The course offers a throughout understanding of the procedures that are relevant for the maritime navigation in terms of voyage planning and watchkeeping. It covers competences 1.1, 1.2, 1.3, 1.4, 1.5 of the IMO Model Course for Master and Chief Mate
The course offers a throughout understanding of the procedures that are relevant for the maritime navigation: a theoretical part allows to focus on the physics, geodesy and astronomy items related to navigation, while an operational part will focus on the methods that are necessary to carry out a reliable voyage planning and a correct execution, taking into account the use of nautical charts and publications, ship's routeing and ship's reporting systems. The position fixing will be analysed both in terms of coastal and celestial navigation considering the support provided by proper Aids to Navigation and the use and control of traditional instruments such as the magnetic and gyro compass and the marine sextant. The IAMSAR procedures are also taken into account.
The course offers a thorough understanding of the procedures that are relevant for the maritime navigation: a theoretical part allows to focus on geodesy, cartography, astronomy items related to navigation and statistical approach to the measurements. An operational part will focus on the methods that are necessary to carry out a reliable voyage planning and a correct execution in any condition, taking into account the use of nautical charts and publications, ship's routeing and ship's reporting systems. The position fixing will be analysed both in terms of coastal and celestial navigation considering the support provided by proper Aids to Navigation and the use and control of traditional instruments such as the magnetic and gyro compass and the marine sextant. The IAMSAR procedures are also taken into account.
The course aims to offer a great part of the learning outcomes set in the STCW Table A-II/2 “Specification of minimum standard of competence for masters and chief mates on ships of 500 gross tonnage or more”, function: Navigation at the management level.
At the end of the course the students are expected to:
Apply the pertinent methods for a reliable passage planning in compliance with the international regulations in all conditions
Apply the pertinent procedure for a safe watchkeeping in compliance with the international regulations in all conditions
Being aware of the traditional navigation equipment operation and limitations in all conditions
Respond to emergencies in terms of SAR
Frontal lessons, group work, exercises, lab activities.
Geodesy: terrestrial sphere, coordinate systems, reference systems and transformations between them. Horizontal and vertical datum.
Cartography: Cartographic projections and deformations. Nautical chart projections and Nautical position. Loxodrome and geodesics.
Statistical approach to measurements: source of errors, statistical indices, error propagation by linear equations.

The exam is oral but a short essay on astronomical fix with the use of sight reduction tables is required. The latter is assigned to each student that enrols for the exam by Aulaweb
The assessment is based for the greatest part on the oral exam, for which the student is expected to demonstrate a comprehensive awareness of the subjects both in technical terms and in relation to the maritime international regulation. The correct use of specific lexicon is taken into account.
The essay is important for the evaluation of the celestial navigation part also in terms of the application of calculation schemes and procedures.
