Celestial Navigation · Line of Position — Plotting
After computing intercept and azimuth, how is the celestial line of position drawn relative to the azimuth line?
- AAlong the azimuth from the GP
- BParallel to the azimuth at the assumed position
- CPerpendicular to the azimuth, through the point laid off along the azimuth by the intercept distance✓ Correct
- DAt 45° to the azimuth
Explanation
From the assumed position, lay off the azimuth (Zn), measure the intercept toward or away from the body along it, and draw the LOP perpendicular to the azimuth at that point. The LOP is a short segment of the very large circle of equal altitude.
