In recent years, global navigation satellite systems (GNSSs) play an increasingly important role in all aspects of life, especially in the field of national defense and security. However, due to weak signal characteristics and simple data structure, satellite navigation signals are prone to attenuation, interference, and even spoofing attacks, making the application of satellite navigation in particular environments such as defense-security become less effective. Therefore, the research and development of a ground-based navigation system capable of operating completely independent of satellite navigation systems is essential to overcome the above disadvantages. Such system is aimed to locate and guide vehicles, equipment and weapons in military operations in proximate regions. In this paper, we propose to build a ground navigation system with a time synchronization mechanism between transmitters and receivers similar to existing Locata system. Simulation results for a limited scenario show that local positioning is completely feasible and can be developed for a real-life system.
