Even if a measurement data group is not a measurement data group that is obtained in a space where the magnitude of a vector physical quantity to be measured is uniform, an offset with high reliability is estimated. The reliability of the estimated offset ...

There are provided an azimuth measurement device and its method for realizing an update of an offset calculated from the data acquired by azimuth measurement. A geomagnetism output measured by a 3-axis magnetic sensor (10) is amplified by an amplification ...

An azimuth measuring device capable of calibrating a magnetic sensor without putting load on a user is provided. When a point having amplified output values Sx, Sy, Sz after a sensitivity correction as x, y, z components is arranged on an xyz coordinate sy...

The sensor has silicon substrate (1) whose both ends are supported by a support structure (2), and a weight (3) that is installed at center of silicon substrate through a projected portion (3a). The substrate has piezoresistances (R1- R4) formed with defor...
