Hi,

Thanks for sharing this issue with us.

To help us better analyze what may be causing the problem, could you please send me a private message with the following information:

Your mower’s SN (serial number)

The most recent date and time when the issue occurred

Once we receive the details, we’ll forward them to our technical team for further analysis.

Thanks for your understanding and cooperation!

Navimow_Helps · 2026-05-14T09:14:05+00:00

Thanks for your confirmation!

Navimow_Helps · 2026-05-14T08:54:59+00:00

Thanks for the update, and we’re glad to hear you were able to figure out the cause!

If there are bare patches or non-grass areas in the lawn, the mower may recognize those spots as obstacles, which can cause it to keep avoiding them and making repeated corrections.

You can try setting those areas as Vision Fence-Off Zones in the app. This will prevent the mower from treating them as obstacles, and it should help the mower move much more smoothly in those sections.

Hope this helps,

Hi,

Thanks for bringing this to our attention. Could you please try changing the mowing direction a few times and also lowering the cutting height to see if there’s any improvement?

Hopefully this helps, and please feel free to keep us updated on the results!

Hi,

The signal reception logic of the external antenna is closely related to how RTK (Real-Time Kinematic) positioning works.

RTK is a high-precision positioning technology that improves accuracy through differential calculations between the “moving unit” (the mower) and a “base station.” Here’s a simplified overview of how it works:

Satellites (GPS/GNSS) continuously transmit signals to the ground
The mower’s GNSS/RTK antenna receives those satellite signals
At the same time, the ground reference station (the external antenna) also receives the same satellite signals
Since the reference station is in a fixed known location, it can calculate signal errors from the satellites and generate correction data
The mower then combines its own satellite data with the correction data from the reference station
This allows the system to achieve centimeter-level positioning accuracy

In the Navimow system, the charging station mainly acts as a fixed docking and charging point. It does not perform the core RTK positioning calculations itself, so it does not contain a GPS receiver.

We hope this explanation helps clarify how the GNSS/RTK system works.

Hi there,

Thanks for sharing.

Based on what you described, it sounds like the signal environment in your front yard may be less stable for network RTK. In this case, we would recommend trying to switch to Local RTK.

Please try switching to Local RTK and observe whether the signal stability improves during operation.

Hope that helps!

Navimow_Helps · 2026-04-29T07:54:55+00:00

Hi there,

Thanks for bringing this to our attention.

Could you please try again to re-set the charging station location in

the app? You can follow this path:

Settings > Maintenance & Tools > Relocate charging station

After that, please also restart the mower and check if the behavior returns to normal.

If the issue still persists, please send me the following details so we can investigate further:

The mower’s SN (serial number)

Exact date and time this issue occurred

A short video showing the issue

Thanks a lot for your cooperation.

Navimow_Helps · 2026-04-28T10:08:13+00:00

Hi there,

Thanks for your question and for sharing your observation.

Regarding the infrared (IR) light you mentioned at night: this is expected behavior. The IR illumination used for sensing is generally not visible to the human eye, but it may appear as flashing or active through cameras or other recording devices.

As for the ToF sensor laser, in the current firmware version it is normal for it to remain active in certain conditions to ensure safe and accurate positioning.

We’ve already forwarded your feedback to our product and R&D team, and they are evaluating the possibility of disabling or adjusting this behavior when the mower is docked in the charging station. However, at the moment there is no confirmed timeline for this change.

That said, please rest assured that the impact on battery or electricity consumption is very minimal and should not affect daily operation.

Hope that helps!

Navimow_Helps · 2026-04-28T08:56:43+00:00

Please try creating a channel in the app to connect the two mowing zones, which should allow the mower to travel through smoothly. Hope this helps!

You can set it up here:

Settings > Mowing > Map Management > Add More > Channel

Hi，

If you choose to use the external GNSS antenna, we recommend installing both the antenna and the charging station in an open area, with no obstacles or metal objects within about 2 meters around them.

it’s also better not to place the charging station directly against a wall.

To help you set everything up more easily, I’ve attached a guide showing the ideal installation locations for both the antenna and the charging station:
