UK Launches S-100 Maritime Data Campaign
The UK Hydrographic Office and European Space Agency invite companies to build commercial maritime services that combine S-100 data with satellite technology.
Updated on Nov. 5, 2026 in Geography
The UK Hydrographic Office and the European Space Agency have launched an S-100 Universal Hydrographic Data Model Thematic Campaign. Technology companies are invited to develop commercial services combining S-100 hydrographic data with satellite technology, and the UKHO will make relevant data licences available free of charge to eligible projects.
Why it matters
The initiative comes as S-100 moves from development into operational use, providing a common framework for combining multiple types of maritime information rather than treating electronic chart data as a standalone layer. S-100-compatible ECDIS has been permitted for new installations since January 1 of this year.
ESA's BASS programme has backed more than 750 projects and 1,000 studies since 2010, and all newly installed ECDIS must comply with S-100 performance standards from January 1, 2029. Which proposals will receive support and which services will reach market has not yet been determined.
The players
UK Hydrographic Office
The UK Hydrographic Office is the national agency responsible for producing nautical charts and maritime data for British waters and international shipping.
European Space Agency
The European Space Agency is the intergovernmental organisation coordinating Europe's space research, satellite programmes and Earth observation activities.
The details
Companies will explore services combining S-100 datasets with satellite Earth observation, communications, and positioning, navigation and timing data, with potential uses including vessel and port optimisation, environmental monitoring, maritime security, and automated navigation. Germany recently tested S-100-based electronic charts that combine changing water levels with hydrographic data to flag grounding risks.
Timeline
January 1: S-100-compatible ECDIS permitted for new installations
July: UKHO outlined progress on S-100 sea trials and distribution infrastructure
November 18: UKHO and ESA webinar on the S-100 opportunity
January 1, 2029: New ECDIS must comply with S-100 performance standards
Big Picture
The campaign builds on the IHO S-100 Universal Hydrographic Data Model, the framework now being phased into electronic chart display requirements. It positions S-100 as a platform for satellite-linked commercial services rather than only a chart standard.
Companies working in shipping, port operations and marine data services can apply to the campaign for free access to relevant S-100 licences. Mariners and operators installing new navigation equipment will need S-100-compliant systems from January 1, 2029.
The takeaway
Maritime navigation is shifting from static paper-derived charts toward connected datasets that combine water levels, currents and satellite information. Operators planning new equipment should track the 2029 S-100 compliance date.
What happens next
The UKHO and ESA webinar on the S-100 opportunity is scheduled for November 18, and new ECDIS installations must comply with S-100 performance standards from January 1, 2029.
