Definition

The maximum value of the DRO's position component in the z-direction (perpendicular to the Earth-Moon orbital plane). A larger amplitude yields higher visibility elevation angles for lunar polar regions and stronger constellation coverage of high-latitude areas.

Application Value

z-direction Motion Amplitude is an important orbit type in cislunar trajectory design, widely applied in mission planning.
