Optimal Reconfiguration of Tetrahedral Formations

摘要

The problem of minimum-fuel formation reconfiguration for the Magnetospheric Multi- Scale (MMS) mission is studied. This reconfiguration trajectory optimization problem can be posed as B nonlinear optimal control problem. In this research, this optimal control problem is solved using a spectral collocation method called the Gauss pseudospectral method. The objective of this research is to provide highly accurate minimum-fuel solutions to the MMS formation reconfiguration problem and to gain insight into the underlying structure of fuel-optimal trajectories.
