E Navigation. GNSS, Resilient PNT and the perception of seafarers
MetadataShow full item record
The focus of this research is to explore the concept of e-navigation and the testbeds projects associated with it from the perspective of safety of navigation with a more specific focus on the GNSS systems currently used onboard ships and how sea personnel perceives and anticipate the developments in these areas. The research problem is measuring the attitude of seafarers towards specific navigational safety systems by calculating the perceived ease of use of the current in use GPS system, and measuring the perceived usefulness of upgrading the GPS system to a resilient PNT system.The research uses parametric methods to analyze responses from a sample of seafarers to reach results of attitude measurement which can be generalized on the population of seafarers. The research concludes that seafarers perceive a high usefulness of the modernization of navigational safety systems, and that ease of use of the current GNSS systems onboard ships is evident.
