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 …

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 …
