Simulation modeling

Definition

Simulation modeling is a computational technique that uses mathematical formulas and algorithms to replicate real-world processes, allowing for the analysis and prediction of complex systems' behavior over time. This approach is especially valuable in mission design and orbital considerations, as it enables engineers and scientists to visualize how spacecraft will navigate through space, account for various forces acting on them, and optimize trajectories for successful missions.
