Husqvarna EPOS - How it works

Automower 550 EPOS – Satellite Navigation

Husqvarna EPOS (Exact Positioning Operating System) is a breakthrough technology for a new series of professional Automower® robotic lawn mowers. The satellite-based technology enables the mowers to work within virtual boundaries. This makes it an easy and flexible solution. Perfect for football pitches, golf courses, city parks, company real estates – and all other places that deal with changing circumstances and needs. Also, the absence of physical boundary wires means problem-free aerating, scarifying and turf repair.

Navigation satellites
Global navigation satellite system (GNSS) provides satellite signals to the mower and the reference station. A minimum of four satellite signals are needed for both the mower and the reference station. The following GNSS satellite systems are used: GPS, GLONASS, BeiDou and Galileo.

Satellite signals
Satellite signals are received by both the mower and the reference station. To achieve up to centimeter level accuracy a technique called RTK-GNSS is used. It enhances the precision of satellite position data.

Reference station
A fixed reference station is required to reach a high precision of the mower’s position. The reference station broadcasts correction data to the mower.

Correction data
Correction data from the reference station is required to operate the mower at all times and to keep a high level of accuracy of the mower’s position.

Charging station
The place where the mower automatically returns to recharge its batteries.

Stay-out zone
Define temporary or permanent stay-out zones by using the appDrive function in the mobile app to drive the mower around areas that shall not be mowed.

Virtual boundary
Define the mower’s work area by using appDrive function in the mobile app to drive the mower around the area that shall be mowed.

Mobile app
Use your mobile phone and the app to set up the installation, and define work areas and stay-out zones.
