Abstract: PURPOSE: A position estimation device and method using an acceleration sensor are provided to calculate gravity acceleration without a rotary motion component by using three shaft angular speed measured by a gyro sensor and three shaft acceleration measured by acceleration sensors. CONSTITUTION: First and second acceleration sensors measure three shaft acceleration. A gyro sensor measures three shaft angular speed of a position estimation device. A magnetic sensor detects an azimuth of the position estimation device. A sensor signal processor converts analog sensor signals to a sensor signal for digital calculation.
