Founded in 1999 with the objective of providing assistance for the georeferencing in advanced systems of geographical features to be positioned on regional cartography, the GPS network of the Region FVG has, from the outset, represented an essential instrument for all those regional offices whose responsibility is to carry out topographic measurements or localise relevant elements for the management and planning of the territory.

Initially composed of only three permanent stations (with Palmanova as the regional barycentric point, and Ampezzo and Moggio Udinese as reference points in the mountain areas), the configuration of the network has been upgraded and finalised in successive phases to reach the current structure of ten stations that guarantee the complete coverage of the regional territory. The first upgrade in 2005 brought a technical adjustment of the GPS receivers in order to make evolved instrumentation available, along with an architectural modification of the management software. The improvement of the technological communication infrastructure was another key point of that intervention, ensuring that all the permanent stations were connected to the control centre via HDSL technology. New services were made accessible on the internet in a completely open and free way also for private users (freelance professionals, technicians, companies, universities); in particular, RTK real-time differential correction utilising the Ntrip protocol was activated.
In the upgrade of 2007 the network was expanded to link 10 stations, and slight modifications were made. There was also a further augmentation of the real-time positioning service by making the VRS (Virtual Reference Station) methodology available that enables improvements to be made to the positional accuracy of corrections provided to users of the GPS FVG network. In the course of 2012 the instrumentation was completely renovated, expanding and optimising the network functionality. The intervention has enabled every station to manage, in addition to data from the GPS constellation, both GLONASS and GALILEO. The real-time positioning services have been expanded, making the correction data stream available for MAC type and the RTCM 3.1 format

In November 2012, the permanent station in Palmanova ceased operation. It was replaced, in June 2013, by a new structure in Cervignano del Friuli.

The Trieste permanent station has operated from 26 May 2003 to 23 November 2016 at the regional office in Via Monte San Gabriele 35, from 20 December 2016 has therefore taken - operationally speaking - his place the "TRSE" station in via Cantù 10 always in Trieste.
The GNSS Network of the Autonomous Region Friuli Venezia Giulia "A. Marussi "is framed in the national geodetic system called RDN ETRS89-ETRF2000 the day February 24, 2017.

The elevations refer to the base of the antenna "BAM" (Bottom of Antenna Mount).

It should be noted that the Region of Friuli Venezia Giulia provides the service of the permanent GNSS station network free of charge. The Region reserves the right to make, even without prior warning, any possible modification to the service (service, understood here, both in its entirety, and in each of its component parts), or to documents that are corollary, and possibly even suspend the service itself without prior warning, without incurring liability for any damages
