Abstract:This article uses the Newton iteration method to quickly optimize the launch azimuth angle, overcoming the defect of excessive initial deviation of the launch azimuth angle, and greatly shortening the optimization time. By adopting feature parameter grid-based program angle optimization design technology, a program angle design parameter database has been established, which can quickly perform parameter interpolation in the case of maneuvering launch, avoiding a large amount of optimization calculation process, and effectively supporting the rapid generation of launch orbit in the case of maneuvering launch. Finally, the effectiveness and correctness of the designed algorithm are demonstrated through simulation.
