Political Sextant Navigation menu VideoPolitical Sextant Quiz People who find themselves in worse positions are generally there because of their own choices and actions. This makes it easy to see when the bottom limb of a celestial object touches the horizon. For example, when a sextant is used on a moving ship, the image of both horizon and celestial object will move around in the field of view.

The angular distance of the star above the horizon is then read from the graduated arc of the sextant.
From this angle and the exact time of day as registered by a chronometer, the latitude can be determined within a few hundred metres by means of published tables.
Sextants were first developed with wider arcs for calculating longitude from lunar observations, and they replaced octants by the second half of the 18th century.

I took my "disagree" to "agree" and it gave me Trotskyism. Is this good? The Adder Member. Oct 25, 9, Also, I expected nothing less than your highest agree being less than fifty percent somehow.

Guess we're all anarcho-feminists now! Parthenios said:. It's pretty good, I'd say! You don't have any of the tankie options, and you hate the fashies.
I'd be interested in if you think of yourself as a socialist or as a capitalist, given that Third Way appears to be the new Mystery Outcome now that we've figured out where Marxism-Leninism is coming from.

Star and planet sights are normally taken during nautical twilight at dawn or dusk , while both the heavenly bodies and the sea horizon are visible.
There is no need to use shades or to distinguish the lower limb as the body appears as a mere point in the telescope. The moon can be sighted, but it appears to move very fast, appears to have different sizes at different times, and sometimes only the lower or upper limb can be distinguished due to its phase.
After a sight is taken, it is reduced to a position by looking at several mathematical procedures. The simplest sight reduction is to draw the equal-altitude circle of the sighted celestial object on a globe.
The intersection of that circle with a dead-reckoning track, or another sighting, gives a more precise location. Sextants can be used very accurately to measure other visible angles, for example between one heavenly body and another and between landmarks ashore.
Used horizontally, a sextant can measure the apparent angle between two landmarks such as a lighthouse and a church spire, which can then be used to find the distance off or out to sea provided the distance between the two landmarks is known.
Used vertically, a measurement of the angle between the lantern of a lighthouse of known height and the sea level at its base can also be used for distance off.
Due to the sensitivity of the instrument it is easy to knock the mirrors out of adjustment. For this reason a sextant should be checked frequently for errors and adjusted accordingly.
There are four errors that can be adjusted by the navigator, and they should be removed in the following order. After a year interregnum, the U.
Navy began training again in the sextant as back-up navigational devices as instructed by 30th Chief of Naval Operations inasmuch as it does not rely on electrical systems.
