During the Proba-V mission (7 May 2013 - present) two campaigns were led to measure angular distributions of protons at various positions in the South Atlantic Anomaly (SAA): 1st from June 2013 - January 2014 and 2nd from December 2017 - February 2018. The measurements were realized through rotation of the satellite, to adjust the EPT viewing direction with respect to the magnetic field,...
The PAMELA mission has recently measured the fluxes of geomagnetically trapped protons with energy between 80 MeV and a few GeV at low Earth orbit (350-610 km). Data were analyzed in the frame of the adiabatic theory of charged particle motion in the geomagnetic field. Flux properties were investigated in detail, providing a full characterization of the proton radiation in the South Atlantic...
An inverse method for the calculation of particle fluxes from space radiation monitor data is presented. The GenCORUM (Genetic Correlative Unfolding Method) employs tools from the fields of Artificial Intelligence and Machine Learning and manages to provide physically meaningful differential spectra of proton and electron fluxes in wide energy ranges with high energy resolution. Results are...
We give a detailed description and the main results of the electron spectrometer placed onboard the Demeter satellite. This detector with a large geometrical factor is aimed to measure electron fluxes close to 90° pitch-angles in the energy range from 70 keV to about 0.8 MeV and to provide information on the electron fluxes between 0.8 and 2.5 MeV. In survey mode, the energy resolution, about...
Satellite engineers, operators, and radiation belt researchers share a common desire to understand and predict the structure and variability of Earth's radiation belts. In the radiation belt community, there is a need for improved scientific understanding of the radiation belts, more accurate dynamic and climatological models, space weather restitution and prediction and a mechanism for more...
A review of the Internal Charging Current Measurements from SURF-like units on-board different satellites, such as Galileo, Giove-A, STRV1d and Van Allen Probes will be presented. Methods on the calculation and the validation of derived electron fluxes from these measurements will be demonstrated.
