The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere).
It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.

An azimuth circle is a device used for measuring azimuths, a graduated circle on a sight, gun carriage, searchlight, etc.
To calculate azimuth closure, first determine the azimuths for each leg of your traverse using the initial bearing and the angles turned at each station. Sum all the azimuths to find the total azimuth. The azimuth closure is then calculated by taking the difference between the sum of the azimuths and the azimuth of the starting point, adjusting for 360 degrees as necessary. A closure value close to zero indicates a well-closed traverse.
To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.
You would use a protractor or a compass to determine a grid azimuth on a map. These tools help you measure the angle between a grid line and the north direction on the map, providing the azimuth reading.

The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere). It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.
An azimuth is defined as a horizontal angle measured clockwise from a north base line. This north base line could be true north, magnetic north, or grid north. The azimuth is the most common military method to express direction. When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle . This circle is divided into 360 degrees or 6400 mils . NORTH IS 0/360 AZIMUTH EAST IS 90. SOUTH IS 180. WEST IS 270.
A BACK AZIMUTH IS A PROJECTION OF THE AZIMUTH FROM THE ORIGIN TO THE OPPOSITE SIDE OF THE AZIMUTH CIRCLE. i.e. THERE ARE 360 DEGREES IN AN AZIMUTH CIRCLE, THUS THE OPPOSITE DIRECTION IS 180 DEGREES.
An azimuth thruster is an engine and ship's propeller in a pod which is azimuth adjustable.
The point from where an azimuth originates is the center of an imaginary circle.
