Implementation of the ETRS89 in Europe: Current Status and Challenges
International Association of Geodesy Symposia, 2015The EUREF (Reference Frame Sub-Commission for Europe) Permanent GNSS Network (EPN) serves as the backbone for the realization of, and access to, the European Terrestrial Reference System (ETRS89). The cumulative site positions and velocities for the EPN stations are used for national ETRS89 densifications and geo-information applications.

A RANGE OF ED50-ETRS89 DATUM TRANSFORMATION MODELS TESTED ON THE SPANISH GEODETIC NETWORK
Survey Review, 2006AbstractA set of datum transformation models for performing ED50-ETRS89 datum transformation in Spain are presented. These comprise 5/7 parameters, complex and real polynomials and distortion modelling. The latter case includes several tests using external points for the three methods explored: Rubber Sheeting, Minimum Curvature Surfaces and Least ...

The present paper presents a geodetic datum transformation between the old and new national coordinate reference systems of Slovenia. The basis for transformation is a set of about 2000 points coordinated in both systems. Virtual tie points are used, which form a regular triangular network covering the entire country.

The problem of temporal validity of reference coordinates in the context of reliability of the ETRS89 system realization in Poland [PDF]
Artificial Satellites, 2012 ABSTRACT The IAG (International Association of Geodesy) Sub-Commission for the European reference frame (EUREF) passed a resolution recommending application of the ETRF2000 frame as national realizations of the ETRS89 reference system during the XXth EUREF Symposium in Gävle (Sweden) in 2010. The PL-ETRF2000 system is comprised of EPN

In this paper a simple method for accurate transformation of geodetic coordinates is presented. The process uses the regional network of points allocated in both geodetic systems researching only the two-dimensional problem (longitude and latitude). Basically, transformation of any point P consists to determine first the three network vertexes nearest ...

Síť trigonometrických bodů I. řádu JTSK a její propojení s realizací systému ETRS89 v ČR
Družicové metody v teorii a praxi 2024The JTSK First order trigonometric points (TP) network was being built on the Czechoslovakia territory between 1921 and 1953.Its initial implementation was completed in the spring of 1927 and included 268 trigonometric points, which thus form the basic framework of the Czechoslovak positional geodetic control.

The IAG Reference Frame Sub-Commission for Europe (EUREF) created the European Terrestrial Reference System 89 (ETRS89) and fixed it to the Eurasian plate in order to avoid time evolution of the coordinates due to plate motions. However, the Fennoscandian area in Northern Europe is affected by postglacial rebound (PGR), causing intraplate deformations ...

Кинематична реализация на ETRS89, епоха 2005 за територията на Република България
2021Темата и разработките в дисертационния труд са насочени към кинематична реализация на общоприетата на стария континент Европейска земна референтна система – ETRS89, на територията на България. Това се състои в определяне на действителните скорости на точките, които се явяват практическа реализация на координатната система на територията на страната ...
