For the best positioning accuracy and mowing performance, it is strongly recommended to keep the antenna at a
distance that equals or above the height of a building or tall trees.
Our Exact Fusion Locating System (EFLS) uses multiple satellite-based system, such as GPS, BeiDou, GLONASS, Galileo, which
improves the positioning accuracy to approximately 2 cm. However, the accuracy crucially relies on the GNSS signal, which can be
weakened by the following:
Blocking
If there is anything on or surrounding the GNSS antenna, charging station and/or the mower, the signal will be weakened or
blocked.
Solution: DO NOT install the changing station and GNSS antenna under a roof, tree or anywhere that may block the signal. You
can also choose to buy the antenna extension kit and install the antenna on the roof.
Signal Interference
Signals from the satellite are transmitted to the antenna after being reflected by the wall, instead of directly from the air. This is
called Multipath Eect.
Solution: install the antenna far from the house to get rid of the multi-path eect. If your house has glass walls (or other walls
with smooth surface), please leave more distance.
Long Distance or Large Lawn
The communication module's transmission power gets weakened with long distance.
