A gimbal is a two or more axis mount.
The configuration may be altitude over azimuth (Alt-Az), altitude over altitude (Alt-Alt), equatorial,
or a combination of the above.
The Optical Configurations Summary table
identifies the typical uses for each configuration.
Examining the three configurations leads to the conclusion that they are really the same.
Only the orientation of the gimbal referred to the fixed mounting surface (typically the earth's surface)
DFM Engineering has built all of the axes configurations of gimbals.
