  It is shown how the fundamental gaugino and higgsino parameters of the
chargino and neutralino system in the MSSM can completely be determined in
high--precision experiments at e+e- linear colliders even if in their initial
phase only the light charginos $\tilde{\chi}^\pm_1$ and the light neutralinos
$\tilde{\chi}^0_1$ and $\tilde{\chi}^0_2$ are kinematically accessible.
