The determination of physical heights by transformation of the ellipsoidal GNSS heights to the Geoid (or quasi-Geoid) height reference surface (HRS) as the 2nd component of the geodetic infrastructure for GNSS positioning services (GIPS) requires the computation of Geoid-QGeoid-models as RTCM-capable databases as a sustainable geodetic task in the establishment of GIPS. In the work, an overview is given about different GIPS components as well as realized concepts and relevant software. The authors present in detail the mathematical models of the general world-wide valid concept for the HRS computation for the mentioned models as essential part of GIPS. The concept is shown at the Baltic QGeoid over the territories of Estonia, Latvia and Lithuania. The DFHRS-software for the computation was developed at the Karlsruhe University of Applied Sciences (HSKA).
