Space Applications

Our research interests include space applications and we develop theory and algorithms for the followings:

Optimal control of low-thrust orbit transfer

  • A Nonlinear Algorithm for Tracking Interplanetary Low-Thrust Trajectories [2]

Satellite formation/attitude control

  • Attitude Control of a Spacecraft with Single Variable-speed Control Moment Gyroscope [1]

  • Fuel-optimal Satellite Formation Reconfiguration near Elliptic Orbits [4]

Maneuver detection and tracking algorithms for spacecraft for space situational awareness
