The goal of this thesis is to develop an application for simulating satellite movement in space using orbital mechanics. The theoretical part will discuss existing satellite simulations and orbital dynamics. The implementation will use Unity to create a physics-based orbit simulation that integrates external forces like atmospheric drag and parses Two-Line Element (TLE) data for orbital parameters. Specialized libraries can be used to integrate both the simulation and TLE processing. The simulation will include supporting visuals and allow configurable satellite properties such as its 3D model, mass, size, or thruster power by a text-based configuration file. The satellite controls will be implemented via a generic control interface to allow multiple control schemas. The simulation will support multiple cameras that follow the satellite and periodically save images as output. Lastly, the implementation must be extensible as it will be a prototype simulation for Zaitra organization AI training.
