The definition of azimuth and the definition of bearing are strictly distinguished, so please fi

Azimuth: The horizontal angle from the northward direction of a certain point to the target direction line, calculated from the true meridian as the 'true azimuth';It is calculated from the magnetic meridian as the 'magnetic azimuth';It is calculated from the coordinate vertical line as the 'coordinate azimuth'.

The bearing angle is a plane angle, which is the angle between the straight line and the north-south direction line (see azimuth bar), and is still used to mark one of the two points of orientation. Unlike azimuth, the azimuth is calculated from north to south, and the angle value is between zero and 90 degrees. The direction angle is expressed by preceding the angle value with the words north and south, followed by the words east and west.

For example, in Figure 1, the observation point or origin of point O, the direction angle of Oa is 50 degrees north east), which is measured from the north in a clockwise direction, and the direction angle of ob is measured from the south in a counterclockwise direction to the east. The direction angle of OC is, and the direction angle of OD is. These four lines are in different quadrants, and the value of the table can be added to the prefix to indicate what quadrant the line is in, and also to indicate the direction in which it should be measured.

See Figure 1) The bearing angle is the same as the azimuth angle, and it also has the names of true direction angle, magnetic direction angle, and hypothetical direction angle according to the fact that the north-south line is true north-south, magnetic north-south, and hypothetical north-south.

For the same straight line, the direction of the straight line is also opposite due to the different starting and ending points. As shown in Figure 2, the straight line lp, if it starts from l, if it is the direction angle to p, then it starts from p and the direction to l is, if the former is called the forward direction angle, the latter is called the rear direction angle. On the contrary.

If PL is named as the forward direction, LP is the rear direction. The angles of the front and back angles are the same, but the suffix of the prefix must be changed, that is, n becomes s, or s becomes n; At the same time e becomes w, or w becomes e.

The direction angle generally refers to the angle formed by rotating the direction line of the target from due north or south as the starting direction with the observer's position as the center (generally referring to the acute angle), which is usually expressed as north (south) east (west) degrees.

Azimuth definition: The horizontal angle from the north end of the standard direction to a straight line in a clockwise direction is called the azimuth of the straight line. The value range of azimuth angle is 0° 360°.

From the north direction line du of a certain point, follow the clockwise direction to the eye

The horizontal angle between the marking lines is called the DAO azimuth. Edition.

Since each point has three different north-pointing direction lines, namely, true north, weighted magnetic north, and coordinate longitudinal north, there are three different azimuth angles from a certain point to a certain target.

1) True azimuth. The direction line pointing to the north pole at a certain point is called the true north direction line, and the meridian line is also called the true meridian. From the true north direction of a certain point, according to the clockwise direction to the target direction of the money between the sailor's angle, is called the true azimuth angle of the point. It is often used in precision measurements.

2) The earth is a large magnet, the position of the earth's magnetic poles is constantly changing, and the direction line pointing to the magnetic north pole at a certain point is called the magnetic north direction line, also called the magnetic meridian. The straight line between the magnetic south and magnetic north points on the north and south outlines of the topographic map is the magnetic meridian of the map. From the magnetic north line of a certain point, the horizontal angle between the clockwise direction and the target direction line is called the magnetic azimuth angle of the point.

3) Coordinate azimuth. From the north of the coordinate longitudinal line of a certain point, the horizontal angle between the money from the clockwise direction to the target direction is called the coordinate azimuth angle of the point.

Azimuth is widely used in surveying and mapping, geological and geophysical exploration, aviation, navigation, artillery firing, and troop marching. Different azimuths can be converted to each other.

The horizontal angle from the north end of the standard direction to the line in a clockwise direction is called the azimuth of the line.

I'm your dad hahaha

Azimuth refers to the reception of BAI by the satellite

The antenna is rotated 0° 360° in the water plane. When the azimuth angle is adjusted, the parabola, the dao, moves left and right in the horizontal plane.

Swing back. Usually the result we get by calculating the soft answer or in the data should be based on the standard of due north direction (about the south pole of the geomagnetic field), and adjust the direction of the satellite antenna to the east or west by an angle, which is the so-called azimuth angle.

Azimuth angle, also known as Azimuth Angle (AZ), is one of the ways to measure the angular difference between objects on a flat surface. It is the horizontal angle between the northward direction line of a certain point and the target direction line in the clockwise direction.

To put it simply, the azimuth angle from point A to point B in space is to move the origin of the north arrow to the position of point A, and the azimuth angle from point A to point B is the projection A of the north arrow rotating clockwise and the straight line AB on the horizontal plane'b'of the included angle. Range 0-360 degrees.

The azimuth angle is the horizontal angle between the northward direction of a point and the target direction line from the clockwise direction. It is expressed in degrees and density. It is often used to determine bearing, indicate targets, and maintain the direction of travel.

Coordinate azimuth: The angle between a straight line and the coordinate principal axis in a planar Cartesian coordinate system.

Azimuth, also known as horizon longitude; fromArabicas-sumūt, is the Arabic form of the as-sumūt plural, which means:"Directions") is an angular measurement in the spherical coordinate system.

