Abstract
A positioning system and method for determining a position of a machine are disclosed. The system may have an optical sensing device configured to generate determined shape data associated with a portion of the worksite at the position of the machine. The system may have a first signal device configured to transmit a radio frequency signal and receive a response signal. The system may have a second signal configured to receive the transmitted radio frequency signal and transmit the response signal. The system may have a controller in communication with the optical sensing device and at least one of the first and second signal devices. The controller may be configured to determine an approximate position based on the radio frequency signal and the response signal, identify a reference shape data corresponding to the determined shape data, and determine the position based on the approximate position and the reference shape data.
