Abstract

Proposal of Zero Order Gravity Network of the Republic of Croatia amendment is depicted in this paper. Overview on domestic regulations and international standards regarding zero order gravity networks, absolute station selection and ECGN station implementation is given. State of the present zero order gravity network is analysed. It is deduced that zero order gravity network comprises insufficient number (four) of accurately determined absolute stations that satisfy international criteria for absolute gravity station monumentation. In addition, absolute gravity measurements have been conducted 13 or 17 years ago (with respect to specific station). Accordingly, it is necessary to conduct new set of absolute measurements as soon as possible. Furthermore, a proposal of zero order gravity network amendment is given, by inclusion of four new stations (in Čakovec, Zabok, Gospić and Split) and allocation of station in Pula to Rovinj. Proposed new stations should also facilitate realisation of horizontal and vertical calibration lines as well as implementation of one or two ECGN station on Croatian territory.
