ABSTRACT
The SMILE (Satellite Multi-constellation Identification techniques for Liable Enhanced applications) project is supported by the Italian space agency, ASI (Agenzia Spaziale Italiana); it started in November 2015 and will last in October 2017. The SMILE partnership, including ITSLAB S.r.l.(Prime Contractor), University of Naples Parthenope and Blue Thread S.r.l., covers the different aspects of the project, starting from the analysis of commercial potential in terms of market and business development. Based on current maritime market, identifying the additional necessities of the final users, SMILE project aims to enhance and extend the performance of Vessel Management System (VMS) providing an advanced application solution for the maritime context. The main goal of SMILE is to assure a reliable, not repudiable, robust and accurate navigation system through GNSS (Global Navigation Satellite Systems) and AIS (Automatic Identification System) equipment that are the basis of Vessel Management System platforms. In particular, in the present paper two main technical aspects of SMILE system will be described: the Receiver Autonomous Integrity Monitoring (RAIM) algorithm used to guarantee a robust navigation system, and an innovative vessel authentication technique based on a dynamic masking of information received by onboard GNSS receivers.
