From the background information supplied by the inventors, news correspondents o btained the following quote: “A farming machine may include a vehicle coupled to an implement, and the vehicle pushes or pulls the implement to perform various farming operations (e.g., tilling, planting seeds, treating plants). Typically, the farming vehicle has a location sensor (e.g., global positioning system senso r) that determines the location of the farming vehicle. As the farming vehicle m oves, the location sensor collects location data and a heading (e.g., an orienta tion of the farming machine) of the farming vehicle is calculated based on chang es in location data corresponding to the motion of the farming vehicle. However, the heading of the farming vehicle cannot be determined when the farming vehicl e is stationary because there is no change in the location data or the determine d heading is inaccurate when the farming vehicle is moving at a speed below a th reshold speed because the error or noise in the location data is greater than th e measured changes in the location data. Furthermore, the implement may be attac hed to the farming vehicle with a pivot hitch that allows the implement to move side to side about the pivot hitch, so the heading of the implement may not be a ligned with the farming vehicle. Therefore, the movements of the farming vehicle and the implement are difficult to predict when the farming machine is stationa ry or moving below the threshold speed, which can lead to damage or accidents.”
