The dIdD Suspended Magnetometer for accurately measuring the changing Declination and Inclination of the Earth’s Field<\/span><\/h3>\n

In the past, magnetic observatories relied on a combination of Overhauser, fluxgate and theodolite instruments for obtaining measurements. GEM then introduced the dIdD (delta Inclination\/delta Declination) system for high precision results. \u00a0Next, dIdD was \u00a0enhanced significantly with the development of the Suspended dIdD system.<\/p>\n

Declination & Inclination Vector Magnetometer<\/h3>\n

GEM Systems latest development in this field is the Absolute Magnetic Declination & Inclination\u00a0(DI)\u00a0Meter. This instrument is being designed to provide a measurement of Declination and inclination at a given location on the globe. This system is an adaptation of the\u00a0dIdD vector magnetometer, this system will eliminate the need for a theodolite, by determining declination and inclination (not just changes in inclination \/ declination).<\/p>\n

GEM’s declination-inclination instrument is an Overhauser magnetometer with 2 sets of bias coils (horizontal & vertical) in the magnetic north plane.<\/p>\n

The new instrument (DI) simplifies setting observatory magnetometers by eliminating the need for fluxgate magnetometers and thermal insulating structures as before, and now a theodolite system.<\/p>\n

Observatory Applications<\/h3>\n

As described by the Israeli Nuclear group, Soreq, the dIdD is a vector magnetometer offering monitoring of the inclination and declination as well as total intensity of the earth’s magnetic field. Resolution is 0.01 nT with a recording interval of 5 samples per second.<\/p>\n

The Suspended dIdD instrument provides key benefits;\u00a0<\/strong><\/p>\n
