Abstract: A positioning system for a machine is disclosed. The positioning system includes a satellite positioning unit to generate signals indicative of a location of the machine in a worksite and an inertial measurement unit (IMU) to generate signals indicative of a position of the machine. A controller is communicated with the satellite positioning unit and the IMU. The controller determines a first error value associated with a location of the machine based on signals received from the satellite positioning unit. The controller further determines a second error value associated with a location and a position of the machine based on signals received from the satellite positioning unit and signals received from the IMU, respectively. Further, a location of the machine is determined based on signals received from the satellite positioning unit and the IMU if the first error value is less than the second error value.

Abstract: A system for tracking a position of a cable attached between a power source and a machine in a worksite is disclosed. The cable is further coupled to a guiding device located in the worksite between the power source and the machine. The system includes a perception module disposed on the machine to detect a location of the guiding device. The system further includes a controller disposed to be in communication with the perception module. The controller determines the location of the guiding device with respect to a location of the machine and determines a distance between the guiding device and the machine. The controller further compares the distance with a first threshold distance and a second threshold distance and generates a warning if the distance is greater than the first threshold distance or smaller than the second threshold distance.
