Analytical Model of Position Uncertainty of Ship's Plan Geometry in Integrated Navigation System
1 Maritime University of Szczecin, Szczecin, Poland
ABSTRACT: For safety reason it would be essential to apply uncertainty of ship's contour position in safety evaluation of maneuvers carried out on basis of INS (Integrated Navigation Systems) indications, instead of real dimensions of the ship's contour. The paper presents analytical method of ship's plan geometry (contour) uncertainty area determination. The model was used to determine uncertainty area of ship maneuvering in Świnoujście harbor for typical configuration of navigational equipment applied in existing pilot systems. The results of experiment were discussed. The model equations were derived from measurement error propagation theory. Potential application of uncertainty area as safety zone around ship contour was appointed.
