Celestial Video Courses

5 steps to fix a position with a sextant:

1. Measure the angle between the horizon and a celestial object (e.g. the sun) and note the exact time of observation ("Ho")
2. Choose an Assumed Position ("AP") in your vicinity for which the direction to the sun ("Azimuth") and the angle you should have measured had you been at the AP ("Hc") are given in the tables at the given time
3. Compare the two angles. The difference in minutes (Ho-Hc) is how far you are from the AP in nm ("Intercept"), either closer or further away from the sun.
4. Draw your AP, Azimuth and Intercept into your chart. Your position is a along a line perpendicular to the Azimuth ("Position Line")
5. Two Position Lines give your Fix
