摘要： A site positioning system for an underground machine includes a first prism coupled with the underground machine, a second prism operatively coupled with the underground machine, a primary total station, and a reference prism may be in communication with the primary total station. A positioning controller is configured to control, responsive to receiving a High Accuracy Machine Position mode, the primary total station to monitor the first prism and the second prism and transmit a first prism position and a second prism position, respectively, to the positioning controller; control, responsive to receiving a Low Accuracy Machine Position mode, the primary total station to monitor the first prism and transmit the first prism position to the positioning controller; determine, responsive to receiving a Reference Prism Measurement mode, whether a reference prism measurement has been completed, and present positioning information for the machine based on one or more of the prism positions.
