PRELIMINARY TESTS FOR MEASURING F. H AND D COMPONENTS OF THE GEOMAGNETIC FIELD BY USING A PROTON PRECESSION MAGNETOMETER |

| Abstract: | In order to perform easily the automatic routine observation of three components of the geomagnetic field F. H and D by using a proton precession magnetometer some preliminary tests have been carried out. The measured base-line values o Type-57 magnetic variometer operating at Wuhan geomagnetic observatory are all very stable: H_B=34514.7±0.6~γ Z_B=34470.2+0.9~γ D_B=-3°25.15′+0.14′ IB=44°57.80′+0.06′ Furthermore, a possible and handy way for automating the routine observation of the magnetic field at the observatory with the aid of the proton precession magnetometer has also been disecused. |
