Abstract:
A magnetic type azimuth/position measurement device is disclosed, comprising: a plurality of coils driven by circuitry, the circuitry and coils configured to selectively generate a uniform magnetic field and an inclined magnetic field in a three-dimensional space; a uniaxial magnetic field sensor configured to measure a strength of a magnetic field formed by the plurality of coils driven by circuitry; and arithmetic operation circuitry configured to receive signals representative of the strength of the magnetic field from the uniaxial magnetic field sensor and calculate a position and an azimuth of the uniaxial magnetic field sensor in the three-dimensional space.
