Abstract: A control system for a host work machine operating at a worksite with one or more other work machines is disclosed. The control system has a communication device operatively connected to the host work machine, and a controller. The controller has stored in a memory thereof one or more parameters associated with a predetermined task and is configured to autonomously control the host work machine to perform the predetermined task. Upon the host work machine encountering a need for assistance, the controller is further configured to communicate a request for assistance to at least one of the one or more other work machines via the communication device.

Abstract: The boundary tracking system has a plurality of signal transmitting devices located to represent at least one boundary of a work site. The boundary tracking system also has a receiving device configured to receive signals transmitted from one or more of the plurality of transmitting devices and to generate an output based on the received signals. The boundary tracking system also has a controller configured to determine a location of at least one of the plurality of transmitting devices based on the output from the receiving device.

Abstract: A data acquisition system for a work machine has at least one sensor disposed on the work machine. The at least one sensor is configured to produce a signal indicative of an operating parameter of the work machine. The data acquisition system also has an identification module disposed on the work machine and configured to receive an input corresponding to a machine operator. The data acquisition system further has a controller disposed on the work machine and in communication with the at least one sensor and the identification module. The controller is configured to record and link the signal and the input. The data acquisition system additionally has a communication module disposed on the work machine and in communication with the controller. The communication module is configured to transfer the recorded and linked signal and input from the controller to an off-board system.

Abstract: A positioning system for an entity at a work site may include an RFID device including a memory configured to store a position of the entity and at least one other characteristic associated with the entity. A transmitter associated with the RFID device can emit a signal including information relating to the position of the entity and to the at least one other characteristic of the entity.

Abstract: A system for tracking entities at a work site includes an antenna having a scanned boresight. A controller may be configured to determine a relative angle between a reference associated with the antenna and a source of radiation based on a relationship between boresight orientation and relative power values of a signal received by the antenna from the source of radiation for two or more boresight orientations of the antenna.

Abstract: An apparatus and method are disclosed for determining the position of a vehicle at or near the surface of the Earth using navigation signals from a satellite-based navigation system. Precise position estimates are achieved by reducing effective receiver noise. A plurality of receiver means each compute a pseudorange for each satellite. A signal optimizer then uses the pseudoranges from each receiver means to compute an optimal pseudorange for each satellite. A processor means computes a vehicle position from the optimal pseudoranges.
