Abstract: Navigation appliance for determining and indicating the position of a pedestrian, in particular a golfer on a golf course, which appliance is portable and has a navigation device, a memory device, an input device and a display device which are connected to an arithmetic device, where the navigation device comprises a relative-position determination device which has a motion sensor and is designed to estimate a distance covered on foot by the golf player. The invention also extends to a method for navigation using a relative-position determination device, having the following steps: measurement of acceleration values using a motion sensor arranged on a pedestrian, in particular on a golf player; storage of the acceleration values over a time period; and calculation of walking speed and/or distance walked for the user using an estimation model. The invention also relates to a method for navigation in a golf game with reading and display of a sample game progression.
