Abstract

A robotic work tool system (200) comprising a robotic work tool (100) arranged to operate in an operational area (205), and the robotic work tool (100) comprising a controller (110), a memory (120), a satellite navigation sensor (175) and one or more additional navigation sensors (180), and wherein the memory is configured to store a map of the operational are, said map application including a list of features, and wherein the controller (110) is configured to receive (510) sensor input from the satellite navigation sensor (175), the sensor input indicating a satellite position for the robotic work tool (100), determine (520) if the satellite position is a reliably determined, and if not so, determine a current position of the robotic work tool (100) by receiving sensor readings from the distance sensor (180), finding a matching feature in the list of features, the matching feature having a stored position, determine a distance to the feature and determining the current position based on the position of the matching feature and a distance to the feature.
