ENHANCED STATIONKEEPING MANEUVER CONTROL TECHNIQUE FOR DELTA-V COST REDUCTION IN THE KOREA PATHFINDER LUNAR ORBITER

This paper proposes an enhanced control technique for stationkeeping maneuvers to reduce Delta v costs for the Korea Pathfinder Lunar Orbiter (KPLO). A scheduled circularization control technique exploits patterns in the evolution of the line of apsides and eccentricity to achieve a significant reduction in station keeping Delta v costs based on spacecraft requirements. The technique is compared against previous algorithms implemented for maneuver operations of the Lunar Prospector and Lunar Reconnaissance Orbiter (LRO) missions in the USA and KAGUYA in Japan. Through Monte Carlo analysis, the efficacy and robustness of the proposed method are verified, and the technique is shown to meet the operational requirements of KPLO.
