The 10th International Colloquium on Scientific and Fundamental Aspects of GNSS will bring together members of the European scientific community and international partners involved in the use of Galileo and other GNSS in their research.
The colloquium will address several major areas of research:
- Scientific applications in meteorology, geodesy, geodynamics, geophysics, space physics, oceanography, land surface and ecosystem studies;
- Scientific developments in physics with a potential impact on future GNSS, particularly in testing fundamental laws of physics;
- Aspects of metrology such as reference frames, on board and ground clocks, precise orbit determination and time and frequency transfer; and
- Scientific aspects of satellite navigation, positioning and its applications, such as signal propagation, precise positioning;
The conference will be organised as a series of plenary talks, parallel half day sessions and poster presentations.

The Association of Public Authority Surveyors, NSW, will hold its 2027 annual conference at the Crowne Plaza, Terrigal, on the NSW Central Coast.
APAS is a non-profit organisation that brings together surveyors and closely allied spatial information professionals employed by public authorities in both New South Wales and the Australian Capital Territory.
The theme for 2027 will be ‘Hook, Line and Plumb-Bob’.
For those who have had abstracts accepted, the next deadlines are: Draft paper deadline: Friday, 13 November 2026; final paper deadline: Friday, 15 January 2027.
