| description | Korea Pathfinder Lunar Orbiter (KPLO), also known as Danuri, was successfully launched on 4 Aug. from Cape Canaveral
Space Force Station using a Space-X Falcon-9 rocket. Flight dynamics (FD) operational readiness was one of the critical parts
to be checked before the flight. To demonstrate FD software’s readiness and enhance the operator’s contingency response
capabilities, KPLO FD specialists planned, organized, and conducted four simulations and two rehearsals before the KPLO
launch. For the efficiency and integrity of FD simulation and rehearsal, different sets of blind test data were prepared,
including the simulated tracking measurements that incorporated dynamical model errors, maneuver execution errors, and
other errors associated with a tracking system. This paper presents the simulation and rehearsal results with lessons learned
for the KPLO FD operational readiness checkout. As a result, every functionality of FD operation systems is firmly secured
based on the operation procedure with an enhancement of contingency operational response capability. After conducting
several simulations and rehearsals, KPLO FD specialists were much more confident in the flight teams’ ability to overcome the
challenges in a realistic flight and FD software’s reliability in flying the KPLO. Moreover, the results of this work will provide
numerous insights to the FD experts willing to prepare deep space flight operations. |
