Principles of Celestial Navigation

The Intercept Method » Intercept Method Overview » Exercise

Before we move on, try the exercise below and match each definition to its proper term.

Match each term below to its appropriate definition.

1. Point at which a Line of Position intercepts the azimuth line
2. An approximate position close to where we think we are
3. Line representing all of our possible locations as determined from a celestial observation
4. Sextant measurement plus some corrections
5. Direction to the geographic position of the celestial object if we were exactly at the Assumed Position
6. Altitude the celestial object would have if viewed exactly from the Assumed Position

If you struggled with any of these definitions, you might wish to review the previous pages. You'll learn more about how these values are used in celestial navigation as you continue through the module.
