Abstract

The mathematical correction of geodetic observed results in astrogeodetic network is one of the important bases for building the National Geodetic Information System. The correction of adjustment results due to the changes of observations (e.g. addition to the new observations, removing the old observations due to the missing of geodetic points) requires completed adjustment methods with a request that don’t re-adjustment the entire of astrogeodetic network. This paper discusses the method and the process to correct the adjustment results as required to remove the observed directions related to the missing astrogeodetic points and to add the new observations related to the geodetic points which are built on the field.
