Combining gravitational-wave and electromagnetic data with new radio observations of GW170817, an improved measurement of \(H_0 = 70.3_{-5.0}^{+5.3}\, {\mathrm{km}}\, {\mathrm{s}}^{-1}\,{\mathrm{Mpc}}^{-1}\) is derived. Fifteen more GW170817-like events with radio data could resolve the Hubble constant tension.
