Description
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, before the satellite enters the targeted bins (three bins were selected).
The objective of the off-pointing measurements in 2017 was twofold: 1) to better characterize the performances of the instrument after its recalibration in summer 2014, and 2) to extend the angular distribution study to regions of higher L and B but without approaching the boarder of the SAA where atmospheric effects, like east-west asymmetry, are observed.
During the presentation, the data analysis will be exposed and for the three position bins under investigation, comparison with AP8 and IRENE/AP9 will be shown and differences discussed.
Additionally, new SSA Proba-V/EPT radiation modelling linked products will be presented.
