As the role of satellite navigation systems in war continues to improve， it faces an increasingly complex battlefield electromagnetic environment， in order to ensure accurate and efficient transmission of timing and positioning information， and seize the information advantage， the military powers in the world continue to research and develop navigation war-related technology and its equipment， and its successful application to the construction of a new type of satellite navigation system and navigation jamming equipment， to improve the battlefield survivability of satellite navigation systems and the battlefield denial capability of navigation jamming equipment. The navigational warfare related overview and status role are introduced， the capacity status and development trend of navigational war are analyzed in detail， and the suggestions for the development of navigation warfare are given， the relevant research achievements can provide reference for the navigation development.
