An engaging webinar exploring humanity’s journey in navigation—from using Polaris, the North Star, as a timeless guide to today’s Global Navigation Satellite Systems (GNSS) and the emerging role of Low Earth Orbit (LEO) navigation satellites.

With more than 120 operational navigation satellites transmitting diverse multi-frequency signals from several global and regional constellations, GNSS has become a fundamental technology for precise positioning, navigation, timing, and Earth observation. This webinar will introduce the principles of modern GNSS positioning and highlight recent advances in real-time precise orbit and clock estimation, atmospheric-delay modelling and prediction, and high-accuracy positioning services.

Participants will also discover how GNSS is transforming scientific research and practical applications, including terrestrial reference-frame maintenance, monitoring plate tectonics and crustal deformation, precise low-Earth-orbit determination, ionospheric activity monitoring, GNSS meteorology, GNSS seismology, and innovative GNSS remote sensing using reflected signals (GNSS-R).

Whether you are a student, researcher, surveyor, GIS professional, or remote-sensing enthusiast, this webinar will provide a clear and inspiring view of how satellite navigation is shaping a more accurately mapped, monitored, and connected world.
