Abstract:	In order to reduce the dependence of pedestrian navigation on satellite navigation system and wireless communication, a method is studied to construct pedestrian navigation system based on micro inertial technology. In the study, the distributed system structure is arranged on human feet, legs and trunk, and the key technologies, including virtual inertial sensor, initial alignment and error correction, precise gait-phase detection, effect and inhibition of environmental magnetic field are researched. A detailed analysis of the performance characteristics of the pedestrian navigation system is carried out in the environment of electromagnetic interference. Experimental results show that, the positioning error of route with electromagnetic interference accounts for 2.5% of the walking distance. The key technologies proposed in the study can effectively improve the positioning accuracy of pedestrian navigation system, and independently achieve longer time personal navigation in the GNSS and Wireless communication attenuation or invalid environment.
