The underlying project is related to the recent establishment of the Hellenic Positioning System (HEPOS), a GPS-based spatial positioning service using a network of 98 continuously operating reference stations located in Greece and operated by KTIMATOLOGIO S.A. The data analysis procedure that was followed for the least-squares adjustment of the HEPOS network is described, along with the adopted methodology for the datum definition and its alignment with the ETRS89/ETRF05 reference frame. The paper presents also a combined transformation model that was concurrently developed for the connection between the official Hellenic Geodetic Reference System 1987 (HGRS87) and the Hellenic Terrestrial Reference System 2007 (HTRS07), where the latter identifies the ETRS89/ETRF05-based frame that underlies the operation of HEPOS. The results obtained from the evaluation of the aforementioned model, at 2430 geodetic benchmarks throughout Greece, revealed an accuracy level that is better than 10 cm in terms of the rms value for the total horizontal transformation error.
