Abstract:	The shipping industry is moving towards an e-Navigation concept where a range of electronic and radio navigation technologies will provide harmonized, safe and reliable support for maritime navigation. Augmented GNSS is one of the supporting technologies for e-Navigation. Satellite Based Augmentation Systems (SBAS) could be used to improve accuracy and provide integrity to users. Vessels bound by the International Maritime Organization’s (IMO) Safety of Life as Sea convention (SOLAS) are required to use type approved receivers. Currently, there are neither standards nor regulations to define how the shipborne receiver has to process the SBAS signal from a safety perspective. Non-SOLAS vessels are free to use non-certified receivers and many receivers apply SBAS information, albeit with no guarantees. Shipborne receivers on board SOLAS ships will be able to use SBAS messages through the use of the Multi-system shipborne radionavigation receiver (MSR) standard [1]. SEASOLAS (EGNOS Dual-Frequency Dual Constellation Maritime Safety Service) project analysed a potential safety service with an integrity concept tailored for maritime and inland waterways users. EGNOS V3 Dual Frequency Multi-Constellation service will be available as of 2025. SEASOLAS project was fully financed by the European Commission under the Horizon 2020 program for research and innovation and has been developed by a consortium led by GMV with the European Satellite Service Provider (ESSP), General Lighthouse Authorities (GLA) of the United Kingdom and Ireland, VVA Brussels and Kongsberg Seatex as partners. SEASOLAS project developed a number of advanced solutions based on a receiver that processes EGNOS V3 data and implements autonomous integrity techniques to deal with local error sources whose behaviour is difficult to model and predict. The proposed solutions aim at, on one hand, providing integrity at user level (by bounding the position error with a high confidence level, i.e. the integrity risk); and on the other hand, fulfilling the required performance, at user level, of the SEASOLAS worst-case scenarios. This paper summarises the main outcomes of the activities developed in the frame of the project.
