Abstract
A method for determining a position of a machine in a worksite is disclosed. The method may include determining, using a Lidar unit on the machine, input data. The input data may be associated with distances between the Lidar unit and respective light-reflective points in the worksite. The method may also include transmitting a radio-frequency communication between a first signal device at a known location within the worksite and a second signal device located on the machine. Further, the method may include determining position data for the machine based on at least the radio frequency communication. The method may also include determining a position of the machine based on the position data and the input data.
