and with a view to having an adequate density of stations
throughout the national territory, the IGN shares with other
institutions some of its stations of the ERGNSS network. The
institutions that share these facilities are Autonomous Com-
munities and Ports of the State through collaboration agree-
ments. In the following list the institutions that share sta-
tions are mentioned.
Services of the ERGNSS network: Post-process services : in
the form of RINEX files of all stations, with different inter-
vals (hours at 1, 5, 10 and 30 seconds or daily to 30 seconds),
accessible by the user in different ways:
-
Directly through an
server.
-
Through this web page in the utility
.
-
Through the
.
•
Real-time positioning services: by connecting to the
different “streams” of data available in the Real-Time
Services section. They allow instant precise positioning
for the user by connecting through the Internet to the real-
time servers of the IGN. For more detailed information,
consult the
page.
GNSS data analysis center: The IGN is a GNSS Data
Analysis Center that performs continuous data processing
for several projects from both the permanent stations of
the ERGNSS network and from other networks, as well
as being a EUREF Local Analysis Center (acronym IGE)
from September 2001. The different continuous calculation
processes for these projects are carried out in Bernese 5.2,
they are automated. For any query about the geodesy services
provided by the National Geographic Institute and the GNSS
Permanent Station Network, the contact is
