To improve the robustness and reliability of satellite navigation system, it is necessary to design and implement robust spatio-temporal anti-interference algorithms. This paper aims to study the robust spatio-temporal anti-interference algorithm and hardware implementation of satellite navigation system. Firstly, the composition and working principle of satellite navigation system, as well as existing anti-interference algorithms are introduced. Then, a robust spatio-temporal anti-interference algorithm based on time-frequency information fusion is designed and implemented to verify its performance. Finally, the algorithm is hardware-implemented, including selecting appropriate hardware platforms, designing hardware modules, optimizing algorithm and hardware interfaces, etc. Through experiments, the designed and implemented algorithm and hardware system can effectively resist various interferences, ensuring positioning accuracy and system reliability.
