AbstractPolar Earth Orbit (PEO) is a peculiar orbit where energetic auroral electrons and low-temperature ionospheric plasma coexist. There is a risk of charging and subsequent arcing in PEO, which was demonstrated unfortunately by the total loss of ADEOS-2 (ADvanced Earth Observing Satellite-2: Midori-2) satellite in 2003. Charging in PEO must be properly assessed in the early satellite design phase by a spacecraft charging analysis tool. The plasma environment, namely its density and energy, is the crucial parameter for the spacecraft charging analysis. The balance between the auroral electrons and the low temperature ionospheric ions determine the charging potential of a PEO satellite. We statistically analyzed the environmental condition in PEO using the data of auroral electrons and thermal ions measured by DMSP (Defense Meteorological Satellite Program) satellites. Probability of a given combination of current densities of auroral electrons and thermal ions has been derived. The energy spectrum of the auroral electrons are also classified into several types and correlation with the thermal ions is analyzed. Combinations of the plasma parameters used by a spacecraft charging simulation software have been identified and database regarding the probability of occurrence of each combination has been formulated.
