Lunar Occultation Avoidance

Author: Tianjiang Shuo

Definition

A constraint in libration point orbit design that prevents the Moon from blocking the line of communication between the spacecraft and Earth. When selecting halo or Lissajous orbits near the Earth-Moon L2 point, the full arc must be free of lunar occultation of the Earth communication link, directly affecting the choice of orbit amplitude and configuration.

Application Value

This constraint ensures full-arc visibility of Earth communication links in L2 orbit design, directly affecting orbit amplitude and configuration selection.
