Horizontal coordinates transformation and residuals modelling on the territory of the Republic of Srpska

Abstract

Horizontal coordinates transformation and residuals modelling on the territory of the Republic of SrpskaThe paper describes the optimal model for coordinate transformation between ETRS89 and old national reference system in the Republic of Srpska. The Helmert`s parameters were estimated, based on a set of 1 741 common points.The average magnitude of residuals was 0.3 m per coordinate and the residual vectors were homogeneous at the local level. The basic model was complemented by a corrections grid that uses bilinear interpolation. The accuracy of the transformed horizontal positions obtained by this model is about 10 cm. In this way, a link between the ETRS89 and local reference system has been established on the overall territory of the Republic of Srpska.

CORS Networks, Aspects of Business Models in Europe and the Region

“…Mutual data exchange is carried out to provide adequate geometry for both networks, so SRPOS uses the data of additional eight FBiHPOS stations. Data is exchanged with the networks of permanent stations in Croatia, Serbia, and Montenegro -CROPOS, AGROS, and MontePOS -in order to connect the BiHPOS network with the EPN and to improve service coverage in border areas [21]. The FBiHPOS network was expanded with two additional permanent stations and is characterized by the following [22]:  19 permanent GNSS stations;…”
