Charginos $\chi_1^\pm$ are expected to be the lightest observable supersymmetric particles in many supersymmetric models. We present a procedure which will allow to determine the chargino mixing angles and, subsequently, the fundamental SUSY parameters $M_2, \mu$ and $\tan\beta$ by measurements of the total cross section and the spin correlations in $e^+e^-$ annihilation to $\chi_1^+ \chi_1^-$ chargino pairs.
