A method for determining a position of a machine (10) in a worksite (20) is disclosed. The method comprises determining input data (102) from a Lidar survey by a Lidar unit (32) on the machine (10). The input data (102) is associated with distances between the Lidar unit (32) and respective light- reflective points in the worksite (20). The method further comprises communicating by a radio-frequency communication between a first signal device (34) at a known location (35) within the worksite (20) and a second signal device (36) located on the machine (10). The method further comprises determining position data for the machine (10) based on at least the radio frequency communication, and determining a position of the machine based on the position data and the input data (102). Also disclosed is a system (30) for performing the method.
