PAVI – GNSS permanent station
The Laboratory of Geomatics has been operating such a GNSS permanent station since 1999. which is called PAVI (due to international standards, names must be have four letters).
A permanent station is a GPS/GNSS receiver shich works 24h/365, observes the satellite constallations and store the received data. The acquired data are freerly available for surveyors and researchers.

PAVI is part of two very important GNSS networks:
- RDN (Rete Dinamica Nazionale) which represents (embodies) the geodetic frame in Italy. More information can be found on official website (RDN website – Italian only).
- the Piedemont-Lombardy GNSS network, supplying the so-called NRTK corrections, allowing professional surveyors to quickly perform high-quality measurements.More information can be found on the official website (www.spingnss.it).

Monumentation
Officially, PAVI started to observe GPS contallation in novembre 11th 1999 and during last years several receivers and antennas had been changed.
Now PAVI is equipped with a TopCon TPS NET-G5 receiver and a TPSCR3 antenna. For more information about PAVI’s history please download the LOG file (“Log_file_PAVI.txt“).
PAVI’s antenna through the years
- Trimble D/M chock ring
- Trimble Zephyr Geodetic
- Leica D/M chock ring
- TopCon TPSCR3
PAVI’s antenna was anchored to a structural part of the main university building.
