In order to make weapons much more effective in hostile environments, new developments in embedded GNSS/INS integration architectures which offer the possibility of substantial improvements in jamming immunity have aroused great attention from the researchers. This paper introduced the principle and construct of embedded GNSS/MIMU integrated navigation receiver, and presented the method of using MIMU to aid GNSS receiver tracking loop. This technique improved the accuracy of the estimated Doppler frequency, which resulted in higher dynamic and anti-jamming performance. Finally, the paper analyzed anti-jamming performance of embedded GNSS/MIMU integrated navigation receiver. According to the sample of GPS/MIMU, the simulation was done. The simulation results show that anti-jamming performance of embedded GNSS/MIMU integrated navigation receiver has 11dB improvement in comparison with the traditional GNSS receiver.
