Tokumoto, T. & Owada, T.
Abstract
We investigated a new method of making absolute geomagnetic measurements with a device composed of (1) three orthogonal coils to produce an artificial compensating magnetic field, (2) a geomagnetic total force magnetometer installed in the center, (3) a set of tilt meters, and (4) an azimuth mark. Magnetic declination can be measured by using the azimuth mark to determine the precise direction of the artificial magnetic field generated by the compensating coils. We show two measurement methods of (1) magnetic declination only and (2) all three vector components of the geomagnetic field.
