Safe Port Operations using EGNOS safety of life Ser vices
Enhancing security
• Encrypt and authenticate position reports (Anyone can broadcast AIS reports claiming to be any ship)
• Protect against GPS jamming and spoofing
• Guarantee on accuracy of position information using EGNOS protection level (Galileo).
Enhancing cooperation
• Electronic communication between pilot and VTS
• Ships agree to follow channel in space & time
• Channels are validated to ensure they are safe and do not conflict

E-Navigation benefits of SafePort….
•Digital information exchange
•Traffic Organization (TOS)
•Navigational Assistance (NAS)
•Maneuvering Support
•Vessel monitoring
Galeleo/EGNOS including it’s SOL service is a vital component Making GNSS based systems more reliable, (WAAS-EGNOS) the uptake of the technology can increase.
