The event characteristics of chargino pair production at e+e- collisions are explored to determine gaugino-higgsino mixing angles. We demonstrate that by measuring total cross sections and left-right asymmetries with polarized beams or angular correlations among chargino decay products the fundamental SUSY parameters M_2, \mu and tan(beta) can be uniquely determined in a model independent way.
