AB: On December 7th 1995, the Galileo mission began the study the jovian system. Among the results that his mission has obtained, it is the evidence of the existence of a liquid water ocean beneath the icy crust of Europa. Liquid water is one of the main factors that make life possible, so then life might exist in Europa. Some of the scenes that have been settled out to explain how living organisms could be present in such an extreme environment involve suppositions about the width of the icy crust. The explanation of other geological structures on the satellite also implies an estimation of the crust's width, that is why a good estimation about this parameter is very important in the geological study of this satellite. In this work, we analyze one electrodynamic model of the crust considering a two layered crust. The purpose is to obtain the optimal electrophysical parameters of measurement that permit us to estimate the crust's width. These parameters are calculated from the inverse elements of the Fisher matrix. The results obtained from this work can be used to plan future space missions to jovian satellites (in particular it could be useful for JIMO mission). The optimal algorithms for these measurements can be modified to be used in active systems of remote sensing.
