The new navigation method is put forward for the diversification of the navigation program. This is the radiation object map navigation based on the inverse passive location. The single observer depended navigation and multi observers corporative navigation are completed though the resolving inverse passive location equation after selecting the radiation objects with known position as the reference points. The basic principle, processing route, main characteristics and relative key technologies are discussed in detail. The application foreground is analyzed. It is the important reference for anti-jamming and anti-deceived diversity navigation.
