The azimuth angle Az of the Sun or a celestial body (St) is depending on it's declination Dec and altitude Alt, and on the latitude Lat of the observer ( Astronomical/Nautical Triangle ): The angle of declination, δ is the angular displacement of the sun to the centre of the Earth and is given in degrees by: (1) where, m represents a day in a year i. Since the Earth is tilted on its axis and rotates every year, the angle of declination changes throughout the year. angle of inclination - (geometry) the angle formed by the x-axis and a given line (measured counterclockwise from the positive half of the x-axis) inclination geometry - the pure mathematics of points and lines and curves and surfaces The intensity of earth's magnetic field is maximum at its magnetic poles and minimum at the earth's magnetic equator. The angle between magnetic north and geographic north is defined as the magnetic declination or the angle of declination (refer to illustration). I can also find the angle of dip from the height but should I add or subtract it from the declinat The object of the Nautical Almanac is to provide, in a convenient form, the data required for the practice of astronomical navigation at sea. angle of inclination or dip; MAGNETIC DECLINATION declination is the angle between where a compass needle points and the true north pole. It should usually measure approximately 21°. To convert this true north heading to a compass heading, you have to subtract 10° from 44°, so the sunrise occurs at 34° on your compass. 5° during the Northern The declination of the Sun is the measurement of the angle between the Sun’s rays and the Earth’s equatorial plane. Most RECTA compasses are equipped with a fixed or adjustable declination correction.
