Potential utility of future satellite magnetic field data [PDF]

The requirements for a program of geomagnetic field studies are examined which will satisfy a wide range of user needs in the interim period between now and the time at which data from the Geopotential Research Mission (GRM) becomes available, and the ...

In-flight determination of spacecraft magnetic bias independent of attitude [PDF]

A simple algorithm for the in-flight determination of the magnetic bias of a spacecraft is presented. The algorithm, developed for use during the Hubble Space Telescope mission, determines this bias independently of any attitude estimates and requires no

Secular change in the geomagnetic field in West Africa of thirty years : comparison with fourth generation IGRF models [PDF]

, 1987
L'auteur compare les données géomagnétiques recueillies dans huit pays de l'Afrique de l'Ouest avec celles calculées en utilisant le modèle IGRF. Il montre que ce modèle est excellent pour déterminer les variations séculaires et qu'il n'y a pas d ...

PIC Modeling of Ionospheric Plasma Diagnostics by Hemispherical Probes: Study of the LAP-CSES at Magnetic Conjugates

Plasma
We present three dimensional particle-in-cell simulations of current-voltage characteristics of the hemispherical Langmuir probe (LAP), onboard the China Seismo-Electromagnetic Satellite (CSES).

Dependence of Simulations of Upper Atmospheric Microwave Sounding Channels on Magnetic Field Parameters and Zeeman Splitting Absorption Coefficients

Remote Sensing
The upper atmospheric microwave sounding channels data are important for atmospheric data assimilation and retrieval. However, radiative transfer simulation accuracy is constrained by the precise characterization of the Zeeman splitting effect.

Comparisons of high latitude E > 20 MeV proton geomagnetic cutoff observations with predictions of the SEPTR model

, 2002
International audienceRadiation effects from solar energetic proton (SEP) events are a concern when the International Space Station reaches high latitudes accessible to SEPs. We use data from the 20?29 and 29?64 MeV proton channels of the Proton/Electron
