NACSET – CS Enhancements

The Galileo infrastructure is in continuous evolution to develop and deploy all the necessary elements and functionalities for the provision of the planned Galileo services. The Navigation Authentication through Commercial Service-Enhanced  Terminals (NACSET) project has been lauched aiming at evaluating and testing different techniques to improve the resilience and security of the system.

The NACSET project is introduced in the CS development strategy pursuing a fourfold purpose:

  • Develop and test an end-to-end key management simulator to understand and evaluate the challenges and complexity inherent to secure key management and distribution (KMS), including NavSec and OS Authentication keys. An important benefit directly derived from this activity will be the definition of the communication security schemata for data exchange between future Commercial Service Providers and final users.
  • Development of a resilient navigation platform (CS-RPP) with improved anti-attack techniques based on different assisted solutions i.e. assisted navigation message and signal authentication, time synchronization, external sensors. The CS-RPP will include an user terminal (UT) consisting on a GNSS terminal client able to perform attack detection and protection, and calculate resilient PVT solutions making use of different data and signals sources.
  • Support the provision of a prototype Synchronisation and Authentication Service (SAS) to external users based on the aforementioned platform.
  • Carry out research on aspects related to the Galileo CS which have not been covered by previous activities, aiming to obtain valuable conclusions for the definition of future evolutions of the service.
