Swarm's absolute magnetometer experimental vector mode, an innovative capability for space magnetometry [PDF]

open access: yesGeophysical Research Letters, 2015
AbstractEuropean Space Agency's Swarm satellites carry a new generation of 4He absolute magnetometers (ASM), designed by CEA‐Léti and developed in partnership with Centre National d'Études Spatiales. These instruments are the first ever spaceborne magnetometers to use a common sensor to simultaneously deliver 1 Hz independent absolute scalar and vector

In situ magnetometry study on the origin of anomalously capacity in transition metal sulfides

open access: yesChemPhysMater, 2023
Cobalt sulfides are considered as promising candidates for lithium-ion battery (LIB) anode materials with high energy densities. Their energy storage mechanism is widely understood to involve the traditional intercalation and conversion reaction. However,

Using distributed magnetometry in navigation of heavy launchers and space vehicles [PDF]

open access: yesProgress in Flight Dynamics, Guidance, Navigation, Control, Fault Detection, and Avionics, 2013
Recently, a new technique (magneto-inertial navigation, MINAV) has emerged to address the general problem of reconstructing the inertial velocity of a rigid body moving in a magnetically disturbed region. The contribution of this paper is to apply the developed method, in a prospective spirit, to a case of space navigation in view of estimating the ...

Ultimate limits for quantum magnetometry via time-continuous measurements [PDF]

open access: yes, 2017
We address the estimation of the magnetic field B acting on an ensemble of atoms with total spin J subjected to collective transverse noise. By preparing an initial spin coherent state, for any measurement performed after the evolution, the mean-square ...
