Abstract
As showed in the document [3], the addition of astrogeodetic missing points on the field is necessary in the problem of correction the astrogeodetic data in the geodetic database for building the National Geodetic Information System. Currently, instead of the addition of astrogeodetic missing points by direction measurement, we used GPS technology. This paper discusses the making adjustment equations of the GPS observations and weighting of them, compared with direction observations in astrogeodetic network to recurrent adjustment in the problem group of restoration missing points.
