Definition

A stationkeeping algorithm concept for DRO formation flight: based on the target-point approach, correction impulses are applied at perilune. Using the state transition matrix to predict relative position deviation at the next target point, velocity increments are computed by solving linear equations to make the deputy strictly return to the reference trajectory at the target point. This method does not require real-time chief state information and has a slight advantage in reference trajectory tracking accuracy.

Application Value

This term has application value in the design and analysis of cislunar space missions, supporting trajectory design, mission planning, and system optimization. Researchers can analyze its physical mechanisms and engineering applicability based on specific mission requirements to advance cislunar space exploration technology.
