Geoscience Australia currently retains the role of the International GNSS Service Analysis Centre Coordinator (IGS ACC) in collaboration with Massachusetts University of Technology (MIT). The role is being transitioned to NASA and GA during 2025. The IGS ACC is responsible for monitoring the quality of products submitted by individual analysis centers and combining them to produce the official IGS products. The IGS ACC also has the overall responsibility for coordinating the changes, developments and improvements within the contributing analysis centers to produce the IGS products using the latest models and standards.
This report details the IGS ACC activities over 2024, which included transition of the ACC operational capability to NASA, evaluation of new products set by the European Space Agency (ESA) as one of the analysis centers, general quality assessment of the IGS combined products over 2024, and multi-GNSS demonstration combined orbits.
