Precisioni ottenibili dall’approccio PPP mediante uso di parametri di trasformazione regionali

In this paper the main results obtained by a study on a subnetwork of the EUREF Permanent Network has been reported. The study focus the impact of different methods to align PPP solution into ITRS Reference System using both global and regional transformation parameters. In particular we demonstrate as the regional parameter transformation improve accuracy and repeatability without remove any local periodical signal detected by the permanent stations. The considered dataset is constituted by 6 years of 14 permanent stations located in Italy and neighbor regions. This work is a review of a more complete work published in 2015 in GPS solution entitled “Improved PPP performance in regional networks” by the same coauthors of this contribute.
