OTIS: Optimal Trajectories by Implicit Simulation OTIS is a general purpose trajectory optimization program. It can and has been used to support analysis for a variety of vehicles and missions, including aircraft, spacrcraft and launch vehicles. The generality of OTIS4 allows users to define their own variables, objective function, and constraints, and equations of motion. OTIS4 is also capable of optimizing the trajectories of underwater autonomous vehicles and classic control problems such as the brachistochrone and supersonic aircraft minimum-time-climb.
