MARGAL - Seamless Harmonised Service Introduction of Galileo Services using EGNOS for Ports and Inland Waterways applications The identified user requirements were used as inputs for the demonstration use cases. It should be noted that these requirements are user requirements not system requirements, and therefore may not be met to full extend. A number of internal trials and one public demonstration for each of the two prototype demonstration scenarios have been performed. Port applications (27 September 2005) and Inland Waterways applications (6 September 2005) See the dedicated sections for detailed description and results of the prototype demonstrations.
