RegisterUserName said:. This location is called the ground position GP. GP can thus be stated in terms of celestial…. Navigation, science of directing a craft by determining its position, course, and distance traveled.
Navigation is concerned with finding the way to the desired destination, avoiding collisions, conserving fuel, and meeting schedules. History at your fingertips.

Conciliator Member. Oct 25, 4, One of the many problems I have with these things is that I always feel caught between answering the question as what theoretical ideal system I would like to see, vs.
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.

I killed the king of deceit. Wake me up in Anarchy. I guess somewhere in the middle? I guess the way I look at it is socialist programs are one way to address either the flaws in the capitalist system or to address the flaws in the government.
So there might be some things that I think ideally could work within a capitalist society but we just suck so we have to find other solutions.

All of these instruments may be termed "sextants". Attached to the frame are the "horizon mirror", an index arm which moves the index mirror , a sighting telescope, sun shades, a graduated scale and a micrometer drum gauge for accurate measurements.
The scale must be graduated so that the marked degree divisions register twice the angle through which the index arm turns.
The necessity for the doubled scale reading follows by consideration of the relations of the fixed ray between the mirrors , the object ray from the sighted object and the direction of the normal perpendicular to the index mirror.
This is the case shown in the graphic alongside. Traditional sextants have a half-horizon mirror, which divides the field of view in two.
On one side, there is a view of the horizon; on the other side, a view of the celestial object. The advantage of this type is that both the horizon and celestial object are bright and as clear as possible.
However, one has to sweep the celestial object to ensure that the lowest limb of the celestial object touches the horizon. Whole-horizon sextants use a half-silvered horizon mirror to provide a full view of the horizon.
This makes it easy to see when the bottom limb of a celestial object touches the horizon. Since most sights are of the sun or moon, and haze is rare without overcast, the low-light advantages of the half-horizon mirror are rarely important in practice.
In both types, larger mirrors give a larger field of view, and thus make it easier to find a celestial object. In large part, this is because precision flat mirrors have grown less expensive to manufacture and to silver.
An artificial horizon is useful when the horizon is invisible, as occurs in fog, on moonless nights, in a calm, when sighting through a window or on land surrounded by trees or buildings.
There are two common designs of artificial horizon. An artificial horizon can consist simply of a pool of water shielded from the wind, allowing the user to measure the distance between the body and its reflection, and divide by two.
Another design allows the mounting of a fluid-filled tube with bubble directly to the sextant. Most sextants also have filters for use when viewing the sun and reducing the effects of haze.
The filters usually consist of a series of progressively darker glasses that can be used singly or in combination to reduce haze and the sun's brightness.
However, sextants with adjustable polarizing filters have also been manufactured, where the degree of darkness is adjusted by twisting the frame of the filter.
Most sextants mount a 1 or 3-power monocular for viewing. Many users prefer a simple sighting tube, which has a wider, brighter field of view and is easier to use at night.
Some navigators mount a light-amplifying monocular to help see the horizon on moonless nights. Others prefer to use a lit artificial horizon.
Most sextants also include a vernier on the worm dial that reads to 0. Since 1 minute of error is about a nautical mile , the best possible accuracy of celestial navigation is about 0.
At sea, results within several nautical miles, well within visual range, are acceptable. A highly skilled and experienced navigator can determine position to an accuracy of about 0.
A change in temperature can warp the arc, creating inaccuracies. Many navigators purchase weatherproof cases so that their sextant can be placed outside the cabin to come to equilibrium with outside temperatures.
The standard frame designs see illustration are supposed to equalise differential angular error from temperature changes.
