A software-centric on-board navigation and trajectory-control framework is presented, integrating satellite positioning, inertial sensing, Kalman filtering, and aerodynamic surface actuation within a modular architecture. A ground control station with an interactive interface (PyQt5) supports real-time monitoring, parameter tuning, and trajectory replanning. In hardware-in-the-loop simulations and bench tests, the system maintains stable performance during short GNSS interruptions (up to 5 s) and reduces dispersion (CEP proxy) from 30-40 m to 3-10 m on a legacy unguided platform surrogate under representative wind disturbances. Open architecture facilitates scalability, reproducibility, and non-weaponized research use in aerospace navigation and control.
