an astronomical instrument for taking the altitude of the sun or stars and for the solution of other problems in astronomy and navigation: used by Greek astronomers from about 200 b.c. and by Arab astronomers from the Middle Ages until superseded by the sextant.
Yes, Orion is a prominent constellation used for navigation because its position in the sky remains relatively fixed and it is visible from both hemispheres. The three stars in Orion's belt are particularly useful as they point towards other important stars and constellations.
One characteristic that is not used to classify stars is their specific location in the galaxy. While stars are classified based on properties such as temperature, luminosity, and spectral type, their position within the Milky Way or other galaxies does not play a role in their classification. Instead, classification focuses on intrinsic properties that relate to their physical characteristics and evolutionary stages.

Look at the position of the stars. See what degree they are at and you'll know the time. That's how ships used to navigate. The position of the stars will allow a knowledgable observer to tell the time. The observable stars depends on location and time of the year.
Probably not. However, as it is an easy to identify grouping with several bright stars, it's certainly feasible that some of them were used on occasion by ships to help fix their position.
To retain friction bearings, devices such as bearing retainers, bearing cages, or bearing housings are typically used. These components hold the bearings in place within a machine or mechanical system to prevent them from moving out of position during operation.

The Phoenicians used the sun and stars to navigate
The compass triangulation method involves taking bearings of at least three known landmarks from your current position. By plotting these bearings on a map and where they intersect, you can determine your exact location. This method is effective for accurately pinpointing your position in the field.
The sailors used the positions of celestial bodies, such as the sun, moon, and stars, as a frame of reference for navigation at sea. By tracking these celestial bodies, sailors could determine their position and navigate their ships accordingly.
