General information

The 2nd Commission 4 Symposium brings together scientists, researchers, and professionals dealing with the broad area of positioning and applications. For this purpose, it will facilitate the discussion of research that leverages current and emerging positioning techniques and technologies aiming at delivering both practical and theoretical solutions for engineering and mapping applications, GNSS-based technologies, sensor fusion, and atmospheric remote sensing, modelling, and applications, based on geodetic techniques. Recognizing the central role of Global Navigation Satellite Systems (GNSS) in providing high-accuracy positioning information today and in the future, the 2nd IAG Commission 4 Symposium will focus on ongoing research for improving models and methods that enhance and ensure the performance of GNSS-based positioning solutions for a wide range of geodetic applications. The 2nd IAG Commission 4 Symposium will be devoted to the discussion of theory, strategies, and tools for modelling and/or mitigating the effects of interference, signal loss, and atmospheric effects as they apply to precise GNSS and other space geodetic techniques. They will address the technical and institutional issues necessary for developing backups for GNSS, integrated positioning solutions, automated processing capabilities, and quality control measures. Besides positioning, another focus of the 2nd IAG Commission 4 Symposium will be on remote sensing and modelling of the lower and upper atmosphere.

This symposium will be carried out in close cooperation with the International GNSS Service (IGS), the IAG Global Geodetic Observing System (GGOS) Focus Area “Geodetic Space Weather Research”, as well as via linkages with relevant entities within scientific and professional sister organizations. The Symposium will be co-sponsored by the International Association of Geomagnetism and Aeronomy (IAGA) Inter-Division Commission on Space Weather and Working Group IIC “Meteorological Effects on the Ionosphere”. Further partners are the Institute of Navigation (ION), the SGI Workshop Organizers of Technische Universität Berlin, and the GFZ Potsdam.

We intend to publish symposium proceedings in IAG Symposia by Springer.

Main topics

The symposium welcomes contributions in all aspects of positioning and applications in geodesy and geomatics, including but not limited to

  • terrestrial and satellite-based positioning system development, including sensor and information fusion;
  • navigation and guidance of platforms;
  • interferometric laser and radar applications (e.g., synthetic aperture radar);
  • applications of geodetic positioning using three-dimensional geodetic networks (passive and active networks), including monitoring of deformations;
  • applications of geodesy to engineering; and
  • atmospheric investigations using space geodetic techniques and space weather research.
