The integrated navigation technique is the hotspot in the domain of navigation technique at present and also is the development trend of the combinated navigation technique. By analyzing the development trend of armored platform and summarizing the overseas technique route, the paper provides the idea of designing integrated navigation system for armored vehicles, expounds the function and characteristic of the system, presents a project of integrated navigation system based on these navigation sensors as inertial navigation, satellite navigation, milemeter, altimeter and attitude sensor etc, analyzes and explains the involved key technique. A series of problem needed to be solved is presented in paper by analyzing the integrated navigation system for armored vehicles.
