A self-oscillating magnetometer based on nonlinear magneto-optical rotation using amplitude-modulated pump light and unmodulated probe light (AM-NMOR) in Rb has been constructed and tested towards a goal of airborne detection of 87 magnetic anomalies. In AM-NMOR, stroboscopic optical pumping via amplitude modulation of the pump beam creates alignment of the ground electronic state of the rubidi...

— This paper describes IMU (Inertial Measurement Unit) platforms and their main target applications with a special focus on the 10 degrees of freedom (10-DOF) inertial platform iNEMO™, its technical features and performances. The iNEMO™ module is equipped with a 3-axis MEMS accelerometer, a 3-axis MEMS gyroscope, a 3-axis MEMS magnetometer, a pressure sensor and a temperature sensor. Furthermor...

A new class of tri-axial miniature magnetometer consisting of a planar fluxgate structure with an orthogonal ferromagnetic fluxguide centrally situated over the magnetic cores is presented. The magnetic sensor possesses a cruciform ferromagnetic core placed diagonally upon the square excitation coil under which two pairs of pick-up coils for in-plane field detection are allocated. Effective pri...

Abstract With the accumulation of data, it is possible to study long-term variation Fluxgate Magnetometers (FGM) High Precision Magnetometer (HPM) onboard China Seismo-Electromagnetic Satellite (CSES). The calibration method HPM depends on an assumption that linear parameters FGM, including gain factors, offsets, and non-orthogonal angles are stable. However, exhibits some unexpected trends in ...

A complete vector-2D micro-integrated sensors system for magnetic field measurement is proposed. The system consists of a micro-integrated Fluxgate magnetometer with front-end electronic circuitry based on second-harmonic detection. The magnetic core of the sensor is the VITROVAC 6025X deposited over the micro-integrated coils with the RF magnetron sputtering process deposition.

In most field environments, unexploded ordnance (UXO) items are found among extensive surface and subsurface clutter and shrapnel from ordnance. Traditional algorithms for UXO remediation experience severe difficulty distinguishing buried targets from anthropic clutter. Furthermore, naturally occurring magnetic geologic noise often adds to the complexity of the discrimination task. These proble...

The standard observatory procedure for determining a geomagnetic field’s declination and inclination absolutely is the DI-flux measurement. The instrument consists of a non-magnetic theodolite equipped with a single-axis fluxgate magnetometer. Additionally, a scalar magnetometer is needed to provide all three components of the field. Using only 12 measurement steps, all systematic errors can be...
