FIELD: physics.
SUBSTANCE: invention relates to devices for carrying out vector measurements of weak geomagnetic fields. One-component geomagnetic field sensor contains three parallel-positioned steel plates, in the gaps between which permanent magnets are installed, the like poles of which are attached to both sides of the inner plate, each generator is mounted on a dielectric substrate with a metallized base, the generators are placed in the gaps of the magnetization system between the magnets and are attached by a metallized base to opposite sides of the inner steel plate, the films of YIG resonators are made in the form of a square or a disk, the input and output converters of ultra-high frequency signals are located on opposite sides of the resonators and are oriented along the orthogonal axes of the resonators.
EFFECT: increased thermodynamic stability with rapid changes in ambient temperature.
