Plenary Panel 2 High accuracy, authentication, precise timing: key GNSS enablers of future integrated applications
Marco Lisi, Indipendent Consultant (former ESA and European GNSS Agency)
In the next months Global Navigation Satellite Systems (GNSS), in particular the European GNSS, Galileo, will provide new features in the field of high accuracy, authentication and precise timing.
These new features might become the enablers of future integrated applications, triggered by the parallel developments in satellite communications and in wireless terrestrial networks (5G).
Higher accuracy (centimeter level) is being achieved not only through the adoption of multi-constellation, multi-frequency receivers, but also with the introduction of a free-of-charge Galileo High Accuracy Service (HAS), based on a PPP (Precise Point Positioning) approach.
High accuracy is deemed essential for the full development of applications based on autonomy, both for civilian drones (Unmanned or Remotely Piloted Aircraft Systems) and for autonomous cars.
The Galileo Open Service (OS) will soon provide a Navigation Message Authentication feature, known as the Open Service Navigation Message Authentication (OS-NMA). Via this feature, users can verify that a navigation message comes from a Galileo satellite and not a potentially malicious source. This new free service will enable an entire new world of applications requiring authentication of user position and time.
Precise timing, being by provided by GNSSs, is becoming essential in many critical infrastructures of our society, starting with the telecommunications networks. 5G, in particular, will raise by one or two orders of magnitude the requirements in terms of synchronization and timing.
With the contribution of leading experts the panel will discuss the exciting, but challenging, opportunities made possible by the integration of GNSS, sensing and telecommunications technologies.
