Abstract

We present a multi-calibrator solution, i. e. MultiView, to achieve accurate astrometry on the level of the thermal noise at low VLBI frequencies dominated by ionospheric residuals. We demonstrate on L-band VLBA observations how Multi- View provides superior astrometry to conventional phase referencing techniques [1]. We also introduce a new trial method to detect antenna based systematic errors in the observations [2]. All presented methods and results are based on our recent papers [2, 1].
