Mean errors are within certain ranges what means imprecision in their estimation. Measurements taken to different landmarks can be subjectively diversified. Measurements errors affect isolines deflections. The type of the relation: observation error ? line of position deflection, depends on isolines gradients. All the mentioned factors contribute to an overall evidence to be considered once vessel?s position is being fixed. Traditional approach is limited in its ability of considering mentioned factors while making a fix. In order to include evidence into a calculation scheme one has to engage new ideas and methods. Mathematical Theory of Evidence extended for fuzzy environment proved to be universal platform for wide variety of new solutions in navigation.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Terrestrial Navigation, Fuzzy Evidence, Positioning System, Mathematical Theory of Evidence (MTE), Isolines, Position Fixing, Pseudo Belief Structure, Dempster Transformation} }
