Phase Drift

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

A secular shift in the temporal location of a spacecraft along a libration point orbit relative to the baseline trajectory, arising because event-based targeting does not constrain the time component. If uncorrected, the accumulated drift degrades mission operations that depend on precise orbital phasing, such as eclipse avoidance.

Application Value

在相位漂移的设计与分析中，可用于优化转移方案，减少燃料消耗 为航天器的精确控制提供理论依据，确保任务执行的可靠性。
