What is azimuth? What is polarization angle?

the azimuth (azimuth) is calculated from the northbound line of a certain point, and the horizontal included angle between the directional lines clockwise to a certain target point is called the azimuth of the target point. It is called "true azimuth" from the true meridian; It is called "magnetic azimuth" from magnetic meridian; It is called "coordinate azimuth" from the vertical line in the coordinate system. Its angle value is between and 36.

the angle on the horizon, measured from due east to the north, until it passes through the angle at which the meridian of the measured celestial body intersects with the horizon.

Aspect Angle(AA): azimuth, indicating the angle of our plane relative to the axis of the enemy plane. Different from "attack angle". Directly behind the enemy plane (at 6 o'clock) is degrees, and at the opposite position (at 12 o'clock) is 18 degrees.

polarization angle is the angle that the tuner rotates relative to the standard position (for the C-head, the scale of is generally at four points, and the positions of different manufacturers may be different, and the ku-head, the scale of , or the arrow points directly above), which is positive clockwise and negative counterclockwise. Theoretically, the polarization angle is positive for all satellites due south to east, and negative for satellites due west.
