The estimation of Solar system acceleration from VLBI-observations was obtained. Obtained value compared with the results of other authors. Calculation was performed by the global adjustment of the VLBI data using QUASAR software. The estimated value of acceleration vector a = (4.7 ± 0.5) · 10^−10 m/s^2 in direction α = 288±5, δ = 0±5 significantly differs from the theoretical one but comparable with the other results
