Services and tools

Geoscience Australia offers open-access positioning data and a range of tools and models to help you use this data and get the most out of precise positioning. These tools and models can be used for transforming and manipulating spatial and geodetic data through accessible online tools.


GNSS Data Centre

The GNSS Data Centre is a central location to access the data and products derived from Geoscience Australia’s and other regional GNSS networks. Within the Data Centre you can access historic GNSS data files, connect to real-time data streams, see the status and performance of stations and access guidelines and documentation about the network.


AUSPOS is Geoscience Australia’s free online GPS data processing capability. Users can upload dual frequency geodetic quality GPS RINEX data observed in a 'static' mode and will receive an AUSPOS report containing Geocentric Datum of Australia 2020 and 1994 (GDA2020 and GDA94) and International Terrestrial Reference Frame (ITRF) coordinates.

Antenna calibration facility

Geoscience Australia’s Antenna Calibration Facility can conduct absolute field antenna calibrations to determine the phase centre variations of the antenna, enabling high accuracy positioning from Global Navigation Satellite Systems. Find out more at our ACF page.

Regulation 13 certificates

Geoscience Australia provides a free service to assist operators to obtain Certificates of Verification of a Reference Standard of a Position-Measurement on Continuously Operating Reference Stations (CORS). These certificates are legal documents issued in accordance with Regulation 13 of the National Measurement Regulations 1999. Find out more at our Regulation 13 Certificates page.

Asia-Pacific Reference Frame (APREF)

The Asia-Pacific Reference Frame (APREF) project creates and maintain an accurate geodetic framework to meet the growing needs of industries, science programs and the general public using positioning applications in the Asia-Pacific region. Find out more at our APREF page.

Ginan: Analysis Centre Software

Ginan, the Analysis Centre Software, is the custom open-source positioning software that Geoscience Australia is developing. The Alpha version of the software is available under an open source licence from Geoscience Australia’s GitHub. This is a development version and will be upgraded to production in 2022.


GeodePy is a package of tools for manipulating geospatial datasets using Python, and is available on Geoscience Australia’s GitHub repository. The tools include transformations between time-dependent datums and common format conversions for geodesy such as between decimal degrees and degrees, minutes, seconds.

Australian Geospatial Reference System – tools and models

Geoscience Australia has developed a number of tools to assist users working within the Australian Geospatial Reference System, including: datum transformations, coordinate conversions and height conversions using geoid models. The models that these tools depend upon are also available for download.
