Where is due west?

Due west is the west, 9 o'clock is due west.

Azimuth, also called Azimuth (Az), is one of the methods to measure the angle difference between objects on a plane. It is the horizontal angle clockwise from the northbound line of a certain point to the target line.

The azimuth angle of the satellite receiving antenna rotates 0-360 degrees on the horizontal plane. During azimuth adjustment, the paraboloid moves left and right on the horizontal plane. Usually, the result we get from the calculation software or data should be to point the satellite antenna to the east or west at an angle based on the true north direction (about the geomagnetic south pole), which is called azimuth.

Ways to tell the direction in the field:

1, observing the leaves of trees, the lush side is the south, because the light is always in the south, so the branches in the south are dense. For a long time, trees will spread to the south.

2. Some natural villages are generally concentrated on the south side of the mountain, and most of the gates face south. Generally, ancient temples, pagodas, ancestral halls and other buildings face south.

If you can see the stars in the sky at night, you can find the bright Polaris along the extension line of the spoon handle as long as you find the Big Dipper, and the direction of Polaris is the true north direction.
