Definition
An orbital control strategy to maintain a spacecraft near a target position. The paper adapts GEO satellite positioning techniques, combining east-west control (cross-track thrust for semi-major axis correction) and north-south control (normal thrust for inclination correction) to keep the spacecraft near the triangular libration point.
Application Value
Position-Keeping plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
