- Abstract
co-authors to be added. The electron environment at MEO altitude is very hard, intense and dynamics. Such an environment implies a strong constrain and overcost for MEO spacecraft design and operations. Having a good knowledge of this environment in the outer electron belt is needed but it is a challenge. To reach this goal Los Alamos National Laboratory data acquired since the early nineties to present on-board GPS birds have been used. First data have been analysed in details in term of saturation, contamination, global coherence ... to ensure high fidelity for any future use. Then year averaged data along GPS orbit have been performed over more than a solar cycle and an electron model from 200 keV to 1.2 MeV have been developed. Finally electron flux level predicition with this new model available at MEO altitude has been compared with the NASA/AE8 model and with the electron GEO model POLE.
