摘要

Global positioning satellite/inertial navigation system (GPS/INS) integrated navigation systems are widely used for many military applications due to their complementary features. It is normally assumed that the military GPS receiver will be used in a signal-jamming environment. Various anti-jamming techniques have been studied from the point of hardware and/or software. The velocity aiding method is a well-known software-based anti-jamming technique used for GPS/INS integrated navigation systems. The dynamics of the GPS receiver can be measured by an INS and then fed into tracking loops to reduce the tracking loop bandwidth to promote jamming resistance. The Korean government has been developing a GPS adapter kit (GAK) that can change a conventional bomb into a high-precision GPS guided bomb (GGB). In this paper, we introduce a GPS/INS integrated navigation system in a GAK, a velocity aiding method applied to the navigation system, anti-jamming test procedures and the results for a GGB. The test results show that the GPS/INS integrated navigation system using velocity aiding method can provide enhanced anti-jamming capability by efficiently reducing the tracking loop bandwidth.
