Abstract
A method for positioning a mobile object in an underground tunnel includes the steps of determining horizontal progression of a mobile object in an underground tunnel from a preceding position estimate or an initial position of the mobile object; determining horizontal position of the mobile object on the basis of a floor model of the tunnel and the estimated horizontal progression of the mobile object; and generating a three-dimensional position indicator on the basis of the horizontal position of the mobile object and a three-dimensional model of the tunnel.
