Open space trajectory optimizer

WebVersatile ImpulSive Interplanetary Trajectory OptimizeR (VISITOR) (LAR-18538-1) Overview The design of trajectories for interplanetary missions represents one of the most complex and important problems to solve during conceptual space mission design. WebIf an open-loop control is desired, the multiple solutions resulting from the inverse prediction queries are used to plan a trajectory in the joint space, as described with more detail in Section IV. This results in a general, learning based control scheme that can be switched from closed to open-loop at an y time, either due to a high
