- I've been looking at some high level overviews of celestial
- navigation. It seems that they only use the sextant to read the angle
- to the horizon and establish a circle of position. Then they use a
- second object (and circle of position) for a fix or running fix. I
- started wondering why they don't take the bearing to the celestial
- object to determine their location on the circle of position. Surely,
- adding a handheld compass to a sextant wouldn't be difficult and it
- would allow a fix based on a single celestial object. Is this ever
- done? Is there a good reason why not or is it just tradition?
