Definition
A station-keeping strategy used by the ARTEMIS mission: applying control near the X-axis of the Earth-Moon synodic coordinate system, constraining the X-direction velocity to zero at X-axis crossing. Validated in Sun-Earth libration point missions, it uses differential correction or optimization to compute a single target parameter, but over-constraint may increase fuel consumption.
