    National height reference coordinate systems are based on levelling networks classified into orders, according to their accuracy. Traditionally, height systems are realized by applying the parametric ... adjustment and the least squares method. Any kind of correlation between the observations as well as the correlation of fixed heights is often neglected for pragmatical reasons. Also, given heights are usually assumed error-free when in reality they possess a certain level of accuracy. This paper presents an alternative realisation of the height reference system HVRS71 for the Republic of Croatia. Data scope is limited to the 1st and the 2nd order levelling networks. Alternative realisation is carried out by applying different adjustment concept where the correlations between the observations caused by the introduction of correlated given heights are considered. Also, this methodology enables the transfer of the accuracy of benchmarks’ absolute heights from the higher-order levelling network to the accuracy of the benchmarks’ absolute heights of lower-order levelling networks. Thus, an objective, logical and real distribution of the benchmarks’ height accuracy along the scope of the height reference system is achieved. The results specify to what extent the change in the concept of the levelling network adjustment affects the quality of the height reference system.
