Abstract: A system for determining an error in a sensed position of a machine includes a position sensing system, a dead reckoning system, and a controller. The controller is configured to determine a difference between a sensed position and a calculated position determined by dead reckoning. The difference is compared to an error threshold defining a maximum acceptable distance between the sensed position of the machine and the calculated position of the machine and an error signal generated if the difference exceeds the error threshold. A pair of offset dead reckoning processes may be used.

Abstract: A system having a controller is provided. The controller receives a signal indicative of an actual position and an actual orientation of a machine on a worksite, from a position detection module. The controller determines a first view of the machine on the worksite. The first view shows the actual position of the machine and a target position of the machine. The target position is located on a bucket circle. The controller determines a second view of the machine on the worksite. The second view has a first and a second indicator. The first indicator is indicative of the actual position and the actual orientation of the machine. The second indicator is indicative of the target position and a target orientation of the machine and includes a target circle. The controller displays any one of the first view and the second view based, at least in part, on the actual position of the machine relative to the target position on a display unit.
