A hybrid wavelet-wiener noise reduction algorithm for geomagnetic signals in dynamic positioning
Alexandria Engineering JournalIndoor positioning technology is a hotspot in current research, and geomagnetic combined positioning is one of the mainstream directions. Currently, indoor or underground positioning techniques are all passive positioning such as RFID, UWB, WIFI and ...

The evolution of electron density and temperature distributions in the topside ionosphere during magnetic storms [PDF]
The latitudinal distributions of electron density and temperature during geomagnetic storms in the mid-latitude topside ionosphere are observed to change in a manner than can be related to the evolution of ring current particle populations. The region of

Ionospheric Variations Associated, with Geomagnetic Disturbances
Journal of geomagnetism and geoelectricity, 1953 Variations in the densities and heights of the ionospheric Es and F2 regions during magnetic storms are studied. At the moderate latitudes in summer solstice and at the equatorial zone, the disturbance variation of the Es in both local time (SD) and storm time (Dst) is obtained by statistical examination, although the individual values of the Es data ...

Large-scale, near-Earth, magnetic fields from external sources and the corresponding induced internal field [PDF]
Data from MAGSAT analyzed as a function of the Dst index to determine the first degree/order spherical harmonic description of the near-Earth external field and its corresponding induced field. The analysis was done separately for data from dawn and dusk.
