Which Digital-Output MEMS Magnetometer Meets the Requirements of Modern Road Traffic Survey?

open access: yesSensors, 2021
Present systems for road traffic surveillance largely utilize MEMS magnetometers for the purpose of vehicle detection and classification. Magnetoresistive sensing or LR oscillation circuitry are technologies providing the sensors with the competitive ...

Mars Orbiter magnetometer of China’s First Mars Mission Tianwen-1

open access: yesEarth and Planetary Physics, 2020
As one of the seven scientific payloads on board the Tianwen-1 orbiter, the Mars Orbiter Magnetometer (MOMAG) will measure the magnetic fields of and surrounding Mars to study its space environment and the interaction with the solar wind.

Magnetometers for tracking metallic targets [PDF]

open access: yes2010 13th International Conference on Information Fusion, 2010
Starting from Maxwell's equations, we derive a sensor model for three-axis magnetometers suitable for localization and tracking applications. The model depends on the relative position between the sensor and the target, and a physical magnetic multipole model of the target.

NMR Detection with an Atomic Magnetometer [PDF]

open access: yesPhysical Review Letters, 2005
We demonstrate detection of NMR signals using a non-cryogenic atomic magnetometer and describe several novel applications of this technique. A water free induction decay (FID) signal in a 0.5 $μ$T field is detected using a spin-exchange-relaxation-free K magnetometer and the possibility of using a multi-channel magnetometer for 3-D MRI requiring only a

Nuclear quantum-assisted magnetometer [PDF]

open access: yesReview of Scientific Instruments, 2017
Magnetic sensing and imaging instruments are important tools in biological and material sciences. There is an increasing demand for attaining higher sensitivity and spatial resolution, with implementations using a single qubit offering potential improvements in both directions.

Long‐Term Bias Stability of the GOES‐NOP Magnetometers

open access: yesEarth and Space Science, 2023
We characterize the long‐term bias stability of the GOES‐NOP series magnetometers (GOES‐13, 14, and 15) using data from 2013 through 2018. Bias stability is inferred using three methods: comparing the inboard and outboard measurements on each spacecraft,

Magnetic Field Signatures of Tropospheric and Thermospheric Lamb Modes Triggered by the 15 January 2022 Tonga Volcanic Eruption

open access: yesGeophysical Research Letters, 2023
Intense eruptions of the Tonga volcano activated prominent traveling atmospheric disturbances (TADs) at 04:05UT on 15 January 2022. Himawari‐8 satellite images depict that TADs of the tropospheric Lamb wavefront propagate with a speed of 315 m/s and ...

Stronger Evidence of a Subsurface Ocean Within Callisto From a Multifrequency Investigation of Its Induced Magnetic Field

open access: yesAGU Advances
The magnetometer investigation of the Galileo mission used the phenomenon of magnetic induction to produce the most compelling evidence that subsurface oceans exist within our solar system. Although there is high certainty that the induced field measured

I-DWRL: Improved Dual Wireless Radio Localization Using Magnetometer

open access: yesSensors, 2017
In the dual wireless radio localization (DWRL) technique each sensor node is equipped with two ultra-wide band (UWB) radios; the distance between the two radios is a few tens of centimeters.
