OSI Maritime Systems (OSI), a global leader in integrated navigation and tactical solutions for naval and maritime forces, today announced the successful completion of compliance testing against NATO STANAG 4564 Edition 3 by DNV, making OSI the first company to achieve this 3rd-party, independent assessment that will lead to certification.
DNV is one of the world’s leading independent assurance and certification organizations.
The successful completion of testing marks a significant milestone for OSI and reinforces the company’s commitment to delivering surface and subsurface WECDIS capabilities that meet the latest NATO standards for interoperability, safety, and operational effectiveness. Edition 3 of NATO STANAG 4564 represents a major advancement in Warship Electronic Chart Display and Information Systems (WECDIS), incorporating enhanced requirements designed to support the increasingly complex operational demands faced by modern naval forces.
NATO STANAG 4564 Edition 3 represents a significant advancement over Edition 2, introducing enhanced requirements for interoperability, standardized operational functionality, and support for increasingly complex naval missions. The updated standard expands capabilities for both surface and subsurface operations, including improved support for high-speed navigation, precision pilotage, operations in GNSS-denied environments, and other mission-critical tactical functions. Developed through the collective experience of NATO navies, Edition 3 establishes a more comprehensive framework for modern warship navigation systems, helping ensure greater operational effectiveness, safety, and coalition readiness.
OSI worked closely with DNV throughout the testing program to ensure a thorough and independent assessment process. The successful outcome reflects OSI’s ongoing investment in innovation, quality assurance, and customer-driven capability development.
The achievement further strengthens OSI’s ability to support naval and defence organizations seeking advanced WECDIS and navigation solutions that enable interoperability across allied fleets while enhancing mission effectiveness in challenging operational environments.
As the demands on modern naval forces continue to increase, OSI remains focused on advancing navigation technologies that improve situational awareness, operational readiness, and maritime safety for navies worldwide.
Quotes:
“The successful completion of NATO STANAG 4564 Edition 3 compliance testing is a significant achievement for OSI and a testament to the expertise, dedication, and commitment of our team. As naval operations continue to evolve, our customers require solutions that not only meet today’s operational requirements but are also aligned with the future direction of NATO standards. This achievement reinforces OSI’s position as a trusted partner to navies around the world.”
Jim Girard, President & CEO
“First, I want to thank the team for their amazing dedication to this feat. Edition 3 raises the bar for WECDIS by incorporating a broader set of operational, interoperability, and mission-support requirements than any previous version of the standard. Achieving compliance required extensive engineering effort across system functionality, human-machine interface design, navigation workflows, and operational assurance. The result is a next-generation capability that enables warfighters to operate more effectively in contested, complex, and multinational environments while maintaining the highest levels of navigational safety and mission readiness.”
Jordan Pratt, VP, Software Design
