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 Open Geospatial Consortium’s (OGC) 132nd Member Meeting will be held from June 9 to 12, 2025, at the Holiday Inn Mérida in Mérida, Yucatán, Mexico.
The event will feature several tracks on a variety of topics, especially innovation in geospatial interoperability.
The program will highlight how remote sensing technologies such as synthetic aperture radar, LiDAR and hyperspectral sensing are contributing to societal, economic, security, and disaster response scenarios.
The program will also explore how digital transformation is improving land administration and building information management.
