Robotic lawnmower system and method for providing positioning utilizing several GNSS correction service sources

Abstract

A method for use in a robotic lawnmower system comprising a robotic lawnmower 100 arranged to operate in an outdoor operational area 205, the robotic lawnmower comprising a satellite navigation sensor and being arranged to operate based on a GCS source. The method comprises the robotic lawnmower receiving error correction data for satelbte navigation from a GCS source through the communication interface 115 and determine 410 a current position based on the received error correction data and the satellite navigation sensor 175, wherein the method further comprises navigating 420 based on based on the satellite navigation sensor 175 or based on the satellite navigation sensor 175 in combination with received error correction data from a first GCS source 245-1, determining 430 that operating conditions have changed, and in response thereto navigating 440 based on based on the satellite navigation sensor 175 in combination with received error correction data from a second GCS source 245-2.