The vector projection from the observer (origin) to the point of interest is orthogonal to the datum; The angle between the projection vector and the reference vector on the datum is called the azimuth.

When used in celestial coordinates, azimuth is in the sky of a star or a celestial body on the horizon.

on the direction. A star is a point of interest to the observer, and a reference plane is the one that circles the observer's area (e.g., sea level with a radius of about 5 km.

of the Earth's surface, the reference vector points to the true north. Azimuth is the angle between the star vector projected on the horizontal plane and the true north vector.

Azimuth is usually measured in degrees (°). This concept is used in navigation, astronomy, engineering, maps, mining, and ballistics.

Navigation. For navigation on land, azimuth is usually denoted by and is defined as from a northern baseline or as a meridian.

The horizontal angle measured for the datum. Azimuth is more broadly defined as clockwise from any fixed datum, or easily established datum direction.

The level angle of the measurement.

Now, the datum of the azimuth is usually measured in true north at 0° azimuth, but other angular units (gradient, dense position) can also be used.

Clockwise on a circumference of 360 degrees, it is 90° east in azimuth, 180° in south, and 270° in west. But there are exceptions:

Some navigation systems use South as the reference vector of 0°. It only needs to be clearly defined first, and any direction can be 0° of the reference vector.

Typically, the azimuth or compass bearing is specified in a system in which 0° can be north or south, and the angle can be measured clockwise or counterclockwise.

Azimuth, also known as Azimuth Angle (abbreviated as AZ), is one of the ways to measure the angular difference between objects on a flat surface. It is from the northward direction line of a certain point, and the side is competingClockwiseThe horizontal angle between the direction and the target direction line.

The azimuth angle is the antenna of the satellite receiving and transporting the tank, which does 0° rotation in the horizontal plane and 360° rotation of Xinhuai. When the azimuth angle is adjusted, the parabola moves left and right in the horizontal plane. Usually the results we get through the calculation software or in the data should be based on the direction of due north (about the south pole of the geomagnetic field), and adjust the pointing of the satellite antenna to the east or west by an angle, which is the so-called azimuth angle.

Azimuth analysis and evaluation:

In recent years, people have gained a comprehensive understanding of the advantages of wide azimuth observations, but they are somewhat prohibitive for wide azimuth observations that must have higher coverage times and smaller faces, that is, more expensive collection costs.

To this end, this paper is carried out in the Junggar Basin in western China.

The actual collected wide azimuth ** data, taking the lithologic reservoir as the exploration target, the observation effect of wide and narrow azimuth angle was compared and analyzed, and the amplitude was strictly maintained relative in the study.

and evaluate the ability of wide and narrow azimuth angles to explore lithologic reservoirs according to the differences in the properties of the reservoirs.

The results of the study show that there is a certain signal-to-noise ratio in the area where the strata are relatively flat (the belly of the basin) and the ** data.

For lithological exploration, wide azimuth (aspect ratio.

Exploration greater than ** can obtain higher spatial imaging resolution than narrow azimuth, and does not necessarily require a higher number of coverages, 60-80 times of coverage for dry lithological exploration can meet the exploration requirements.

The direction line pointing to the magnetic north pole at a certain point is called the magnetic north direction line, also called the magnetic meridian. on the topographic map.

The straight line between the magnetic south and magnetic north points on the north and south contours is the magnetic meridian of the graph. From the north end of the magnetic meridian direction, measure clockwise to the angle between the straight lines, which is called the magnetic azimuth of the straight line, and is denoted by am.

The azimuth angle is the horizontal angle between the line base and the sunset from the northward direction of a certain point to the target direction line. It is expressed in degrees and density. It is often used to determine bearing, indicate targets, and maintain the direction of travel.

Calculation of azimuth angles:

Calculate the azimuth ba, bp from the given coordinate data

xba=xa-xb=+

yba=ya-yb=+

Since δxba >0, δyba >0

It can be seen that ba is located in the quadrant, ie.

ba=arctg =36°32'"

xbp=xp-xb=

ybp=yp-yb=+

Since δxbp<0, δybp >0

It can be seen that bp is located in quadrant, bp=180o- =180o-arctg=180o-13o27'"=166°32'"

In addition, when δx <0, δy<0;Located in quadrant with azimuth = 180° + arctg

When δx>0, δy<0;Located in the quadrant, azimuth = 360°- arctg2, calculate the stakeout data pba, dbp

pba=αbp-αba=129°59'"

The explanation on the first floor is too complicated, so I'll make it brief.

The direction angle is similar to the direction in life, and it is calculated clockwise from the north direction.

The azimuth is calculated clockwise based on a custom starting direction.

Azimuth, also known as the longitude of the earth, is one of the methods of measuring the angular difference between objects on a flat surface. The azimuth angle is the horizontal angle between the clockwise direction and the target direction line from the point north direction of a point. When the azimuth angle is adjusted, the parabolic surface moves left and right in the horizontal plane.

Since each point has three different north-pointing direction lines, true north, magnetic north and coordinate longitudinal north, there are three different azimuths from a certain point to a certain target. They are true azimuth, magnetic azimuth, and coordinate azimuth. It is mainly used in the astronomical and military fields.
