Calculation of intercept and direction of position line - Star as the celestial body

This video explains the procedure for the calculation of Intercept and the orientation of the position line using the Marc St. Hilaire method in the topic of celestial navigation. The example uses star as a celestial body and this is example 2 in the series. Contents of this video will benefit mariners preparing for exams (written and oral examinations).
