If we imagine a compass, the acute angle between the north C (3600) or the south Yu (1800), located in one of the quarters of the compass, and this line is the desired rumba.Its index will indicate the direction of the light, that is, for example rYuV will be located in the second quarter.
marked on the compass rumba wide and narrow triangles.There are only 32. The angle between adjacent equal to 11 ° 15`.The magnitude of this angle is called.One EPIRB - 11 ° 15`, two rumba 2h11 ° 15` = 22 ° 30`, etc.
calculus in compass points used in marine navigation.Areas to the north, south, east and west are called the principal.The rest of the names of the main combined, eg NW.Also designated rumba and Latin letters, where N - north, S -Yug,
E - east, W - west.
used to navigate 32 rumba.In meteorology, the direction is determined from the center of the visible horizon to the point of its circumference.It is important only visible horizon, which is divided by 16. In surveying EPIRB - the angle created geographic meridian line with this, it does not exceed 900.
Calculation rumba begins with the definition of the compass on the compass, and the postponement of the meridian line the desired value.For example, 3 rumba to the northeast is 3h11015` = 33045` east of the northern meridian.
rumba used in surveying to determine the direction and orientation of lines.The value is also referred to by the letter r, and is accompanied by a letter designation direction and angle digital signage, for example: E: r15015`.This means that the line will be determined by the direction 15015` east of the southern meridian, iein the second quadrant of the compass.
Recently, however, to determine the direction of the line and terrain orientation in most cases, a simple degree system.
