Abstract: Systems and methods for providing direction guidance to a traveler navigating off-road are disclosed. In some embodiments, different modes of direction guidance are provided depending on a deviation distance from a pre-recorded, off-road track. A pre-recorded track can be generated from an ordered list of locations. A real-time deviation distance between the traveler and the track can be determined. Based at least in part on the real-time deviation distance, the system determines whether the traveler is on track. If the traveler has deviated, the system may provide direction guidance toward a location where the traveler deviated from the track. The system may determine that the traveler has deviated too far from the track and provide direction guidance toward a closest point on the track. The system can display direction guidance on a vehicle-mounted display and/or on a mobile device.
