Mathematical models and methods of navigation support and ballistic design of spacecraft flights



Abstract:

The implementation of complex domestic projects for near- and far-space research requires ensuring a high probability of success and minimizing miscalculations and errors. Numerical methods, algorithms, and software packages implementing them must be developed taking into account the development of domestic ground-based and onboard computing equipment. Before implementing any space project, it is necessary to conduct computational experiments using mathematical modeling methods to ensure reliable completion of the assigned tasks.

Numerical methods, algorithms, and a set of onboard programs for the spacecraft’s autonomous navigation system have been developed, allowing for the determination of the spacecraft’s orbit based on a small number of visible navigation satellites. A set of onboard programs for controlling the spacecraft’s movement during its landing on the lunar surface has been created. Mathematical modeling of the spacecraft’s onboard navigation and control systems during its landing on the lunar surface has been performed. The task of designing spacecraft missions in the Solar System based on statistical modeling of flight trajectories between celestial bodies has been solved.
