DGPM is proposed to solve the positioning problems during the GPS outages. When the GPS signal is available, the integrated system works under GPS/INS loosely-coupled mode. And the DGPM stores the GPS position information. Once the GPS data fails, the well trained module will continuously provide pseudo-GPS position data to aid the pure INS. Field test data was collected to evaluate the performance of the DGPM. It can been seen that, during the 20 s GPS outages, the proposed DGPM is much better than the pure INS mode.
