Proton magnetometer sensor design and its performance

Design and performance of an absolute He/Cs magnetometer

We report on the design and performance of a highly sensitive combined He/Cs magnetometer for the absolute measurement of magnetic fields. The magnetometer relies on the magnetometric detection of the free spin precession of nuclear spin polarized He gas by optically pumped cesium magnetometers. We plan to deploy this type of combined magnetometer in an experiment searching for a permanent elec...

Static and Dynamic Attitude Decomposition for Estimation with Magnetometer Sensor

A priori information given by the complete modelling of the ballistic behavior of a projectile is simplified to give a pertinent reduced evolution model. This model is composed of quasi-static and dynamic models. An extended Kalman filter is designed to estimate dynamic part of the 3 attitude angles (roll in [0, 2π], angle of attack and side-slip in the range of few milliradians) from measures ...

Design of Smart Magnetometer as Sensor Node for Seafloor Geomagnetic Observatory

Seafloor observatories have been the important way to observe the ocean, but applying the magnetometers to it still remain technical problems. This paper presents a smart cheaper magnetometer which was designed as the sensor node for a small seafloor network for geomagnetic observation. System design was described in modules at first. The calibration method of the whole system so as to alleviat...

Design and Analyses of a MEMS Based Resonant Magnetometer

A novel design of a MEMS torsional resonant magnetometer based on Lorentz force is presented and fabricated. The magnetometer consists of a silicon resonator, torsional beam, excitation coil, capacitance plates and glass substrate. Working in a resonant condition, the sensor's vibration amplitude is converted into the sensing capacitance change, which reflects the outside magnetic flux-density....
