Reasons and benefits of using JAXA Supercomputer System
Parallel computation is possible, thus reducing analysis time.
Achievements of the Year
Monte Carlo simulations of orbit planning and orbit determination operations during the spiral orbit raising phase of DESTINY+ are being conducted to evaluate the required ground station path assignment, ground station observation volume, IES outage period required for acquisition operations, and the consistency rate between long-term and short-term station adjustments, which will be reflected in the spacecraft operation design.
