dc.descriptionWe report on the present status of our S5 polar cap phase-connected astrometry program. We observe 13 radio sources in the northernmost 20deg of the sky at the wavelengths of 3.6cm and 2cm, and we plan to extend the program to 0.7cm. We phase-connect jointly all our data successfully. We image the radio sources and some of them show morphological changes, in which astrometric registration is needed to determine the kinematics of the source components. We aim at unprecedented astrometric accuracy and at a check of the jet standard model at the 5-10 microarcsec/yr level.
