Dear colleagues,
the University of Perugia manages two GPS+GLONASS permanent stations: UNPG
and UNTR, that are part of EUREF Permanent Network and EUREF-IP. In
particular UNPG is part of EPN since 1999 and part of EUREF-IP since 2006.
With the present mail, I formally ask that UNPG became an IGS station. There
are a number of valid reasons supporting the proposal.
UNPG is located in the centre of Italy (about 130 kilometers from Rome) so
it is able to fill a gap of the IGS network in Italy, because most all the
existing IGS stations are located in Northern and Southern Italy. The UNPG
station is equipped with a choke ring antenna (Regant_DD_E), an Odyssey-RS
(GPS+GLONASS) receiver, meteo sensors, an external frequency, a server that
manages the station and an UPS.
UNPG is the GNSS permanent station of the University of Perugia, so I'm
confident that there aren't problems to maintain and upgrade this station in
future.
The station respects all the strictly required IGS site guidelines, but UNPG
satisfies a lot of the additionally characteristics too. The receiver has
been already set for all-in-view tracking and the antenna is known to the
IGS. The UNPG station is also equipped with an external frequency device
(rubidium clock), a Vaisala meteo (pressure, temperature and humidity)
sensors (satisfying the guidelines for IGS sites submitting metereological
data) and an UPS backup power system to protect the station against power
failures. The UNPG receiver tracks GLONASS satellites.
The station collects hourly and daily files with a sampling rate of 30
seconds for EUREF (but can be produced files with the desired sampling rate
up to 1 Hz and with the desired duration). It's possible to set the data
delivery to two or more IGS centers.
The distance from the nearest station (Matera) in the South of Italy is
about 600 Km and the distance from the nearest station (Medicina) in the
North of Italy is about 200 Km. In Italy there are only four IGS GPS/GLONASS
permanent stations, UNPG could be the fifth one.
The UNPG station is able to take part to the LEO-PP Project, because it's
possible to send data with a rapid delivery (hourly to <15 minute, near
real-time or data streaming), our station could also take part to
IGLOS-Pilot Project because the station tracks GLONASS constellation.
Finally, it could participate to IGS-IP, because it is already part of
EUREF-IP. UNPG station can also send hourly data and meteo data, that are
surely useful for a lot of IGS activities.
The UNPG station is also a vertex of the ETRS89/IGM95 network of Umbria
Region, densifying the national geodetic network IGM95, so it is strictly
connected to the National Italian Datum Reference System (Roma40).
The UNPG is described in in its webpage in the EPN website
(
http://www.epncb.oma.be/_trackingnetwork/siteinfo4onestation.php?station=UNPG_12752M001
) and in the web page of the local network, named Labtopo, that is managed
from our staff of the University of Perugia
(
http://labtopo.ing.unipg.it/labtopo). In the latter web page is possible to
select the sampling rate among 30 s, 5 s and 1 s and freely download the
data in the Hatanaka compact Rinex compressed (.Z) format .
For EPN, UNPG is sending data to ASI and BKG, but it is possible to add or
change data center.
I attach in this email the UNPG site log file.
I add further information about the people you can contact for the station:
