RTK vs LiDAR Robot Mower: Which Navigation Wins?

Updated October 3, 2026

Pick LiDAR if your yard has trees, tall hedges or buildings close to the lawn. Pick RTK if the lawn is open to the sky. If your budget allows, a hybrid that uses both is the safest bet, because each covers the other's weak spot.

How RTK works

RTK mowers fix their position from satellites, corrected by a reference signal. That signal comes from an antenna you mount in the yard or from a network service. Accuracy is excellent with open sky and drops under tree cover or beside tall walls.

61 models in our catalog use RTK or satellite positioning, and 26 of them list a separate base station or antenna as required.

How LiDAR works

LiDAR mowers scan their surroundings with a laser and build a map from what they see. They don't need the sky, so shaded yards and narrow side passages work fine. They do need recognizable features nearby, so a wide open field gives them less to lock onto.

33 models in our catalog list LiDAR.

Hybrids

9 models combine LiDAR with RTK. The mower uses satellites in the open and the laser map under trees. That's why most brands put the hybrid at the top of their range.

Our call

For a typical suburban yard with a couple of trees, LiDAR or a hybrid. For a big open lawn with nothing taller than a fence, RTK gives you the most coverage per dollar.

Questions people ask

Is LiDAR better than RTK for a robot mower?

Under trees and beside buildings, yes. In open lawns RTK is just as accurate and often cheaper per acre.

Does an RTK mower need an antenna?

Some do and some use a network RTK service instead. 26 models in our catalog list a separate base station or antenna as required.

Can a LiDAR mower work at night?

LiDAR doesn't depend on daylight to measure distance. Check the maker's notes on whether the camera features also work in the dark.

What is a hybrid robot mower?

One that combines RTK with LiDAR, so it navigates by satellites in the open and by laser mapping under trees.
