GEOMAGNETIC MEASUREMENTS IN LATVIA

open access: yesGeodesy 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 vary over time.

Manifestations of Strong IMF‐By on the Equatorial Ionospheric Electrodynamics During 10 May 2024 Geomagnetic Storm

open access: yesGeophysical Research Letters
Understanding the effects of east‐west component of interplanetary magnetic field (IMF‐By) on the equatorial ionospheric electrodynamics is challenging due to the complex response caused by the simultaneous occurrence of multiple mechanisms during ...

Fixed point observation of geomagnetism for dynamic fingerprinting map construction [PDF]

open access: yes, 2018
Fingerprinting requires sensor data map to estimate a user’s location by comparing the map with sensor data of the user’s device. Although it is assumed that the sensor data does not change, it is considered that the premise is not stable in the ...
