报告简介：
This presentation focuses on the developments we have seen in recent decades in the field of satellite positioning and navigation (PNT services using GNSS), showing examples of the most significant results achieved to date and highlighting the issues that currently concern users who, in safety-critical areas, need to rely on the continuity and reliability of PNT services. We assess the impact that GNSS disruptions can have on society in general, as well as the current options to avoid them.
We then look at the revolution in PNT services that the new forms of positioning, based on constellations of small Low Earth Orbit (LEO) satellites, may bring about in the near future and the contribution they will make to minimizing current problems. We discuss the impact that these new developments may have on precise positioning services for the mass market and how this could change the way society organizes itself, moves, and interacts, as well as possible contributions to deepening our understanding of the dynamics of the Earth system, towards a more resilient society. Finally, we analyze the aspects to be taken into account in order to make the most of the GNSS and LEO systems available, looking for the implementation of new PNT solutions on Earth as well as to the role they could have on the exploration of outer space.
