By Nicholas Gowans and Volker Janssen AUSPOS is Geoscience Australia’s free online Global Positioning System (GPS) processing service. It takes advantage of the International GNSS Service (IGS) core network station data and products (e.g. final, rapid or ultra-rapid orbits depending on availability) together with Continuously Operating Reference Stations (CORS) in and around Australia.

By Dr Volker Janssen The Receiver Independent Exchange (RINEX) format is the international standard for the storage and exchange of Global Navigation Satellite System (GNSS) data. It allows efficient and unambiguous archiving of GNSS data and associated metadata in one place (in a human-readable form), while also facilitating the easy transfer and distribution of such data, independent of the equipment used and the data processing software employed.
