A Novel Deep Learning Approach to 5G CSI/Geomagnetism/VIO Fused Indoor Localization [PDF]

open access: yesSensors, 2023
For positioning tasks of mobile robots in indoor environments, the emerging positioning technique based on visual inertial odometry (VIO) is heavily influenced by light and suffers from cumulative errors, which cannot meet the requirements of long-term ...

Super‐Intense Geomagnetic Storm on 10–11 May 2024: Possible Mechanisms and Impacts [PDF]

open access: yesSpace Weather
One of the most intense geomagnetic storms of recent times occurred on 10–11 May 2024. With a peak negative excursion of Sym‐H below −500 nT, this storm is the second largest of the space era.

Geomagnetic Virtual Observatories: monitoring geomagnetic secular variation with the Swarm satellites

open access: yesEarth, Planets and Space, 2021
We present geomagnetic main field and secular variation time series, at 300 equal-area distributed locations and at 490 km altitude, derived from magnetic field measurements collected by the three Swarm satellites.

Electrostatic Solitary Structures in Space Plasmas: Soliton Perspective

open access: yesPlasma, 2021
Occurrence of electrostatic solitary waves (ESWs) is ubiquitous in space plasmas, e.g., solar wind, Lunar wake and the planetary magnetospheres. Several theoretical models have been proposed to interpret the observed characteristics of the ESWs.

L-shell and energy dependence of magnetic mirror point of charged particles trapped in Earth’s magnetosphere

open access: yesEarth, Planets and Space, 2020
In the Earth’s inner magnetosphere, there exist regions like plasmasphere, ring current, and radiation belts, where the population of charged particles trapped along the magnetic field lines is more.

AE, D ST and their SuperMAG Counterparts : the effect of improved spatial resolution in geomagnetic indices [PDF]

open access: yes, 2020
For decades, geomagnetic indices have been used extensively to parameterize space weather events, as input to various models and as space weather specifications.

Geomagnetism

open access: yes, 2021
Geomagnetism deals with all aspects of the Earth's magnetic field, also called the geomagnetic field, that surrounds our habitat in the form of the magnetosphere. We cannot sense the geomagnetic field in any way, and instrumental measurements as continuous recordings or dedicated surveys are necessary to study it.

Occurrence characteristics of electromagnetic ion cyclotron waves at sub-auroral Antarctic station Maitri during solar cycle 24

open access: yesEarth, Planets and Space, 2020
We present a statistical study of electromagnetic ion cyclotron (EMIC) waves observed at Antarctic station (geographic $$70.7{^\circ }\,\hbox {S}$$ 70.7 ∘ S , $$11.8{^\circ }\,\hbox {E}$$ 11.8 ∘ E , $$L=5$$ L = 5 ) on quiet and disturbed days during 2011–

Occurrence of blanketing Es layer (Esb) over the equatorial region during the peculiar minimum of solar cycle 24 [PDF]

open access: yesAnnales Geophysicae, 2014
A thin and highly dense sporadic E layer, which can occasionally block the upper ionospheric layers, is called blanketing sporadic E (Esb). We present the statistical seasonal local time occurrence pattern of Esb at equatorial station Tirunelveli (8 ...
