Abstract

Abstract: The method of seamless combination of IMU and GPS module based on Android mobile terminal is researched and implemented, and the design scheme and experimental results are given. When the GPS signal is missing, the gait detection, heading calculation and track estimation can be carried out by using the IMU inertial sensor which is inherent in the mobile terminal to complete the seamless positioning. Based on the Android system and the open platform of Baidu map, the algorithm implementation and human-computer interaction can be completed in the mobile terminal. The test results show that the relative error of the system location can be controlled within 5 meters by the single IMU positioning scheme in the absence of GPS signal, which can meet the navigation and positioning requirements in the general indoor environment.
