We present in this paper accurate positions of 857 sources derived from 
the astrometric analysis of 16~eleven-hour experiments from the Very 
Long Baseline Array imaging and polarimetry survey at 5 GHz (VIPS). 
Among observed sources, positions of 430 objects were not determined 
before at a milliarcsecond level of accuracy. For 95% of the sources 
the uncertainty of their positions range from 0.3 to 0.9 mas, with 
the median value of 0.5~mas. This high accuracy is substantiated 
by the comparison of positions of 386 sources that were previously 
observed in astrometric programs simultaneously at 2.3/8.6 GHz. 
Surprisingly, the ionosphere contribution to group delay was adequately 
modeled with the use of the total electron contents maps derived from 
GPS observations and only marginally affected estimates of source 
coordinates.
