Figure 6 the test result schematic 5 EPILOGUE The article describes the hardware and software algorithms design of the pedestrian dead reckoning device based on the micro-controller STM32F103RBT6, which completes the multi-sensor data acquisition and dead reckoning. The system which uses micro inertial devices and the micro-controller can meet the applicable requirement of miniaturization, practicality and portability and has the ease of setting up a system.Field experiments prove that the measurement accuracy can meet the actual demand.
