1 :: What is astrolabe?

Astrolabe is an instrument used to determine the altitude of celestial objects before the introduction of the sextant. The first recorded use by Greek astronomers in around 200 B.C.

2 :: What is local Hour Angle (LHA)?

The Local Hour Angle (LHA) is the angular distance to the Meridian of the celestial body's Geographical Position, as measured Westwards from the observer's local Meridian.

The Local Hour Angle is calculated from the Greewich Hour Angle (GHA) of the celestial body and the Longitude of your Estimated Position in the following way:-

☛ LHA = GHA - Longitude, if the Longitude is West
☛ LHA = GHA + Longitude, if the Longitude is East

3 :: What is CC or Compass Course?

CC or Compass Course is the course to steer which has been corrected for current, variation, and deviation.

4 :: What is copernicus?

Copernicus is 1473-1543, Polish astronomer credited with disproving the Ptolemaic System.

5 :: What is doldrums?

Doldrums is the Inter-tropical Convergence Zone (or ITCZ) a belt of very still air between 5 degrees north and 5 degrees south of the equator.

6 :: What is horizon?

Horizon is the apparent line, for an observer where the earth’s surface and the sky meet. Also a circle formed on the celestial sphere by a plane tangent to a point on the Earth's surface.

7 :: What is north Magnetic Pole?

North Magnetic Pole is the northerly point toward which a compass' needle always points, the north of the earth’s magnetic field as opposed to the geographic north pole

8 :: What is standard port?

Standard port is a port for which the Tide Tables give full details and from which Secondary Port details con be extrapolated. Strait is a narrow channel of water connecting two larger bodies of water.

9 :: What is actual depth?

Actual depth is the true depth of water as opposed to a predicted depth. Tidal height from table added to the charted depth.

10 :: What is artificial Horizon?

If sight of the natural Horizon is not available, an Artificial Horizon is some means by which an observer can refer to a horizontal plane through his position. With a marine sextant, it is common to use a mirror in the horizontal plane. The angle between the celestial body as seen in the sky and as reflected in the mirror is measured with the sextant. Halving this angle gives the Altitude of the celestial body above the Horizon.

11 :: What is bearing?

Bearing is the compass reading taken of a object in relation to the observer.

12 :: What is compass Rose?

Compass Rose is is a design on a chart that shows direction. It points which way is north, south, east, west, and some intermediate directions.

13 :: What is drift?

Drift is the speed in knots of the effect of current or tide on a vessel's progress.

14 :: What is horizon Glass?

Horizon Glass is or Horizon Mirror half clear glass half mirror, on a sextant it allows the observer to view the horizon at the same time as a reflection of whatever is showing in the Index Mirror. Read more:

15 :: What is ptolemy?

20 :: What is westerlies?

Westerlies is are the prevailing west-to-east winds of the middle latitudes of both hemispheres on Earth.

21 :: What is Line Of Position, LOP?

Line Of Position, LOP is a line drawn on a chart on which the position of the vessel must lie. The line deduced from either a compass bearing of a mark or a sight reduction. A minimum of two or preferably more are necessary to establish a fix.

22 :: What is fathom?

Fathom is an old fashioned unit of measurement to measure depth, approximately equal to 6 feet or 1.8 meters.

23 :: What is course made good?

Course made good is the direction in which the vessel is actually traveling as opposed to the direction in which it is pointing. Corrections is alterations made to charts to update navigational information.

24 :: What is celestial navigation?

Celestial navigation is a method of navigating by referring to the stars or other objects in the sky.

25 :: What is azimuth Quadrant?
