Research on astrodynamics, which designs the trajectories of spacecraft.
AboutAbout the lab
Designing spacecraft trajectories from the dynamics.
Assistant Professor Naoki Hiraiwa studies methods for designing spacecraft trajectories.
The research keywords are stochastic control, astrodynamics, trajectory design, orbital mechanics, and aerospace engineering.
Paper titles include travel in the space around the Earth and the Moon, designs for transferring between orbits in the shortest time with low thrust, and the design of orbits that wait for a comet.
Assistant Professor Hiraiwa belongs to the Artificial Environment and Information Division of the Faculty of Environment and Information Sciences, and also holds concurrent positions in the Department of Artificial Environment of the Graduate School of Environment and Information Sciences and in the Faculty of Engineering Science.
Key terms
- Astrodynamics
- The field that studies the motion of spacecraft using dynamics. It is used for trajectory design and control.
- Stochastic control
- An approach that represents uncertainty with probabilities and builds it into the control of motion.
- Low thrust
- Moving a spacecraft with a small thrust. It is one of the conditions in transfers between orbits.
ResearchResearch themes
The lab studies methods for designing spacecraft trajectories, using keywords such as orbital mechanics and stochastic control. Paper titles include travel in the space around the Earth and the Moon, transfers between orbits with low thrust, and the design of orbits that wait for a comet.
