The measurement of the gluon contribution to the nucleon spin {delta}G is one of the main goals of the COMPASS experiment located at the CERN Super Proton Synchrotron. The key reaction is the photon gluon fusion to D (D-bar) -mesons. The status of the analysis of the D0- and D*-events is shown as well as the expected statistical error of {delta}G/G from the first 3 years of data taking.
