Now in its second decade, the Aus Gov Data Summit is dedicated to advancing the government’s agenda of leveraging data as a national strategic asset. This premier event aims to empower Australian public service data leaders to elevate their missions, increase efficiency, and deliver exceptional public services.

With more than 500 leaders from federal state, and local governments expected to attend, the summit will feature an expanded program with four dedicated streams: C-suite, data and analytics, ICT leadership and innovation, and cybersecurity. Each stream is specifically tailored to address the critical challenges and opportunities within the Australian public service data ecosystem.

The third International Association of Geodesy (IAG) Commission 4 Symposium will bring together scientists, researchers and professionals working in the broad field of positioning and its applications.

The symposium will serve as a platform for discussing research that leverages current and emerging positioning techniques and technologies. It aims to provide both practical and theoretical solutions across a wide range of topics.

Discussions will address both technical and institutional aspects of developing GNSS backup systems, integrated positioning solutions, resilient PNT systems, and emerging LEO-based PNT techniques. The symposium will also explore space weather monitoring and forecasting through both ground-based and space-based geodetic observations. Additionally, the application of machine learning and artificial intelligence in geodesy will be examined.

The main topics to be covered include:

• Multi-frequency and multi-constellation GNSS technique
• Terrestrial and satellite-based positioning system development
• Multi-sensor fusion navigation and integrity monitoring
• Emerging positioning technologies, e.g., resilient PNT and LEO-based PNT
• Atmospheric space weather monitoring using geodetic observation techniques
• Applications of geodesy to engineering
• Artificial Intelligence technique for geodesy research

The International Geoscience and Remote Sensing Symposium (IGARSS) is the flagship conference of the IEEE Geoscience and Remote Sensing Society (GRSS).

The theme of IGARSS 2025 is One Earth, reflecting the focus the event will have on addressing the threats our Earth faces, and how collaborative global use of remote sensing technology can offer solutions.
