The current and next observation seasons will detect hundreds of gravitational waves (GWs) from compact binary systems coalescence at cosmological distances. When combined with independent electromagnetic measurements, the source redshift be known, we able to obtain precise measurements Hubble constant $H_0$ via distance-redshift relation. However, most observed mergers are not expected have counterparts, which prevents a direct measurement. In this scenario, one possibilities is use dark sirens method that statistically marginalizes over all potential host galaxies within GW location volume provide probabilistic source. Here presented $H_{0}$ using two new compared previous analyses DECam data, GW190924$\_$021846 GW200202$\_$154313. photometric redshifts possible these events acquired Local Volume Exploration Survey (DELVE) carried out on Blanco telescope Cerro Tololo in Chile. combination posterior GW200202$\_$154313 together bright siren GW170817 leads $H_{0} = 68.84^{+15.51}_{-7.74}\, \rm{km/s/Mpc}$. Including improves 68% confidence interval (CI) by 7% alone. This demonstrates inclusion well-localized such analysis precision can made. Using sample containing 10 during third LIGO/Virgo run, determine measurement 76.00^{+17.64}_{-13.45}\, \rm{km /s/Mpc}$.
