What is true statement regarding Azimuth?

It is measured in hours

It is analogous to latitude

It is the angular distance measured from the East point of horizon

It is the angular distance measured from the North point of horizon

Correct Answer : It is the angular distance measured from the North point of horizon

Explanation : Azimuth is the second parameter of the Azimuth Elevation system & is defined as the angular distance measured from the North point of horizon in the horizontal direction. It is analogous to the longitude system of the Earth & is measured in degrees.

How many rotations are required to transform the ECI coordinate system to the perifocal system?

Correct Answer : Option (D) : 3

Explanation : The coordinate transformation from XYZ frame to X’Y’Z’ frame is carried out by a single rotation about one axis. The other two axes remain in the same plane. But to transform from the ECI coordinate system to the perifocal system, there have to be successive 3 rotations. The first rotation is about Z axis, second is through X’ axis and the final rotation is bout Z’’ axis.
