Absolute Phase Bias

Definition

A stationkeeping algorithm concept for DRO formation flight: by controlling the deputy's crossing time of the selenocentric X-Z plane to lag behind the chief by a small time Δt, the deputy always maintains a safe distance behind the chief. This method is reference-trajectory-independent and directly controls the formation phase difference from the absolute motion perspective, with a slight advantage in safety.

Application Value

This concept is fundamental to cislunar orbital mechanics and mission analysis, providing essential theoretical support for trajectory design and operational planning.
