Abstract:   The successful application of satellite navigation has a profound impact on the operational mode under the modern information-based condition. The information confrontation effect on the satellite navigation has great influence on the future war. Study on the scheme of GNSS navigation information confrontation and need to solve the key technical problems and the related technology test using satellite navigation signal simulator, GNSS receiver, integrated navigation equipment.Meaningful results are obtained, providing a reference for the navigation information Confrontation.
