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.
The point from where an azimuth originates is the center of an imaginary circle.
nothing =)
Azimuth is the angular position of any place with respect to North, measured clockwise.
aha
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.

An azimuth thruster is an engine and ship's propeller in a pod which is azimuth adjustable.
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.

Azimuth Systems was created in 2002.
RBG-Azimuth was created in 2006.
Collimation is used for telescopes to make sure the telescopes are perfectly aligned. The reflector will not produce the best image if the aligned is not just right.
Collimation Error: Collimation error occurs when the collimation axis is not truly horizontal when the instrument is level. The effect is illustrated in the sketch below, where the collimation axis is tilted with respect to the horizontal by an angle α: Figure ( ) In this particular example, the effect is to read too high on the staff. For a typical collimation error of 20", over a sight length of 50m the effect is 5mm. If the sight lengths for back sight and foresight are equal, the linear effect is the same for both readings. When the height difference is calculated, this effect cancels: δh = (b + s. α) - (f + s. α) = b - f That is, the effect of the collimation error is eliminated if sight lengths are kept equal.
Azimuth - album - was created in 1977-03.
