Abstract

The layout problems of magnetometric gradiometer systems using three-component fluxgate transducers and three-component accelerometric transducers are considered. The transducers are also widely used in spatial orientation measuring systems. Basic mathematical models of three-component magnetometers included in the structure of the gradiometer and suitable for ideal location of a three-component transducer in the device case are proposed. The real layout of fluxgate meters in the gradiometer body is shown, and the angles of deviation of their sensitivity axes from the basis axes of the device are indicated. Refined mathematical models of three-component fluxgate transducers considering the angles of deviation of their sensitivity axes are presented. A method for calibrating a three-component magnetometer with mechanical rotations of fluxgate meters on verification devices and facilities (rotary tables), which allow one to set and control with high accuracy the required angles of the spatial orientation of the device case, is proposed. The errors of a three-component fluxgate transducer are measured using computational experiment (computer simulation).
