Abstract：
We propose alternative methods for measurement of the global polarization of $\Lambda$ hyperons. These methods involve event averages of proton and $\Lambda$ momenta in the laboratory frame. We carry out simulations using these methods and show that all of them work equally well in obtaining the global polarization of $\Lambda$ hyperons.
