Compass made good correction with MTE

Abstract

Imprecise and uncertain data dominate in maritime transportation. The Mathematical Theory of Evidence (MTE) [12, 14] extended to a possibilistic platform [16] enable processing the uncertainty. The Mathematical Theory of Evidence enables upgrading new models and solving crucial problems in many disciplines. The evidence combining scheme as a mechanism enabling enrichment of the initial data information context is useful in many cases. In nautical applications it can be used to make a fix and to evaluate its accuracy. The MTE delivers a new unique opportunity once one engages fuzzy values. Approaches towards a theoretical evaluation of tasks including imprecise data are to be reconsidered. A compass made good correction evaluation is one of such problems. To calculate the correction one has to know the direction towards a landmark or a celestial body. Taking two bearings to landmarks situated at opposite sides is also sufficient. Landmarks situated at counter bearings locations are not available very often. © 2012 Springer-Verlag.
