Spacecraft Trajectory Optimization Suite: Fly-Bys with Impulsive Thrust Engines (Stops-Flite)
<p>Spacecraft trajectory optimization is a near-infinite problem space with a wide variety of models and optimizers. As trajectory complexity increases, so too must the capabilities of modern optimizers. Common objective cost functions for these optimizers include the propellant utilized by the …

Spacecraft Trajectory Optimization Suite (STOpS): Optimization of Multiple Gravity Assist Spacecraft Trajectories Using Modern Optimization Techniques
<p>In trajectory optimization, a common objective is to minimize propellant mass via multiple gravity assist maneuvers (MGAs). Some computer programs have been developed to analyze MGA trajectories. One of these programs, Parallel Global Multiobjective Optimization (PaGMO), uses an interesting …

Orbital Optimization of Interplanetary Trajectories with Environmental Perturbations
<p>For a detailed analysis of orbital optimization, it is desired to incorporate a spacecraft environment model in order to have maximum confidence that the analysis will produce an accurate trajectory. Such a model requires the addition of orbital perturbations, or small forces acting on the …

Automated global optimization of low-energy trajectories using a hybrid optimal control framework
… and if successful, it generates a single trajectory of interest. A change in initial conditions or spacecraft parameters would require repeating the entire process. Multi-phase trajectories are defined for this study as trajectories that have multiple arcs that require propulsive maneuvers …
