Hi, I did answer, not sure why you didn't receive a notification. Sending my answer below, but generally it is not just down to the number of satellites but the position of the satellites and the position of the RTK station. So if you are using the RTK station and not iNavi, then the positioning is crucial to obtaining the correct number and location of satellites.
The specific number of satellites required for the Luba AWD Mini RTK antenna to function successfully isn't something I can provide with complete certainty. For this technical specification, it would be best to discuss directly with Mammotion, the manufacturer.
Generally, RTK GPS systems need a minimum of 4-5 satellites for basic positioning, but for optimal RTK precision (which is what makes these mowers effective), they typically perform best with 7+ satellites in view. However, the exact minimum threshold for the Luba specifically would be manufacturer-defined.
Thanks
Mark
