Abstract

A robotic lawnmower system (200) comprising a charging station (210) and robotic lawnmower (100) arranged to operate in an operational area (205), wherein the charging station (210) comprises a communication interface (213) comprising a first interface (213 A) for establishing an internet connection and a second interface (213B) for transmitting RTK correction data to the robotic lawnmower (100) and wherein the robotic lawnmower (100) comprises a satellite navigation receiver (190) and a communication interface (115 A) for receiving RTK correction data from the charging station (210), and wherein the controller (211) of the charging station (210) is configured to receive RTK correction data through an internet connection via the first interface (213 A) and to transmit the RTK correction data to the robotic lawnmower (100) via the second interface (213B). And wherein the controller (110) of the robotic lawnmower (100) is configured to receive the RTK correction data from the charging station (210) via the communication interface (115 A) and to determine a position for the robotic lawnmower (100) based on the received RTK correction data and the satellite navigation receiver (190).
