Abstract

Although the GPS technology is getting better, it is not precise enough to complete first order levelling. This technology is still an important issue these days. Since 1995 it is possible to compute the geopotential values of levelling points in Hungary. The geopotential numbers can be used for geoid determination and to determine any kind of metric heights. In this article some methods for adjusting levelling networks using geopotential numbers are presented and compared. The `best´ solution can be used later for any purposes.
