Overview of the Flight Dynamics Subsystem for Korea Pathfinder Lunar Orbiter Mission

Korea’s first lunar mission, the Korea Pathfinder Lunar Orbiter (KPLO), aims to launch in mid-2022 via Space-X Falcon-9 vehicle. For successful flight operation of KPLO, Aerospace Research Institute (KARI) has designed and developed Flight Dynamics Subsystem (FDS). FDS is one subsystems KPLO Deep-Space Ground System (KDGS), which responsible for overall dynamics-related operation. currently successfully implemented meets all requirements derived from critical design phases. The current work addresses implementation results FDS. Starting overviews on payloads, bus systems, mission trajectory characteristics, a review KDGS also treated briefly. Details philosophy, unique functionalities six different modules nested inside with its Graphical User Interface (GUI) are discussed. Moreover, efforts devoted preparation summarized, including many collaborative works between KARI National Aeronautics Space Administration (NASA) teams.
