S-100: A New Era for Electronic Navigation
The new S-100 standards represent a step change for marine navigation. Published by the International Hydrographic Organization (IHO), they promise improvements to safety and operational efficiency, and a reduction in mariner workload.
In our whitepaper, learn what’s changing and how Sperry Marine is well positioned to navigate you through this transition.
“S-100 is more than a technical upgrade — it is the foundation for the future of safe and efficient navigation.”
What is S-100?
The current ECDIS standards — S-52, S-57 and S-63 — have served the industry for more than 20 years. But as technology evolves, these standards are reaching their limits.
The IHO’s new S-100 Universal Hydrographic Data Model introduces a flexible, future-ready framework that enables:
• Multiple interoperable data layers (ENCs, bathymetry, currents, warnings)
• Improved situational awareness without clutter
• Easier updates and maintenance
• Secure, encrypted data exchange
What about Mariner Training?
The S-100 ECDIS introduces new concepts together with new ECDIS behaviour; Water Level Adjustment and the Enhanced Safety Contour are two key examples. Use of the additional data layers needs to be considered carefully, and cyber security implications need to be assessed. It is clear that training programmes must be adjusted accordingly.
IMO is responding to the adoption of the new ECDIS performance standards by revising the IMO model course on ‘Operational use of ECDIS’ (1.27). Sperry Marine will ensure new familiarisation material is made available for the VisionMaster S-100 ECDIS. Vessel operators need to consider how to update safety management systems to fully address the new ECDIS.
