1. The curves are known as " lines of position " or LOP. 2. Circles, arcs, and hyperbolae of positions are often referred to as lines of position . 3. So he planned his final approach to follow a line of position directly to his destination. 4. Multiple lines of position can be intersected to obtain a position known as a celestial fix. 5. The method yields a line of position ( LOP ) on which the observer is situated. 6. It was phase comparison at this common frequency that resulted in the hyperbolic lines of position . 7. If the navigator draws two lines of position , and they intersect he must be at that position. 8. A navigator shoots a number of stars in succession to give a series of overlapping lines of position . 9. That height can then be used to compute distance from the subpoint to create a circular line of position . 10. In navigation, the determination of a " lines of position are drawn radiating from the landmarks along the reverse angle.
