Unit Code: DNS485

Unit Name: Practical Navigation

Description: Terrestrial navigation is the method of navigation used by mariners that uses landmarks as reference points and ship’s speed along with tides and currents. This is the opposite of celestial navigation, which plots positions in relation to the stars. Mariners use both systems of navigation for accuracy.

Learning Target Outcomes: Upon successful completion of this unit DNS485, the students is expected to: • Calculate the average speed and set & the drift of the current experienced during the day • Analyze compass errors by terrestrial and astronomical observations • Discuss terrestrial and astronomical position lines and position circles • Understand the Intercept method of sight reduction of the Sun • Determine ships position by use of dead reckoning including taking into account winds, currents and estimated position • Calculate height at a time between high and low waters at standard ports or time when the tide reaches a specified time with tide tables and tidal curves.
