This paper proposed the flight test methods of integrated navigation system for GPS guided bombs. The integrated navigation system consisted of an RF/IF process module including GPS receiver, an integrated navigation process module, and an Inertial Measurement Unit. In the development phase of guided bombs, flight test is very important means of test and evaluation for guided bombs. Especially, in order to evaluate navigation performance of GPS/INS integrated navigation system mounted in a GPS guided bomb, we definitely need the true flight path of guided bombs. It is possible to evaluate the navigation performance by comparing the output of integration navigation system with the DGPS reference trajectory. The DGPS reference trajectory was acquired by using the GPS raw measurement of navigation system which was transmitted via the telemetry system. We proposed the navigation performance evaluation system for GPS/INS Integrated Navigation Guided Bombs.
