We performed a multifrequency and multiepoch study of the quasar PKS 1510-089 with ground and space VLBI, in order to study its nuclear properties and test current models for the production of the emission at X- and γ-ray energies. A preliminary analysis of our images suggests that the lower limit to the Lorentz factor γ at the distance of ∼ 12 pc from the central engine is γmin = 5. We used Ho = 100 km s−1 Mpc−1.
