GEOMAGNETIC INSTRUMENTATION FOR REPEAT STATION SURVEY
Repeat station survey measurements are important geomagnetic data because they are widely used both for fundamental science (e. g., study of Earth’s magnetic dynamo) and for applied purposes (e.g., declination charts for aviation safety). To execute repeat station surveys, normally three types of instruments are used: absolute scalar magnetometers, threecomponent vector variometers, and theodolite-mounted one-component magnetometers. The modern specifications of each magnetometer are described together with simplified fundamentals of their operation. The recommended set of such devices is given and possible further development of this type of instrumentation is discussed.
