ABSTRACT

Mathematical Theory of Evidence, also known as Belief Theory or Dempster-Shafer Theory, exploits belief and plausibility measures and operates on belief assignments or belief structures. The theory also offers combination mechanism in order to increase the informative context of the initial evidence. The evidence is meant as a collection of facts and knowledge. In navigation, facts are results of observations such as taking bearings, distances or horizontal angles. Thus a combination scheme is expected to enable position fixing of the ship.
