General info

At the present time, the network is composed by ten permanent stations located throughout the region and operating 24 hours a day, seven days a week; the choice of the locations of the ten sites was evaluated on the basis of both technical-methodological and logistical criteria. Among the technical and methodological requisites examined for evaluating the suitability of a site to host a permanent station can be cited the absence of obstacles or electromagnetic disturbances that could reduce the signal-to-noise ratio (SNR), the lack of possible sources of multipath interference, the static reliability of the sites, and their geographical distribution for obtaining an optimal coverage of the territory.

From a logistical point of view, it was decided to place the permanent GNSS stations at peripheral offices of the Regional Administration in order to ensure direct accessibility to the instrumentation, the continuity of electrical supply, and connection to the regional telematics network.

The control centre at the Regional Data Centre in Trieste has the following functions: monitoring of the activities of the permanent stations; management of the data streaming coming from the permanent stations, and the formatting of files for post-processing differential correction; reception of signal for the real-time correction of the permanent stations, implementation of VRS, MAC, and iMAC services, and their distribution via the internet utilising the Ntrip Protocol; web server for access to RINEX files; Ntrip caster.

The telematics connections between the permanent stations, the control centre, and the internet are made using the regional infrastructure.

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 any possible modification to the service or to documents that are corollary.
