To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. All PTS classes are being delivered in an online format unless you are notified otherwise.
This course provides students with a means to navigate a vessel by terrestrial and celestial methods. The course contents include shape of the earth and the graticule system; plane sailing; parallel sailing; Mercator and great circle sailing; determining a vessel's position by using celestial bodies; and theory and practice of sextant. It is strongly recommended that students should review algebraic and trigonometric functions prior to taking this course.
This course isn't currently offered through BCIT Part-time Studies. Please check back next term or subscribe to receive email updates.
Upon successful completion of this course, the student will be able to:
Explain the concept of earth shape used for marine navigation.
Calculate the arrival and departure position, and determine course and distance using plane, parallel, and Mercator sailing.
