Base station magnetometers for ground mag surveys.

While any kind of magnetometer can be used as a base station magnetometer to record temporal variations in the geomagnetic field, some are more accurate and convenient than others. It is convenient to use a base station from the same manufacturer since the software that comes free with those magnetometers can diurnally correct that data. […]

Geophysics heading corrections

Normally the only data correction applied to ground magnetic data is a diurnal (a.k.a base station) correction. This type of correction simply subtracts the static base station reading from the moving rover magnetometer reading of the same time. Cs vapour sensors also require a geophysics heading correction to account for the changes in magnetic field […]
