Enhanced PNT (Positioning, Navigation and Timing) equipment is critical in modern military operations. Its highly accurate time and position reference provides the basis for precision strikes and ensures cross-service and cross-domain operational synergy and unity. Through multi-source fusion and encryption, the enhanced PNT can maintain reliability in a confrontational environment and assist the command system in real-time situational awareness and scientific decision-making. At the same time, it supports the autonomous operation of unmanned platforms, strengthens the concept of distributed warfare and provides a solid data base for logistics support and infrastructure operation. All in all, the enhanced PNT builds a solid space-time support for modern warfare and significantly improves combat effectiveness and flexibility.
