# Altitude Intercept

* Altitude Intercept* is calculated using

**from Section I, and**

*ho***from Section IV. It is a measure of the distance from the Assumed Position to the Line of Position. To determine the direction of the Line of Position, we investigate if**

*hc***is greater than**

*ho***. If so, then the Line of Position lies between the Assumed Position and the Celestial Body. However, if**

*hc***is less than**

*ho***, then the Line of Position lies behind the Assumed Position. The mnemonic “ho-mo-to” traditionally serves as a reminder of this rule.**
