Transformacije med slovenskimi in mednarodnimi terestričnimi referenčnimi sestavi

Berk, Sandi (author), Medved, Klemen (author)

Aktualen slovenski terestrični referenčni sestav (D96- 17) je statičen sestav, ki temelji na tehnologiji GNSS. Njegova posebnost je, da ga z novo realizacijo ETRS89, ki jo je potrdil EUREF (D17), povezuje dodatna transformacija. Za zagotovitev visokokakovostnega državnega terestričnega referenčnega sestava je nujna povezava z aktualno realizacijo ITRS. To je še posebej pomembno ob predvidenem prehodu na polkinematičen terestrični referenčni sestav, ki bo podprt z državnim geokinematskim modelom. V pričujočem prispevku so podrobno obravnavane transformacije med aktualnima državnim in mednarodnim terestričnim referenčnim sestavom. Podani so postopki, enačbe in parametri datumskih transformacij, in sicer v obe smeri (naprej in obratne), po korakih in neposredne, stroge in poenostavljene (približne). Predstavljeni sta analiza koordinatnih razlik med slovenskim in mednarodnim terestričnim referenčnim sestavom ter analiza točnosti različnih poenostavitev transformacij med obema referenčnima sestavoma. Slednja omogoča optimalen izbor transformacijskih rešitev glede na različne zahteve uporabnikov. Prikazana sta tudi vloga in pomen obravnavanih transformacij pri postopkih določanja položaja in pri natančni navigaciji.

• Title: Transformations between the Slovenian and international terrestrial reference frames

Abstract

The current Slovenian terrestrial reference frame (D96-17) is a static frame based on GNSS technology. An additional transformation connecting it with the new realisation of ETRS89 accepted by EUREF (D17) gives the D96-17 a specific character. In order to ensure a high-quality national terrestrial reference frame, connection to the current realisation of ITRS is needed. This is particularly important in the light of the intended transition to a semi-kinematic terrestrial reference frame, supported by a national geo-kinematic model. Transformations between the current national and international terrestrial reference frames are discussed in detail in the present paper. Processes, equations, and parameters of datum transformations are given in both directions (forward and inverse), step-by-step and direct ones, rigorous and simplified (approximate). Furthermore, an analysis of coordinate differences between current Slovenian and international terrestrial reference frames and an analysis of coordinate errors for various simplifications of transformation between both reference frames are given. This allows users to choose an optimal transformation solution to meet their requirements. The role and importance of transformations under consideration in the positioning procedures and in the precise navigation are also addressed.
