ABSTRACT
Since an renewal of the Croatian height reference system is necessary the Republic of Croatia should engage in the design and survey of a new fundamental levelling network. However, a factor significantly limiting the levelling network design seems to be the negative correlation between the specific shape and the size of the Croatian territory compared to the standards of realization of levelling networks having a compact and firm geometrical configuration. In order to examine the potential ways of resolving this issue, a simulation of the height reference system realisation was performed, by means of the revised fundamental levelling network which had originally been used to create the current official height reference system of the Republic of Croatia.

Keywords: height system, levelling network, adjustment, height accuracy, Croatia.
