positioned properly to avoid signal dropouts. I hope this helps.
