Continuous Low-Thrust Trajectory Optimization: Techniques and Applications
Trajectory optimization is a powerful technique to analyze mission feasibility during mission design. High-thrust trajectory optimization problems are typically formulated as discrete optimization problems and are numerically well-behaved. Low-thrust systems, on the other hand, operate for …

Automated planetary satellite tour planning with a novel low-thrust direct transcription method
… designers have started to consider the use of low-thrust electric propulsion systems on board the spacecraft to enable future tours. The optimal trajectory for a given mission profile using low-thrust may be highly non-intuitive. There are thus many challenging aspects to the design of multiple …

Robust preliminary design for multiple gravity assist spacecraft trajectories
The development of a new spacecraft trajectory design method most often occurs because a particular capability does not exist. The invention is usually considered successful so long as it is capable of producing solutions to the problem in question, and thus satisfies a particular design …
