Customer: GSA (GNSS Supervisory Authority – 6th Framework Program) – Telespazio S.p.A.
Duration: July 2007 – October 2007
The Project
The aim of Project HARRISON is to study, design and implement a prototype of a system able to distribute time and synchronization information, in an authenticated and certified from, by means of the signals employed in the currently deployed satellitary radio-navigation system Galileo. RadioLabs involvement in this project consists of a substantial contribution in defining the requirements of the services using the time information, and in definining how a server HARRISON can supply these services to various users.
Radiolabs activities
Provider for the Telespazio S.p.A. company, belonging to the group Finmeccanica/ Thales and Partner of the HARRISON Consortium.
RadioLabs is responsible of the following activities:
- Service requirements definition
- review of existing schemes and methodologies currently used for the transfer/distribution of time synchronization information, by means of GNSS systems;
- Analysis of potential “security issues”, and of the possible countermeasures to the identified threats;
- Description of the protocols employed to distribute the time synchronization information through the Internet;
- service requirements for the proposed system HARRISON;
- Suggestion of possible schems for the optimization of the provided services, possibly regarding different classes of users;
- definition of access protocols for the authentication of allowed users (service subscribers) and standardization process, by using intrinsic characteristics of the Galileo signal (oriented to assurance services)
- Aspects of realization for the provision of time information, taking into account a “client-server”scheme.
