This is the act of shooting a heavenly body such as the sun,
moon or stars in successive times to produce a line of position.
Taking the intersection of two lines of position (LOP) results in
a celestial fix, as shown below by the LOPs for the sun and
moon below. Positioning info from the
nautical almanac is
used to determine your location.
