European vertical and gravimetric reference systems

Abstract

The paper provides an overview of height and gravity reference systems of Europe and a brief description of their implementation. For each system we have given definitions of the system, as well as changes in definitions over time. In paper we have briefly described European Vertical Reference System-EVRS, United European Leveling Network-UELN, European Vertical Reference Network as well as densification action - EUVN_DA. Gravimetric reference systems are described by the Potsdam reference system, through a system IGSN71 (International Gravity Standardization Network 1971), as well as a series of actions aimed at defining a new gravity reference systems of Europe.

U radu je dat pregled visinskih i gravimetrijskih referentnih sistema Evrope i kratak opis njihovih realizacija. U opisu svakog sistema date su definicije sistema, kao i promene definicija u vremenu. U pogledu visinskih sistema i mreža dati su kratki opisi EVROPSKOG VERTIKALNOG REFERENTNOG SISTEMA (European Vertical Reference System - EVRS), UJEDINjENE EVROPSKE NIVELMANSKE MREŽE (United European Leveling Network-UELN), EVROPSKE UJEDINjENE VER- TIKALNE MREŽE (European Vertical Reference Network-EUVN) i akcija koje se izvode u cilju njenog progušćavanja (European United Vertical Network - Densification Action - EUVN_DA). Gravimetrijski referentni sistemi opisani su od Potsdamskog referentnog sistema, preko sistema IGSN71 (International Gravity Standardization Network 1971), kao i nizom akcija u cilju definisanja novog referentnog gravimetrijskog sistema Evrope.
