* Not accessible from outside Korea. † Experimental Ginan products — not official IGS combined products.
Federal Agency for Cartography and Geodesy Website: https://igs.bkg.bund.de/
Full HTTPS mirror of the IGS combined product archive. No authentication required.
Serves IGS final, rapid, and ultra-rapid orbit/clock/ERP solutions from GPS week 1
to present, merged RINEX 3 broadcast navigation, SINEX, and ionosphere (GIM) files.
Products use AAA=IGS.
Chinese Academy of Sciences — GNSS Research Center (GIPP) Website: http://www.gipp.org.cn/
CAS produces Global Ionosphere Maps (GIM, AAA=CAS) and differential code bias
(DCB/OSB) files. Products are on the GIPP FTP server at ftp.gipp.org.cn.
NASA Crustal Dynamics Data Information System Website: https://cddis.nasa.gov/
The primary IGS Global Data Center. Hosts products from all IGS and MGEX Analysis
Centers organized in GPS-week subdirectories (gnss/products/{GPSWEEK}/). Requires
FTPS (explicit TLS); anonymous login with an email address. RINEX data at
gnss/data/daily/{YYYY}/{DDD}/{YY}?/.
Center for Orbit Determination in Europe (CODE / AIUB) Website: https://www.aiub.unibe.ch/research/gnss/
CODE is one of the original seven IGS Analysis Centers. Produces precise orbits,
clocks, ERP, ionosphere maps (one of the primary GIM producers), signal biases, and
troposphere delay products. AC code COD. FTP at ftp.aiub.unibe.ch.
European Space Agency / ESOC Website: https://navigation.esa.int/
ESA/ESOC produces precise orbits, clocks, ERP, biases, and GIM products (AC code
ESA). ESA uses CNT=BIA instead of CNT=OSB in long filenames. FTP at
gssc.esa.int.
EUREF Permanent GNSS Network (EPN) Website: https://epncb.oma.be/
EPN is a European regional GNSS reference station network coordinated by the Royal Observatory of Belgium. Provides RINEX observation data from 400+ European stations and weekly SINEX coordinate solutions in ETRS89. HTTPS only — no FTP. Does not host IGS combined orbit/clock products.
Geoscience Australia Website: https://www.ga.gov.au/scientific-topics/positioning-navigation/geodesy
IGS Regional Data Center for the Asia-Pacific region. Hosts the Australian Regional
GNSS Network (ARGN) and APREF SINEX coordinate solutions. Also publishes
experimental orbit/clock/ERP products from the open-source
Ginan software (AC code GAG).
Served over public AWS S3 / HTTPS.
GFZ German Research Centre for Geosciences (Potsdam) Website: https://www.gfz-potsdam.de/
GFZ publishes OPS-only precise orbit, clock, ERP, troposphere, and SINEX
products at isdc-data.gfz.de/gnss/products/, organized into final/,
rapid/, and ultra/ weekly archives. The service is reachable via anonymous
SFTP (anonymous / anonymous@isdc-data.gfz.de). GFZ does not publish bias
files on this endpoint — use CDDIS or KASI mirrors instead.
Groupe de Recherche de Géodésie Spatiale (CNES/CLS) Website: https://igsac-cnes.cls.fr/
GRGS is a French IGS Analysis Center (AC code GRG). Produces precise orbits,
clocks, ERP, signal biases, and attitude ORBEX files. Orbits, clocks, and
attitude files must be used together as radial orbit and attitude differences
are compensated in the clock products. FTP at ftpsedr.cls.fr.
International GNSS Service — combined products Website: https://www.igs.org/
The IGS Combined Products (AAA=IGS) are produced by the Analysis Center
Coordinator and distributed via IGN France FTP (igs.ign.fr) and mirrored at
CDDIS, BKG, and KASI. The files.igs.org HTTPS server hosts supplementary files
such as ANTEX antenna calibrations.
NASA Jet Propulsion Laboratory Website: https://sideshow.jpl.nasa.gov/
JPL is one of the original seven IGS Analysis Centers (AC code JPL). Products
include orbit, clock, ERP, bias, ionosphere (GIM), troposphere, and SINEX. Available
via HTTPS at sideshow.jpl.nasa.gov/pub/jpligsac/{GPSWEEK}/.
Korea Astronomy and Space Science Institute Website: https://gnss.kasi.re.kr/
KASI is an IGS Global Data Center providing a comprehensive full-parity FTP mirror
of IGS and MGEX products from all major Analysis Centers (nfs.kasi.re.kr).
Products are organized under gnss/products/{GPSWEEK}/. KASI is a reliable
alternative/fallback to CDDIS when FTPS access is not available.
National Geographic Information Institute (Korea) Website: https://www.ngii.go.kr/
IGS Regional Data Center for the Korean GNSS network (KGPS). Hosts RINEX
observation data from Korean CORS stations. The FTP server (nfs.kgps.go.kr) is
not accessible from outside Korea. All products are marked available: false.
For Korea-region IGS products use KASI instead.
Natural Resources Canada — Canadian Spatial Reference System (CSRS) Website: https://webapp.geod.nrcan.gc.ca/
NRCan is an IGS Analysis Center (AC code EMR). Produces precise orbits, clocks,
ERP, biases, and SINEX solutions for the North American region. FTP at
ftp.nrcan.gc.ca under gnss/products/{GPSWEEK}/.
Scripps Institution of Oceanography / SOPAC Website: https://sopac-csrc.ucsd.edu/
SIO operated as an IGS Global Data Center and Analysis Center under the SOPAC
program until its absorption into EarthScope/UNAVCO in 2020. The historical FTP
at garner.ucsd.edu is no longer operational. SIO continues to contribute as an
IGS Analysis Center (AC code SIO0) — its products are available via KASI, CDDIS,
and BKG mirrors. All products in this config are marked available: false.
Graz University of Technology (ITSG) Website: https://www.tugraz.at/institute/ifg/
