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 DESTINYplus are being conducted to evaluate the required ground station path assignment, ground station observation volume, IES outage period required for acquisition operations, the consistency rate between long-term and short-term station adjustments, and optimization of parameters in orbit determination, which will be reflected in the spacecraft operation design.
Based on the above results, we plan to evaluate the effectiveness of the on-board trajectory propagation function, improve path assignment consistency, and evaluate the logic of Yaxis reversal control.
