The establishment of a new gravity reference frame for Serbia

Abstract

In this paper, gravimetric work performed in the territory of Serbia is shown chronologically from the end of the nineteenth century until present. The first work, which was based on data from pendulums, is presented briefly. Details are provided on the establishment of the first order gravimetric network from 1952 and a basic gravimetric network created 10 years later. A review of a detailed gravimetric measurement, performed simultaneously with these works for establishing the networks, is also given. Special attention is dedicated to the first measurements using absolute gravimeters that were performed in 2007, but also to establishing a new basic gravimetric network as a basis for a future detailed gravimetric survey. From all of the shown data, it is to be noted that ex-Yugoslavia and then Serbia followed to a great extent modern trends of gravimetric network development. Unfortunately, the network maintenance was inadequate, and a database was not established due to the political and economic changes in the society, which caused suspension of some institutions that were authorised for these types of jobs.
