High-Precision Magnetic Testbed Design and Simulation for LEO Small-Satellite Control Test

Aerospace, 2023
Small satellites with academic missions in low Earth orbit (LEO) employ magnetic attitude control systems primarily due to their ease of development and low cost. These systems utilize magnetorquers to generate a magnetic moment that interacts with Earth’

Can core-surface flow models be used to improve the forecast of the Earth's main magnetic field? [PDF]

, 2008
[1] Geomagnetic main field models used for navigation are updated every 5 years and contain a forecast of the geomagnetic secular variation for the upcoming epoch. Forecasting secular variation is a difficult task.

Geomagnetic measurements in Latvia

Geodesy and Cartography, 2012
The knowledge of the Earth's magnetic field elements and their dynamic fluctuations over the area concerned are important and can be used for many practical purposes in various fields, including Geodesy and Cartography. Earth's magnetic field tends to

Is the Earth’s Magnetic Field a Constant? A Legacy of Poisson

Geosciences, 2023
In the report he submitted to the Académie des Sciences, Poisson imagined a set of concentric spheres at the origin of Earth’s magnetic field. It may come as a surprise to many that Poisson as well as Gauss both considered the magnetic field to be ...

Generation of By in Earth’s magnetotail with the effect of IMF By during southward interplanetary magnetic field

AIP Advances, 2021
Based on the three-dimensional compressible resistive MHD models, the Earth’s dipole magnetic field is employed to investigate IMF By penetration driven by the solar wind during southward interplanetary magnetic field (IMF) with uniform resistivity.

Calculation of the power and angular components of the geomagnetic field induction vector in the territory of Ukraine

Геофизический журнал
The study calculates the geomagnetic field induction vector power and its angular components for the territory of Ukraine for the 2024.5 epoch. We used a digital map of the ∆Bа induction module anomalies and B0, the Earth’s normal magnetic field.

Search for energetic cosmic axions utilizing terrestrial/celestial magnetic fields [PDF]

, 1998
Orbiting $\gamma$-detectors combined with the magnetic field of the Earth or the Sun can work parasitically as cosmic axion telescopes. The relatively short field lengths allow the axion-to-photon conversion to be coherent for $m_{axion} \sim 10^{-4}$ eV,
