Phase Deviation

Definition
Position deviation of a spacecraft along the orbital direction relative to the reference trajectory on a periodic orbit. In cislunar libration point orbit station-keeping, single-maneuver control methods (e.g., XAC) can assign at most three of six translational state components per maneuver, causing the spacecraft's xz-plane crossing time to diverge from the baseline. The along-track position drifts ahead or behind, accumulating over time to the order of days.
Application Value
This concept is applicable in cislunar space mission design, orbit optimization, and trajectory planning for spacecraft transfers and maneuver strategies.
