A system comprises a mobile machine including a first portion and a second portion, a positioning receiver coupled with the first portion of the mobile machine, a sensor for determining a position of the first portion of the mobile machine relative to the second portion of the mobile machine, and one or more computing devices. The one or more computing devices are configured to use information from the positioning receiver to determine a geographic location of the positioning receiver, use information from the sensor to determine a position of the first portion of the mobile machine relative to the second portion of the mobile machine, and adjust a navigation point offset according to the position of the first portion of the mobile machine relative to the second portion of the mobile machine, the navigation point offset being a difference in location between the positioning receiver and a navigation point.
