This network includes stations, both public and private, of our vicinity. In this way the user accesses an infrastructure of higher density, and has several connection options, as our own data are exchanged with new networks as Bizkaia, Euskadi, Teria and RedGAE. Includes GNSS data from stations of the National Geographic Institute of Spain, derived from RRGG CC BY 4.0 ign.es

The network is set up with distances less than 20 km from any point in Gipuzkoa which means that centimetric accuracy can be achieved in real time in geodesic and topographic studies.

Since 2005, the Network processes weekly solutions, monitors the received observations and the generation of real-time corrections.

Each GNSS Reference Station stores RINEX data for post-processing and generates simple base corrections (RTK) : CMR +, RTCM 3.0 RTCM2.3  via NTRIP protocol, together with network corrections (NRTK): iMAX, MAX, and VRS. To obtain information about the stations, click on their location. Users can also download RINEX data from the BIDA station of the Bidasoa Institute in Irun.

  • 1997
    Gipuzkoa installs its first Continuous GPS Station, called GFA, on the roof of its headquarters.
  • 2005
    In this urban environment, the GFA station was losing satellite visibility and, as a result, it was replaced by a network of three GPS stations: ELGE, LAZK and IGEL, in conjunction with the Municipality Councils of Elgeta and Lazkao, and the Igeldo Meteorological Observatory.
  • 2007
    The network is updated to also manage GLONASS signals as well as GPS, and a new station, PASA, is incorporated in the AZTI facilities in Pasaia.
  • 2015
    The PASA station joins the EPN network (EUREF Permanent GNSS Network) that defines the Geodetic Reference Frame in Europe. It is the only EPN station in the area; the nearest EPN stations are in Ciboure, Logroño and Santander.
  • 2016
    The four stations in the network are upgraded to receive Galileo and BeiDou signals.
  • 2017
    The network integrated in 2015 in EPN Densification begins to obtain combined solutions from 3 Analysis Centers.
  • 2019
    The network is incorporated into the EPOS (European Plate Observing System) infrastructure.
  • 2022
    Since mid 2008, users have connected to the network 286,689 times. The Gipuzkoa GNSS Network handles an average of 82.6 connections of 54.5 minutes duration per working day.
