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 INTERGEO EXPO and CONFERENCE brings together hundreds of exhibitors and thousands of delegates from around the world, to discuss with, learn from and network with others in the sectors of geodesy, geoinformation and land management.

The event presents an opportunity for vendors to showcase their innovative geodata-based solutions to an international audience over three days, addressing current challenges such as climate change, urbanisation and sustainable land use.

The 2024 event in Stuttgart attracted more than 550 exhibitors and more than 17,000 visitors.

INGEO 2025, the 9th International Conference on Engineering Surveying, continues the series of meetings that began in 1998.

The aim of the conference is to bring together professionals in the field of engineering surveying and other related professions, such as civil engineering, mechanical engineering, geoinformatics, geotechnics and so on, to discuss new technologies and development.

The main topics of discussion will be:

• 3D modelling of buildings and engineering structures, BIM
• Smart cities, data collection, sensors, ISs and IOT applications
• Cultural heritage documentation, data collection, 3D modelling
• Indoor navigation (SLAM, RFID, TOF, etc.), low-cost systems and applications
• Deformation measurement, automated measuring systems
• Industry surveys, application of modern technology for power plants, nuclear facilities, etc.,
• Standards and quality assurance of engineering surveys

The Positioning, Navigation and Timing 2026 (PNT2026) conference will be held at Sydney’s Royal Randwick Racecourse from 4 to 6 February next year.

Formerly known as the IGNSS Conference, PNT2026 will bring together local and global experts from industry, government, defence and academia to showcase and discuss the latest advancements in GNSS and alternative PNT technologies.

Key industry challenges will be on the agenda, as will applications across the aerospace, defence, smart city, autonomous systems and critical infrastructure sectors, and others.

This will be the first event of its kind since the International GNSS Association (IGNSS) merged with the Australian Institute of Navigation.
