Abstract
To determine the absolute position of radio sources, the geometrical mounting error as well as the phase errors of the equipment must be known. In the case of a two-antenna interferometer these errors may be fairly accurately estimated if a few radio sources are observed in upper, as well as in lower, culmination.
